Monday Night Meatloaf 124

[Music] but I'm a stools on time so I got meatloaf here for you a bunch of the cool stuff that changes in the shop some viewer mail working on another collaboration project with another youtuber what else and there'll be a little bit of machine work in here we're gonna take a look at putting a corner radius on an end mill when you're up against the wall had that been right and let's see what else oh and there's some just a little bit of machining from the collaboration project it was a simple part but there was one operation on it that was a kind of interesting kind of fun that you guys did kick out so let's dive in let's check it out this first thing here is kind of interesting you know for a while on YouTube the advertising prior to the videos was these things were showing up there on pretty much every darn ad and and I think Adam booth showed one of these on on a video recently so what these are it's it's a it's a it's a deburring tool for the outside of an object not a finger but you know if you were gonna put a little chamfer like that right that's the general idea and if it's in a fits in a cordless drill it's got three three flats on it so that doesn't slip on the Chuck but and somebody sent me this and and forgive me but I forgot who it was but what struck me was this is like a super cheap tool okay I mean these things are five six seven eight bucks something like that or three four ten dollars or you know I don't know what they are but you can look them up and they're they're pretty cheap what I wanted to point out what I thought was really interesting was how they made this damn thing okay and excuse my french there so this is okay guys the guys that are entrepreneurs out there and they want to start their own machining business okay don't focus on commodity items right I'm gonna call this a commodity item because it's mass-produced right so if you'll take a look at this you'll see how I got to believe this was made offshore right somewhere that's the only place you could economically produce something like this right but look at how this is made so this is four axes machining here guys alright and you can see the you can see the tool paths that they use to create this thing so what that means to me is these are machined from solid okay and maybe machined in the and probably not in the hard condition but and it looks to be plated so you think about all those steps right you got to buy some material you got to program this thing and your spindle is doing one of these at a time right so this is not a good use of your entrepreneur machine shop time right so this is your competition and they sell them okay say they sell them for ten bucks right what that means is the distributor bottom for five bucks okay and the manufacturer made them for two dollars and fifty cents kind of on the outside right so everybody's keystoning the you know as they go up the chain now if I bought this for nine dollars and I was gonna resell it at the flea market on my table I bought fifteen or twenty bucks for it right and you know so everybody's jacking it up a hundred percent right so or doubling the keystoning the the cost so it's kind of scary actually that they have that much time right that they can produce this part that way right instead of some other manufacturing method you're right or maybe I'm like totally off-base here and they just did this because it's cool right and those tool pads look cool on there I kind of don't think so so fine maybe they got a whole bunch of these lined up you know on some multi spindle indexer or something like that right they have those you know with six or eight spindles that rotate in unison and then the spindle works on one at a time or whatever one at a time but so Tom's advice to entrepreneurs wanting to have their their own machine shops is find a niche okay have a machine that's bigger or smaller or more precise than everybody else right everybody in the world is fighting for the little the the brac the flat aluminum plate with four holes in it right don't compete there compete somewhere that nobody wants to compete in and get good at it okay so anyway there's your competition right there this next one's this next one's kind of funny actually because it's a it's more of a joke then then than anything else so we got this little book here shop terms and you know this is this is an official book here right so this is the Department of Education looks pretty official right so having a YouTube channel and not being very good at pronunciation so you guys all know that about me probably if you've watched my channel and frankly I I it doesn't matter that much to me it's it's more entertaining for you guys right when I when I botch a word but want to get all the time from our English and Australian folks is the pronunciation of the of this metal here okay so this is al on the Periodic Chart okay and but what I thought was funny is in this book let's go find it here is they have it's what we have is there's a whole bunch of yeah I had to change the exposure on the camera here and they have how to pronounce you know some common technical words right like aluminum and so let's see when you can find it here so there it is so you know we always you know the Brits and the Australians always give us crap for how we pronounce aluminum right so I'd like you guys is to to work along here in your respective places where you're sitting and pronounce that word okay Lu num okay so not that's official okay that's official by the Syracuse Education Department right so you know if if the Brits or the Australians out there can produce a similar reference material on the correct pronunciation of that word I'd be happy to take a look at it so like I said this is more of a joke than than anything and I do believe that the the Brit pronunciation is is technically correct although it's not the the accepted standard pronunciation here okay oh let's look looks like up another one here well as well I'm there because I think yeah here's here's the other one right although it doesn't say it's hard to do this upside yeah so the Brits say solder ring because there's an L there right soldering okay that's American alright probably wrong but it's American the L is silent okay anyway have fun with that I got a laugh out of it hopefully you got a laugh out of it so okay so this is kind of cool this is a this is a collaboration part with Saunders Machine Works and John contacted me and asked if I wanted to be part of the the Johnny Five kind of machining collaboration and I think he's asked a bunch of other YouTube folks to uh but their interest and helping out and I said yeah sure I'll help out and so anyway this is the part that they sent me and I said I don't have a lot of time so I don't make it too don't make it a Paolo like let's just put it that way so this was all done manually just you know for folks out there and so it has a couple of little challenges in it that that you guys might be interested in the so what are those challenges so the first challenge is now this is this is typical of and this you know I mean I don't mean this is any any slight or any negative on the the designer that designed this part necessarily but this is typical of of CAD people right people that use CAD a lot right and maybe don't design parts for machining okay so you see some kind of route radiuses here right and but in particular the route radiuses that that don't have a round corner here right so you know if you're producing this on CNC right you know a lot of this stuff is fairly easy right but this part it has radius is here it has this radius here so this is at least a to set to set apart actually maybe more than that let's think about that so you can do this all from the top so let's say you 3d profile this whole thing so you can you can get all this stuff in one set up right you can't get the whole so you got to either rotate it up like this to get the whole and then whatever you're holding on to at the bottom let's see how what you do that I'm thinking three axis here actually so if you have a five axis you can probably do it a different way you can leave a tab on the edge or something like that anyway I haven't really thought it through for CNC ops but I did it manually so that's all that really matters here but this is kind of an odd radius here which presented a problem so and we're gonna I'm gonna show you how to do this here but what I did was I just put you know I had a you know normal to fluid end mill here and I just put a corner radius on it that was equal to that okay easy enough to do right and the reason I want to show you guys is because we've all kind of run into this if somebody throws a radius on there and it's not something you have a tool for right so you either have to order something or you know if you need to get the job done it's easy enough to put a corner radius on a two flew ten mill or a four flute for that matter doesn't really doesn't really make much difference right and I'll show you guys how to do that because I got another another tool here that we can just throw a radius on that and kind of show you how to do that so what else were they gonna say about this thing um I don't know I think that's it but it's fine don't worry about it we're gonna send this and it's going to get put together the due date was November 30th so we're pretty close to that right now I used up on my my cushion and then we're gonna send that off and and it'll go on the go on the robot and it's a part of the some laser bracket or something like that I know this piece was just to support that while I machined it just so you guys know and then this was a machining fixture I did to do this radius here and we're going to see that right now here's what you're gonna need so you need your tool obviously and then you need a you need a radius gauge so that you can you can excuse me you can check the the corner radius so the first thing I do is I just take a look at it and go all right like I can see how much I need to grind off right the trick is to not go too far you want to kind of work slowly right so there's a roughing stage which will do on the bench Greiner then I use the the diamond lap actually to do the last little bit so I get a nice smooth finish on it and it doesn't leave doesn't leave lines in the part when you when you're machining okay and then you need to test the tool as well to make sure that it cuts properly that you have you know you have relief behind the cutting edge okay so what we're seeing here is you see a primary relief which is that little land and then a secondary relief right in our case we're just gonna because you know it's a not a production tool right so we'll probably end up with more of just a single relief that's probably equal to something like the the secondary relief it's a slightly larger angle we want to be able to see the relief I guess is what I'm trying to say so there's there's primary and then secondary really secondary and then massive clearance relief there so there's kind of three there actually there's only two ok so there's part so that would be the primary and then that's the secondary which is big so you know that doesn't f3 so that little light edge secondary okay primary secondary ok so let's go over to the bench grinder and we'll I think I'll just do one corner okay just you know gonna want to you know want to watch this forever right we'll just do this quick and then you guys can try it on an old an old mmmm in mill and then do a test cut and see if you can handle that we're gonna use the tool rest here right and so you got this would be 0 and then this would be 90 degrees so you always want to be a little bit careful too you're gonna come up a little bit short of 92 right so what I like to do is kind of hold the tool with a slight amount of clearance okay not not a lot like that but just a little bit so that you know you have some clearance right and then what I do at first is I just do a couple little little facets right so I faceted two kind of rough in that radius right and then I'll do a sweep to smooth it out now I suggest a pretty fine wheel right you don't want this to go real fast here right so last thing is you know look at the the kind of radius that you're looking for here right and kind of judge what you're what you're doing there so let's let's go ahead and do this [Music] get my magnifiers on here so I'm gonna hit it at kind of 45 to start with so now this is where I gotta be a little bit careful right and it's never too early to give it a quick check and see where you are okay [Music] let's take a look at the backside there okay so judging from that I got I got a little bit of downhill angle to it so and I'm taking away or I'm grinding along the secondary relief there so I know I got clearance okay so I'm pretty confident that that's a good angle our working angle there [Music] so you see up it's you know it's a it's a point so the grinder takes it away fruity fast so you got to be you got to be careful so see we're already getting pretty close here and in fact if they see I need to come around this side a little bit more you think I'm going to do that then I'm going to shift over on to the diamond wheel because it works a little bit slower [Music] particularly that so there you can see the back side and you see it's kind of bumpy cuz I'm hand-holding it but that's okay [Music] I'm gonna go a little more because the the diamond wheel is pretty slow too that's the other thing so it's always this judgement you know how heartily go here [Music] better than you know honestly I could go for a finer wheel in this case but it's okay right now sneaking up on it [Music] yeah I think I'm gonna shift over to the diamond wheel now okay like I said I'm only gonna do one flute and you want them equal they're as equal as possible so let's go over on the diamond wheel and then we'll finish that up and yeah look okay so this is a where I have this this a Q finish grind area there's not a lot of space around that they get the tripod so I'm just cleaning the wheel a little bit right now and you can see it's slow speed this is a 360 grit wheel here right and you see the smooch coming off there that's and this is a premier synthetic grinding compounds or grinding fluid okay so the trick attention to what I'm doing here so I get the table set at a little angle here just still yeah so I think now ideally you'd be doing this on an optical comparator right to do a real nice job of it you know I think I'm going to switch to a finer wheel here because I'm right there yeah I took it pretty far on the the bench grinder yeah looking pretty good so and even this one is cutting a little aggressively here so let me swap the wheel I'm gonna go to a 600 grit and we'll come right back I am back already the wonders of video editing right know once again I'm just gonna clean it and actually your figure works pretty good for getting the you know if you use a paper cloth or something like that it tends to get get to stuff in not a hat hung up in there the trick is that you pay attention to what you're doing and it's not cutting so fast that you you lose control of it yeah that looks real nice and it's pretty good it's a little more not there this is No [Applause] no Alfred Lyon a B tools substituted by any means but it will get you they will get you cutting if you're in a gym okay some are happy with that now there was a little there's a little and you guys can't see it on camera but there was a little bump wasn't quite symmetrical so now I'm pretty happy with that so let me go back on the bench and then we'll zoom in on that and you can get kind of a close-up of it and get a sense of what the finished product looks like there's steak I'm sure I'm in the darn frame alright so there's there's the radius that we just did okay yeah happy with that because I am that's pretty good okay and then now let's turn it around and you can kind of see that you can see my my Chowdhury relief there okay but it's smooth it's pretty smooth I mean there'll be some small lines in the in the park and but it's completely serviceable so any saw that only took a couple of minutes to do all that right so I did did Stu one flute but you know two is not a heck of a lot it's not twice as long to do too okay so and then what I would do in this case is I would I would mark this end though okay to put it back in the drawer right just so when I look at it in the drawer I go hey it's got an eighth inch Reese on it then I just grab it and go I don't have to get the radius gauges out so do yourself a favor label stuff when you put it away and really only saving yourself okay this one is would we call this I don't know so this is a little bit of history here right when you could get real chemicals for the shop now with you know EPA requirements and you know hazardous materials and things like that there's the choices are different let's just put it that way so one of the things that I've been doing is you know I'm working on in the state sale for a friend of mine that that died a while back and one of the first things that we had to do in the in the shop there was to clear out all the hazardous waste right that was kind of our first step and and if if anybody's health or people out there with shops they understand how many chemicals and fluids and buckets of unknown liquids that they have around right so imagine poof you're not there anymore to explain that oh that's a bucket of gear oil or that's a that's such-and-such coolant in water or whatever it is or that's you know oh yeah that's you know rat poison in a little you know you know in a little yogurt container right you know that I mixed up right so just imagine going in somewhere blind right and having to clear all that out well this is something I found in that estate while we were cleaning up and I decided that I wanted to keep it it's actually it actually works really good so but this is this is pretty ancient here and yeah and that's about three-quarters full so that was another reason to to take it so but what this is is it's let's take a look at the other side here and this can be hard this is pure chloral ethylene alright and basically it's kind of dry cleaning fluid and there's some interesting things on the labels here let's see here darn it where the heck is that another that if he experienced headaches or dizziness increased fresh air and then there was a about deliberate use so it anyway I'll let you guys read the thing but this is pretty well at one point this was you know considered safe to use right and now if I was using this I would probably wear gloves and and have a fan going so that the fumes weren't weren't oh there it is deliberate yeah deliberately concentrating or inhaling the contents oops not good so anyway some ancient gauge block cleaner and and you know it's pretty intense when you when you use it but I'll tell you it is an awesome degreaser and it takes everything off and doesn't leave a film which is a kind of the important thing so anyway I thought you guys get a kick out of that this is the old shirt amico label that you don't see anymore either so so what this is is this is a motor and gearbox for my lap master 15 lapping machine so I don't think I don't think I've shown that machine on video yet but I will soon I bought it and a local company that was closing down and they were selling off some equipment so I got it for a pretty good price and so I've got it all taken apart now so there's not a heck of a lot to look at but I'm just kind of giving you a little primer here that this is coming up we're gonna we're gonna try it out pretty soon because it's almost ready for ready for prime time but what happened to this gearbox was pretty spectacular from a so you turn the thing on and it just sounded like a bucket of bolts running so was clearly there was something wrong with it right so what had happened was the previous owner they didn't clean out the the used abrasive and slurry basically and it kind of hardened and caked up and then it overflowed a weir that protected the gearbox so what happened was this abrasive material ended up pooling up in here and filling up and then just working its way through the seal and going into the gearbox so the I put a little post up on Instagram for those guys that followed me on Instagram they probably saw the pictures of the bearings that were completely blasted so anyway I got it all back together the the surprising part was the worm and the gear were in pretty good still in reasonable shape or usable shape so replace all the bearings all the seals you know cleaned it hot tank the thing just you know did a did a proper rebuild of it so it's all going back together now what you see here is so it has it has opposing tapered roller bearings because there's some thrust loads on it right so there's a set of or a package on this side a package on this side so there's a particular distance between those bearings that that has to be controlled and then the gear still has to be centered on the worm coming in this way right so there was some kind of tricky measuring and whatnot and the way the manufacturer handled it is they used peel shims so they those are basically shims of a particular thickness that are laminated together and then you you peel those shims to contains the the spacing so those were kind of chowder Duende came off so what I did was I took some measurements and I actually machine solid ones on either side here you can see that there's one sticker in one's thinner and and to get the bearing clearance correct while the the the warm gear is is centered on the worm so that makes sense I hope it does so anyway that's a lot of yap and for I fixed the gearbox so then the motor bolts on here and then this bolts underneath and they're lapping plate goes attaches to this drive shaft i rewired it cleaned it all and it's going all back together now so maybe the next video that comes out will have this thing running and you guys can take a look at it we'll probably won't laugh anything on it because I got to do a little build a little pump for a diamond slurry and and then we'll do that but then we'll we'll try lapping some stuff or will correct the lapping plate because it's not flat and then we'll lap some stuff and then check it and see how we do so anyway that's coming up and gearbox rebuilding okay so actually this is just an announcement here so some of you may have heard the name Richard King he teaches scraping and machine alignment and machinery building and he actually has this announcement is he has a class coming up here in Northern California Vacaville to be specific and it's in April 2020 so if there's local Bay Area folks that have wanted to learn the the art of scraping and truly it is an art form and Richard is he's an old bugger and he knows a hell of a lot about scraping and machine alignment he's also got some great stories he's a hoot he's a hoot to work with anyway he's he's having a class in April 2020 in Vacaville and I'll put a little link on the in the description so that you can contact him if you're interested in signing up for this class I'm planning on attending the class just kind of as an observer and helper and hang out with Richard and tell war stories and and do a little do a little bit of scraping so he teaches hand scraping okay and then he also teaches power scraping which is about a thousand times faster than hand scraping although requires some some equipment investment this anybody can come up with enough money to to make a hand scraper and go to town the real my belief is the real value in the class is his knowledge about machine alignment and machinery building so if you decide to go to the class that's really what you're gonna want to pick is brain for the this you can practice on your own once you get the fundamentals and but the really deep knowledge comes in you know which surfaces do you scraped first and why and what alignments are you looking for how do you do those alignments and and how do you you know there's just a million things other than learning the physical mechanics of scraping right that's something that you can practice and kind of perfect on your own but the the real the real gems are that that trade knowledge that you're looking for anyway look in the description there's a link to contact Richard and get signed up for the class he does require a deposit so that he can plan his travel and all that so but you're on your own you work that out with Richard and hope to see you there what I wanted to show you over here was this is my Brandon Sharpe master and I've got flood coolant on this and so for those guys out there still you know trying to do dry grinding any dry grinding works okay for small stuff but when you you know when you get into bigger surfaces or heavier material removal you really should go coolant and keeps the part cool keeps the stuff out of your way and better finishes there's all kinds of advantages so but I just wanted to show you the setup because I created a an ox tools you know rendition of a coolant tank with a pump and a nozzle system here that you guys may be interested in so I may have shown some of this a long time ago when I was working on this but we'll go through it and we'll take a look at it okay okay the first part is the the actual nozzle here now I'm not smart enough to think of this idea myself this came from Robin Renzetti and in fact he even sent me these tubes and their sign means together and they're they're soldered together and then soldered into this brass block but what it does is it allows me to direct the flow right at the interface between the wheel and the and the work right and then this distributes it widthwise so they cover the whole wheel there right yeah I got a beveled off and then this is me here this is a this is actually from a photo you know photography like you know B&H photo I think they had these on sale for 20 bucks or whatever but it's basically a Noga arm right and so now I can I can get up under there put a right where I want it and lock it down and Bob's your uncle okay and then back here I have a valve a ball valve then I can control the flow with so that's full flow and then that's off or teeny bit of flow but you know whatever you want so you can control the flow here locally and then what I did was I put the pump on it on a little wireless remote control and I don't want to turn it on right now because I want to show you the tank and the Weir's in the tank and in the settling volumes that are that are in the tank okay I want to show you that part before I get everything all the whole system wet again okay all right so anyway so when I might cool it being I hit the remote control coolant comes on Bob's your uncle turn it off and you know I have to reach for a valve or excuse me a reach for a switch or do anything like that and it's it's right on you know you got it you know what me that's me what I do is put on a little magnet here or something like that and I can stab it here I just keep it on a shelf down below okay so let's look at the tank and maybe give you guys some ideas for your own this is all very cheap to to make and with readily available materials so first thing to note here is it's on it's on okay and this is just a Harbor Freight furniture dolly and it's actually kind of a crummy furniture dolly but it works great for putting this little coolant tank on and you can see it fits pretty good so cool it returns here and this is a flexible hose that I can just I can just pop out of there so that I can bring this out and mess around with it okay and then this is just a cover for the strainer and filtration okay okay just pop that out and these are just a couple of strainer baskets here so that I can hold the screen in the right shape and it has a collection point so now you can see now you can kind of see inside here what this is this box is this is just a partitioned parts box sure I'm still in the frame there properly yeah it's a partition parts box from mcmaster-carr I think this was 12 bucks or 13 bucks and then the dividers which are not just like this so they fit together so you can create a different size openings in it are a couple bucks apiece alright so and then the lids the the lids a couple of bucks too so but there there it is I got a submersible pump so kind of dirty cool that comes in kind of gets strained in the strainer and then drops into this into this pocket here and then coolant fills up and spills through the notches in the in the in the Weir's okay and they're just below the surface right so so anything heavy drops to the bottom fills up into that but now it fills up into that one so by the time it gets over here it's relatively relatively relatively good shade now this here so I attached the so gluing gluing and sealing plastic can be a challenge this is what he is there this is 3m and re marine adhesive sealant 5200 works great takes a long time to drive but it works great and it bonded this polyethylene here perfectly and and then you can see there's little slots of these fit into so sealing it up wasn't really a problem and the pump is the most expensive part and I want to say that was 80 bucks and I bought it for another project but so I just kind of reused it here so that was the most expensive part of the whole thing what I'm using for my cooling and I'm pretty happy with it it works pretty good and I just plug that back in there and roll back into place and Bob's your uncle right so let's turn it on and you can see that see the remote control and all that stuff you there goes and then off so this is a this thing just came from Amazon it's just a remote control for you know a light or a radio or something like that and I know I think it's good to 10 amps or something like that so it's pretty good and you there comes and then I can I can switch get more flow or I can shut it off here locally if I want or just get a teeny bit if I want just a teeny bit so just depends what you're doing anyway so there you go give you some ideas and for your own shop this next one comes from a friend of mine Phil Koerner otherwise known as the tool and dye guy and Phil's a he's an interesting character he's been in the trades since he was a teenager working in his his dad's shop I believe and he's had in Erie Pennsylvania and he does these you know I call him and he calls them boutique calendars each year they've been they've been successful for him and a lot of people are interested in them they're they like tools and you know everybody needs a calendar right so this is the 20 20 calendar here and this was a little different than previous years they've been the kind of the flip ones with pictures of tools and things like that and I have to say that my preference is this whole year calendar it's kind of useful in my mind you know you're kind of tracking progress up throughout the year right and when you're only looking at one the time sure the squares are bigger but you're just looking at one month at a time you don't get a sense of how fast your time is going I guess is what I'm getting at so anyway Phil does these calendars I think he's got a bunch of them and so if you want to send a nice Christmas gift to somebody there's a link in the description check it out and help a fellow metal worker out and in buy a calendar from them and and make somebody's day when they get it so or spy it for yourself anyway they're reasonably priced and you're helping out a fellow tradesman and that's always you know nice thing to do so there's another bit to this here let me a trade here so I bought both of these okay and this one is a it's a nice cutaway of a Lufkin micrometer right and so yeah you know it's a shop art okay so this one you know this one will last more than a year right and what's interesting is the fills actually use a Lufkin fan and so am i this is a brand that used to rival starett and brown and sharp and now they're you know they're big businesses well that's a Stanley is tape measures okay that's all they do anymore so if you're looking for tools high quality machinist tools check out this name on on eBay they make some beautiful stuff in fact they're satin chrome and their graduations are some of the best in them in the business and in fact I think they are the best myself I have some Lufkin micrometers that are just absolutely gorgeous in comparison to the other guys so once again I you know I don't know what he charges for this but it's totally reasonable and yes this is a you know I'm helping a friend out and so there it is right big deal so if you don't want to help him out don't do it if you do go for it all right so anyway Lufkin micrometer and a calendar good shop stuff so this next one this is basically kind of a shout out to a good vendor okay so and you know I it's it's not any kind of a sales pitch or anything like that I just want to communicate an excellent experience I have with a vendor okay so you guys know I have it's a PR pros digital readout on this VM plate right and I was like I don't know I've had it for actually quite a few years now and it functions wonderfully okay it works fine and but recently I had a problem with the the x-axis and it was it was skipping counts and you know generally misbehaving as the Dro right and so typically you go in and you clean things and you realign things and then you try it again did that and helped a little bit but then it came back again so wasn't quite sure what was going on right so they have a I guess it's a tech help email and I just emailed them and they got back to me right away and you know my question was basically hate my x-axis is skipping so I have magnetic scales blah blah blah skipping give me some idea what to look for here help me out what could be causing that right and their answer was we don't know and but we're gonna send you a new radio right now and they did and so they didn't mess around I was having a problem I told them I did tell me what I had tried to correct a problem but they didn't really have any any additional advice I said we have no idea why that's happening it sounds like you did everything right we're just going to send you a new Reid head which they did and guess what they fix the problem so now they're your local here in California they're up in Fairfield they think and nice bunch of guys been over there to their their shop and looked at some of their machine tools and the Dro choices and probes that they have and things like that just a couple of nice guys so if you're looking for a Dro check them out okay for the money these are excellent dr.oz and and excellent customer service ox cool thumbs up okay so take it for what you will and you know go from there you're adults make your own choices all right see you later this is this is pretty cool here I think you guys will like this this was sent to me by a friend of mine James rich in he's in Colorado and he said hey there somebody's getting rid of some some cool stuff are you interested it's like you know what to bait your hook with right of course I want to see right that was the short answer and so we did a little we did a little horse trading so to speak and James got something he wanted and and I got the the mystery item here so what we have here is something that's actually pretty special let's take a look so for those of you that don't know what this is this is what's called an optical polygon okay and it's a very kind of special reference standard okay so it's an angular reference standard and I'll show you how that works in a sec here so this one so some of them are made out of out of glass some of them are made out of carbide some are made out of steel this particular one is made out of steel and made by a Coventry gage company also sometimes goes by the name matrix or though maybe that's what they call their tools I don't know and I know it's one in the same company coventry gauge and matrix you see matrix gauge block sets in Australia and in the UK very rarely here so in the UK so it says based on alternate here based on NPL design so NPL is a National Physical Laboratory so this is like the Bureau of Standards than in the UK so now this one's cool because it's got 10 degree increments here so it has a it has a little flat face here I'm gonna pick it up here it's not super easy to get out of the box here let me tip it up you guys can see it so each so it looks like it's a polygon as the name would would lead you to believe but what we have here is we have ground lapped and polished faces that have a very very accurate angular index between each face okay and and they're reflective and they're supposed to be reflective because what we use is we use an auto collimator to look at this okay so that surface needs to reflect back like a mirror okay so the way this is used so yeah how the hell do you use it right so there's all kinds of ways you can use this so you can actually attach it directly to something that you want to index okay very accurately so for example say we wanted to we wanted to index this very accurately in ten degree increments I mean very accurately what you might do as attach this to the end okay not not maybe a good example here okay attach this to the end then we would look at those faces with an auto collimator then we would rotate it and then the autocollimator can discriminate fractions of arc seconds of angle change so we would we would zero on one face and then we'd make an index and we zero in the next face and this would be a very very precise ten degree rotation so that's one way you can use it the bigger way that they're used and that let me let me pop this out here and get this get this out of the way I set this on this because it makes it easier to pick it up the other way you might use this your yes is to calibrate a rotary table okay so here we have now this particular rotary table it's also very special but it's it was the only one I had that was big enough to kind of set this on kind of properly right in fact this is probably the same accuracy and possibly better than this so just to kind of put it in put it in perspective but what the way we do this is you put this on like so you put it on center like that and then I need an analog here let's let's pretend this is our this is our autocollimator looking at one of these faces right so we would zero up on one of those faces and then what we would do is we would make we would make an index with this and then we would take another measurement on the next face so we'd make an index equal to the spacing of the of the faces here on the polygon right so in this case it's ten degrees and then we would know any angle differences that we measure okay now what's cool this is one of those kind of natural things that happens is everybody knows that 360 degrees is a full circle right so it's a principle called closure and circle closure in this case right so once we add up the errors plus and minus plus and minus plus and minus whatever we get all the way around we actually close the circle and and there's another technique if you have a rotary table you can you can put two of them together and then put this on top and rotate one one way and then rotate the other back the same amount right so that's kind of dual closure so there's so these are if you want this is not something that's great on a great explanation on just kind of a verbal commentary right if you want to know more about it look up do dual circular closure or calibrating rotary tables with optical polygons if you want to have your head explode and read about circle closure and and how these are used anyway James this is like super cool and so I have an auto collimator I have a spiffy index table and at some point here I'll set this all up and I'll play with it and maybe see if I can get some shots through the autocollimator and we can look at some teeny tiny angle differences so this is probably better I think this is a this is a calibration polygon so it's probably sub arts arc second accuracy I don't know that for sure we and honestly I doubt my abilities to to check it to that level so anyway James I hope you enjoyed the the little little thing I sent you and are enjoying it still and I'm certainly enjoying this and now you guys get to see a proper optical polygon that's this spectacular so I put it away for safekeeping so you know this box is kind of terrible actually because I have to touch the measuring faces as I put it in so I'll have to maybe put a spacer under there so I can get under it a little easier make a handle or something yeah maybe I could do that maybe I could maybe a handle would fit in there I can make a little handle to lift it out you know what I think I'm gonna do that okay one of the things I mentioned in a video a little while back is I was playing around with you guys all know about the three plate flat plane generation right or where you can make a surface plate with no measuring equipment by just matching them to one another okay that's the short story that's called the three plate method if you want to do a little research on it Joseph Whitworth really kind of pioneered that technique and you can create a flat plane of basically any accuracy that depending on your patience by matching three surfaces together and then scraping and and matching those surfaces to one another now that same technique actually works for if you want it to create straight edges right so let's for a second let's have a mental leap and pretend these are straight right now and I don't know if you can see it but I have the edges marked with the engraving there so the same technique these are actually miniature flat planes right you can you can make these surfaces together and then look at the contact pattern and you can actually generate straight edges okay using that same three plate or three edge technique okay and so this is something I've just been you know I just love this kind of stuff right the self-proving and self-generating thing and a little bit of handwork and no measuring tools you can do some incredible stuff right it's that this this fascinates me right and so I've been experimenting with this kind of on the down low you know in the background so what I wanted to show you though is now this one's axe this this one's actually pretty close right now and there's a kind of the spotting pattern on that and so it's it's actually pretty good I don't think I ran an indicator along this yet so another way you can do it is if you have a good surface plate you can kind of true this up and then run an indicator along it and then note the highs and lows and sometimes that's quicker than then spotting them together so to get close and then you and then you match them all up so but what I want to show you is kind of how it was doing right so let's let's do a little bit on this one here now I had this one inked up because I did measure this one on the surface plate okay and I just I just clamped it in a precision vise here and then ran an indicator at at each end to kind of get at a level and then Randy indicator along it and then noted the kind of highs and lows right let's put that on there like that okay okay now technically if you're really good really good at filing right you can you can just do this like this right but it's also really easy to to get tipped a teeny bit that causes you some grief right and so me include it so I made a little a little kind of a filing guide right that that keeps me perpendicular to the to the sides of this right now people out there going oh why the hell does it look like that so originally I said oh you know what I'll just put some cam flowers in there and the idea was that you could just kind of change position or even actually file like this if it was kind of a big spot right and you know this is tangent with this this edge that it's referencing here right and then I couldn't find another camp fall in my drawer so I had a little plate on it and anyway I was using it that way and then I said you know what I want to improve this a little bit so I made another block and have it it on there now I have a kind of a proper shelf there okay so I'm sure you can do better than this this is this me goofing around right it does work so so in this case the blue is I don't want to touch the blue I want to touch the black and I mean let's see ya know this use that one so this is a pillar file okay these are really really nice files and I can thank my friend Robin Renzetti for kind of turning me onto these and you know I've been a bastard guy for and that's a joke right a bastard type file for our mill violations a bastard cut right for many many many years and he says though you have to try a pillar files right and I just kind of brushed it off a little bit then I I looked through my inventory and I actually had one and I tried it and I kind of liked it now they use a different numerical they use numbers to indicate the coarseness of it so see if I have a real course in here so here's a there's a zero double lot and zero or you know kind of like a gravel road and number four or number six is like glassy smooth okay this is a four here anyway and they have safe edges that's the other way you can tell them they have to safe edges which is great when you're deburring parts and stuff like that you know - booger up the sides as much okay so here anyway enough of that so here's how I use this thing I just kind of hold it down and I just draw file and now it loads up a little bit right so now what I can do is easily move it over a little bit and then I'm cutting again like so okay but what the main the main thing here that I'm doing is making it very perpendicular loads up a little bit and this is a real fine file by the way it keeps me real perpendicular so there I'm not rocking the thing and creating kind of a round you know shark fin there in the middle or whatever so whatever you want to call it okay so anyway I just want to show that you know this is this a simple filing fixture that you know one of you would Chuck's out there with a with a good table socket make one of these pretty easily right and so here's so here's the kicker right you can make these as long as you want right so if you needed a six foot or an eight foot straight edge you can do it right and you don't need a milling machine you don't need a surface grinder okay what you need need a file in a block okay and some and some sharpie or spotting ink and you're off to the races so that's the beauty of this right if I'm on a desert island and all I got is his palm trees and coconuts right and the wreckage of a ship with some steel in it I can make some really really excellent standards in the middle of nowhere okay so that's kind of stuff I like and that's why I like this process and why I'm showing it to you so do with do with it what you will so this next one is kind of a question that I want to put out there if somebody started thinking about it so here in the United States you know you have machine is she a woodworker she an electrician and with many of those trades there is kind of an associated group of tools and tool boxes so what I don't know what I don't know and I would like to know more if somebody has some good answers is what are the typical toolboxes in Europe or England that kind of machinist or tool makers or die makers or you know they have these same types of skills and needs over in Europe right or anywhere in the world actually and I'm guessing that's probably similar so when you become a journeyman maybe you get a something the equivalent of a Gerstner box and that's kind of a sign or signal that you've arrived and that you've served your your your learning time and whatnot and and all that so here in the US we have you had typical Kennedy machinist and you got Gerstner machinist and by the Wasson I can't think of any others off the top of my head so the question is what do machinists and tool makers in European countries used for toolboxes is there a brand or a name or a kind of a tradition associated with that so that's my question throw some in the comments or shoot me an email and maybe we'll bring it up again on another beat loaf and mechanicals a circle on the on that whole thought okay thanks for watching guys and I appreciate your your viewership thank you [Music] you [Music]
