Adam Savage's One Day Builds: Knurling Tool Storage!

[Music] foreign Savage here in my cave with a well this is both the show and tell and uh uh one day build for shop infrastructure I have to admit every now and then I build stuff while you're not looking that's totally something that happens and it's often based on the fact that I kind of need to build something and just be concentrating on the building entirely and to not be thinking about the storytelling it's a mode I love to do clearly because of all the content I put on here and there are times when I don't want to have to think about that and when we wrapped silicon the pop culture con I threw I throw in in San Jose every year the lead up to it took a tremendous amount of energy and at the end of any project like that I always have a little bit of a a dip creatively emotionally there's just a reset uh I I have learned this about myself over the years and so I prep myself for it and I think you know go easy on yourself don't try and line up too much right as soon as you're done you know you want to give yourself a little time to reset and wrap around the gear switching so when I finished silicon this year I realized I wanted to make this tool and this is a clamp knurler and it is a I came in here without plans and without yeah mostly without any plans and I built this it's not my design the original structure of this clamp knurler was in uh used by a company called marlco m-a-r-l-c-o and they made a clamp knurler that you can still find on eBay they're terrific knurling is the process let me start there knurling is the process of putting a pattern like this diamond pattern here on this knob knurling doesn't have to be a diamond pattern it can be a straight pattern you've seen little uh adjusting knobs on cameras often have little ridges that is also those little ridges are are created through the same process knurling so that the knurling wheel for straight ridges is straight and the knurling wheel for a diamond pattern are two opposing hardened steel wheels and these two things are the only things I did not make here because you can buy these you can buy these for like seven bucks a pair you can buy small medium large uh diamond cut and small medium large flat cut I have all of those and so I made my knurler so I could swap out the wheels that was one of the features but the inexpensive way to knurl is to take a tool that is usually a clevis of Steel that is a a bar of Steel with a notch cut out of it and a pin that goes through the wheel and you just you put that in your tool post you clamp a piece of work in your lathe and you just push the wheel ah really hard into the peace and this is this puts a huge amount of pressure in the wrong way to the bearings of your lathe I have a big lathe so it can take that but it's not like it's not like you want to do that so A clamp knurler is beautiful because per its name it clamps on both sides of the work all this will be apparent later I'm going to use this and show you how it works but it clamps on both sides of the work and thus takes all the stress out of the machine and I have long wanted a clamp knurler I used a cheapo one uh like 20 clamp knurler to make the neural on my lightsaber recently you can see the shot here of that knurler in action and that one worked great for what it was and I decided to make one a lot prettier so moral code like I said came up with this design and then Hemingway kits and I have built their kits before [Music] um they are kits and the real truest sense of the word because they don't do any of your work for you you get like a cast iron piece that is not squared and not drilled out or anything it's just the raw cast iron and then you get steel chunks for the rest of it and you get a set of plants two or three drawings in order to to make your parts and the tolerances are all listed and uh there are pictures of it Hemingway kits um is a wonderful wonderful company uh like I said I have built this uh this tool Maker's Vice I built using one of their kits and I use this all the freaking time this is a fantastic device it is uh very useful to me and it was one of the first Hemingway kits I made they make a clamp knurling kit why didn't I build their clamp knurling kit it is simply because when I finished silicone I was so I didn't know you know I never know what the reset is going to be like not to say I don't know how long it's going to last it's usually about a week or two but like I didn't know how I was gonna work through the week after silicon is that Monday occurred and I thought I want to make a clamp knurler and I just I don't want to wait whatever it'll take a week or two for to order one and get it here I want to start building it tomorrow morning and so I just sat there looked at pictures of Hemingway's clamp darler and Marco's clamp knurler until I understood their structure which is a there's some interesting complexities to the structure which I'll reveal as I as I put this together it is an ingeniously compact design that applies a huge amount of uh reinforced Force to the work such that you're laid like I said receives none of that abuse I will build another one of these on camera that will be a one day build the reason we're looking at it today is because this tool is going in the the the the knurling drawer of my lathe tools cabinet and I want to make a holder for it and for the various sizes of uh hardened steel knurling cutting wheels that I have right I wanted to pause for a second and talk about making a tool there are a few things more addictive to me I made a tool over covet actually I'll grab it I made this base for my uh chop saw I made the vice I made the ability to move that Vice I made a stop for that Vice uh and I did this all with the same kinds of materials brass cast iron basically scraps I had here at the shop and when I built this I I really stared at it for days seriously uh and there's something really particularly special about making a tool that I find more satisfying than most other objects because there are Aesthetics but there's also the Aesthetics of how well it does how well a tool does its job is part of a Tool's aesthetic yeah I mean it may even be orthogonal to our idea of visual or tactile Aesthetics but it's there and I specifically made this thing with very little adornment because I I didn't want to show off I wanted to show right just just the facts ma'am just what you need to get this across the line what is what does it take uh and I've already used this several times and and it works just I will utilize this in this video but here here you go that is a sample I did just to show someone yesterday the nice fat diamonds this makes all right where was I I was saying this thing is insanely simple as a design and really robust in how it applies the force it needs to apply and really simple in its execution it took me a while to wrap my head around all the parts of its mechanical Arrangement and part of the reason I'm shooting this is because I want it to be easier for the next person thinking about building their own clamp knurler uh and by all means you should go get the Hemingway kit because it has everything that you need I had a bunch of extra scrap iron I didn't need their pieces and parts it turned out there was a link to Hemingway's kit in the description uh and if you want to try this you totally should but I will assemble this now on camera and walk you through uh its various components and how it works the clamping force of this is all maintained by a uh by three pieces of brass actually I guess two pieces of brass um this spindle here which has rounded uh posts and it is a single piece of three quarter inch brass machined with a flat on it and with two quarter inch posts uh and this is the top of the clamping Force and I'm just gonna screw this knob down I actually cut the threads on this 3 8 24 Rod myself I don't recommend doing that I have since obtained a bunch of stainless 3 8 24. I like the 3 8 24 specifically because it is the kind of fattest plus highest thread count metal rod at this scale uh why do I want the highest thread count I want the highest thread count because uh if I just had a 3 8 16 or 3 8 18 that's 18 or 16 threads per inch every time I turn this I'm moving this a certain amount 1 18 of an inch or 1 16 of an inch when it's 24 I'm moving at 1 24th of an inch so I basically have finer control over uh how this works sorry over the clamping Force when I have more threads per inch my clamp knurler is also missing a key feature that the Hemingway kit has which is a uh a clamping arm it is still possible for me to add that feature into my knurler and I think I'm going to do it on the next one instead of try and retrofit it into this one it was just one extra step of uh sort of mental capacity that I eliminated to make this build a little more straightforward um so there is the the the top of the clamping force and the bottom of the clamping force is another brass plug also three quarters of an inch also with quarter inch posts on it except that this one has a set screw which captures it here uh and that means that as I open them up uh this uh this doesn't come out that is how the clamping works when I uh when I open when I open this when I close this down it brings these together when I open it up it moves them farther apart and therein is all the action inside of the clamp knurler stems from those two pieces to put the captured nut on there you want it captured so here's a little set screw uh I actually custom turn this set screw so that the end actually fit nicely in there without chafing it I didn't want to mark it up and also I don't want to put it in so far it actually uh touches that Center piece foreign the real trick here is that that capture screw can't be proud of the outer barrel of that plug because it sits inside this piece and the reason for that will be really clear very shortly so this is one of the Jaws that does all the clamping uh sorry that applies this is the jaw that takes the force from these plugs moving apart and applies it out to the wheel so actually why don't we put in the wheels first because like I said I have many different kinds of Wheels uh let's see I won't do this like that uh and I have these little plugs these I also did not make I scavenged these from a clamp knurler because I like that they had these little low profile fat head flat heads and the flat head means that I can get this is how close I can get to the work less than a that's actually just about a hundred thou um and it allows me to get right up to the edge of a lip if I need to same thing on this one and these uh little clevis pins are held in by circlips um circlips are a technology for securing something when you don't have a lot of room they allow for a very low profile securitization of pins I'm going to hold one of these up for you so to see it up close and personal in a second so here you can see the countersunk flat head in there sitting inside of that it's only a hundred thou from there to the wheel and then here is the circlip you see it's just that little bit of hard and spring metal that goes into that little slot and captures this all the forces going this way so I'm not worried about that shearing off that can handle a huge amount of force I'm also not worried about how small this arm is given how Cheapo the clamp Miller I used on the lightsaber was I feel like this is plenty of meat uh this entire thing is held together with uh two screws and three dowel pins a dowel pin is a piece of semi-hardened Steel with chamfered edges these come in standard lengths uh they come in all sorts of standard diameters metric and Imperial uh and it's great to have a complement of them in your in your shop so one of them goes in here yep that's that side and it's mostly just centered between the two and the other two go here and here and that one yep like that oh right and there is one more [Music] then we have now these two pieces end up being the other part of the equation that applies the clamping Force the plugs uh the the plug here goes to the top hole the post here on the bottom goes through the bottom hole and the post here in the middle slides in this slot right here so here's just going this is going to be a little greasy because I really like to use a lot of oil when I'm do oh whoops that too quickly great all right now we have most of the structure and that sits on this under plate now the the best part about this structure is that it is and what I like to think of as an H arrangement in which the two tall stalks of the H are these two flat sides they sit here on either side of this equation and this piece sits between them so this goes in here and sits uh here and that is the entire structure of this device again very very nice and low profile I really dig it uh these capture this slot captures the body of the clamper this slot the opening up of this slot allows for the smooth movement of these but they have no mechanical thing holding them to this except for these flaps it's really brilliant so uh we will put this like this we will put this like this we put a pin in there and a pin in there yep there we go now uh there's one other aspect which is you notice these holes here on either side of this and there's corresponding holes in the insides of the arm that's where the Springs go and so uh the Springs actually are not a mission critical feature of this build but they are very very useful feature um and hard to install actually or just a little bit of a pain to install just a tiny bit that's it great okay so now I've got the springs in here yep I've Got The Springs in here holding this to Center and what you can see is I'm now going to have to drop pull this spout drop this plate on here and then I sync these two uh button heads through and they should give me the structure that I'm looking for so those like that put those in here like that now they come on through holding this down yeah yeah ah look at that we're almost there we're almost home now this guy sits there and once I yeah yeah and [Music] now what's funny is I'll bet you don't need both of these bolts to hold this thing together I'll bet that is enough and so you can see right I uh I turn this clockwise to clamp it down I open it up by turning it counterclockwise it's self-centering that's what the spring ends up giving in is both a ability to sit close to Center but also kind of move back and forth and then we'll clamp this down and the Machine itself is complete oh my God I literally can't tell you how beautiful this thing feels to me um every chamber every chamfer every Edge has been lovingly treated by me with files and steel wool and Scotch Brite I've really worked this over too and it feels great there's no there's no rattling my tolerances are all within a couple thou if not way less I I'm just I this sat on my bedside table for five days after I finished it I actually kept bringing it in to use it and then bringing it home I assembled it backwards so awesome okay uh let's reassemble it [Music] this pin the fact that it moves allows the direction of this to apply a wonderfully consistent amount of force to this top arm and the the force it brings it allows that angle to change slightly which it does as it opens up and still apply the same amount of force [Music] foreign [Music] [Music] [Music] oh okay that is the completed device yeah it has a good side and a bad side because it sits here on the in the in one of my multi-fix uh tool holders so that sits on the right the labels on the left I've actually adjusted all the the dowel pins no same orientation this is actually held onto the rod using Loctite but I also um I actually made this knurl with this tool by using vice grips and they damage the thread slightly but that was fine because once I screwed this down and added log tied and trying to held it all together so that's Never Letting Go um there you go that's the device here are all the knurling wheels that I want to display with it and frankly I want these labeled as to what they are so I can easily pull them out and I need a little bit of a holder for some extra circlips I almost lost one of these just now by dropping it and I have more they're just over there in the Sorting cabinet so again if I'm going to be swapping out these wheels I want the extra little circlips to be there so that that's an easy operation this here knurling tools that is the drawer it's going to go in what are these wheels these are larger knurling Wheels I those are just they're artifacts from other neurlers that I had I don't need to worry about those but so yeah my block is going to fill some of this space and I'm going to make it out of some inch thick is that an inch yeah I'm gonna make it out of some inch thick MDF so let's get started there and then as far as these guys I guess ah right how big is how big is that thing uh hang on six and seven sixteenths [Music] right so let's see here what do we got foreign [Applause] what do you mean five where's that one oh there it is okay so yeah that's one that's two that's three okay so what I have here are seven pairs and I probably want eight so we've got a straight neural light medium and heavy we've got Diamond knurl light medium medium medium and heavy is here that's heavy so if that lives like that [Music] I'm kind of inclined to cut this here yeah and then these guys would sit do I really want that I kind of would rather it be like this yeah that makes sense so one two three four five thanks okay I want that and then each of these could I don't even have to label them because I can see them yeah okay great all right I think that's how I'm gonna do this and then I'll just have a little on that side so this gets cut off this will be used to make that all right my whole spacing is not my whole spacing is not perfect because I added wrong that one's a little fatter but that's fine they're all else pretty great let's just double check that they fit that's great yeah yeah wonderful all right we're gonna try oh I don't need to cut that one very cool all right that's going to glue there like that uh yeah they're just wide enough that's wonderful but we're gonna give this some glue there we go it's the last thing that glue did awesome we're gonna add a little mechanical strength to this just because I like mechanical strength add a couple of screws but I'm going to counter something foreign another one here [Music] [Music] thank you foreign ER sits here the knurling wheels all sit here I am going to Mill out two uh three uh little recesses one will be for circlips one will be for other stuff and these will be for the larger knurling Wheels foreign [Music] [Music] oh there we go that's a respectable looking thing put it in the drawer oh oh wait a minute really no that should fed oh right but it doesn't Okay so it does fit but in getting this in there I need to create a little bit of a relief for the thickness of this and I'm going to use this end Mill that I had holy cow look at that yeah this is going to be beautiful foreign I have one other option if this doesn't work but I think this should work here we go foreign I want to put a little bit of relief there [Music] Bellissimo I love it so these guys can all live here isn't that lovely I got straight neural heavy I got straight neural public medium nope yeah that's it that's yeah so we'll go that's straight normal heavy that's medium that's light this is Diamond medium [Music] I have extras here I don't need them all which is fine oh right right circles all right [Music] that's it five extras there we are now ah are you kidding me it's bumping the forgot your Merchant Mercury all right so I'm just gonna take off about 250 thousandths off of the bottom of this thing let me use this same bit because it's plenty let's start with this end because that's the most delicate chunk foreign [Music] these big Milling bits are dangerous you should be careful around them I watched one of them take off the tip of someone's finger once I am very cognizant of their danger as I utilize them all right presumably that might be the last step all right same view different optimism you you lived out did I did I really do that did I somehow spill the extras I think I did that's insanity [Music] all right I'll find those I have many it goes there guys there and I believe there we go huh [Music] ladies and gentlemen ladies and Gentlemen please I'm very happy with this yes all right day by day inch by inch sorting drawer by sorting drawer by Mill and my lathe get more and more refined and more intuitive as tools that I use all the freaking time I am so happy about them thank you guys for joining me for this both tool tip Pro and tell and one day build a little bit of a little bit of Advent there's a lot of bending going on uh anyway I'm Adam and I will see you guys next time cheers
