Chamfering Block Build

[Music] welcome back doc stools this your first visit to my channel I'm Tom the host a little bit about myself I'm a lifelong metalworker avid tool collector tool maker and practitioner of most things mechanical during the day and my day job I work for a not very secret government lab making sure our research scientists have all the tools widgets and devices they need to do their work when I'm here at home in my own shop I'm trying to learn as much as I possibly can about a trade that's been very good to me part of that responsibility is that I share my skills knowledge and experience with folks like you watching these videos and along the way if I can preserve some of this knowledge for trade knowledge for future generations all the better so with that said let's see what we got going today all right so a lot of people picked up on this tool in the finale of the adjustable V blocks build so if you want to see this tool in action making some actual parts go check out that I think it's part 5 of the adjustable V blocks and what this is this is used for putting chancellors on small parts in the surface grinder so it's actually pretty cool and it's a pretty straightforward piece to make and what we're gonna do today is we're gonna make a kind of an alternative hybrid design of this that you guys that's pretty easy to make at home no heat treating and no grinding and if you make it all the way to the end of the video hopefully and they'll tell you how to get the plans for the hybrid okay let me actually let me show you the hybrid here so because it's done there's a hybrid so it's a plastic body with a cast iron foot on it to suck to the magnet cast irons really good on the magnet because it releases really easily so so anyway let's go let's go make one of these and then hang around to the end and hit that subscribe button and get some plans to make your own yours our raw materials for our hybrid chamfering block so in this case we're going to use a head this big thick chunk of black Delrin here this is a two inches thick and then and then you know a bandsaw out a chunk like that okay and it's nominally the right thing cuz we'll dust this off so it looks nice and then already is a piece of cast iron on the base here to provide our magnetic gription that we need for the magnet okay so let's stop some materials here and and get down to it huh what do you say [Music] cool this is one of the cool things about the marvel style saw is basically it's a powered vertical bandsaw so it's making a straight cut but with power feed so the whole head moves in your work stays stationary and this this tilts both directions too so it's kind of a fabricators dreams now this is a cast iron that we just sliced off here for the base of this chamfering fixture so you know it's rough it's rough sawn but we're just going to dust that off on the mill and thickness is a real important in this case but you know made some flat bar in a few minutes literally now what I've got going here this is a tap Pierce magnetic knee and since this piece is so narrow I just wanted something to square it nicely to the back jaw the vise so this actually worked pretty good and snapped right to that and I just clamped us because I didn't want it to move or you know because I'm a chicken and Bob's your uncle so let's let's get going on that [Music] [Music] [Music] [Music] [Music] [Music] a little more a little more bite ski there oh that's a better way to do a little bit of clean-up and squaring work here I guess I'm decided to use this flight that I haven't used it in a while mainly because my shear hog is in the is in the other machine I don't want to take it out right now so we're just gonna use this fly cutter which is gonna work using rapid traverse right now get to clean up and then I'll take a Finnish past let's say get cleaned up on now pretty good time I think maybe another pimp out and then beat slower they get a nice finish and we'll flip it 180 and we'll do this side make that parallel and we'll go ahead and bring it to size to normal size and then we'll stand it up and do the end services so a little tip when you got a block like this if you can bias it now this one there's not a problem because it's longer than the Vice right but if you have something that's as close to the length of the Vice or just inside the jaws sometimes it's handy to ship it off so you have a bias so that you can actually take a measurement really easily now this isn't the case on this one this one is you know nice so it's not really an issue what I care about at this point is get a cleanup and then I'll get a measurement okay so now I can certainly do it this way really they went for and a little over four in an eighth right now so I got plenty of material to I'm safe taking an eighth off without any issues so let's take fine actually I'm kind of out of I would say I'm a little rusty with with like cutters because I just haven't go on Tobias it's I have to eat all the chips that's a hundred thousands cut there and I'll slow it down when it comes off of here just starting to get a lot of edge break scrub measurements there this is all that's going to be caliper stuff here oh we got four inch 24 inch 28 thousand so I'm just gonna take that all on one whack see if we can let's see if we can make the woodchucks roll over in their piles of sawdust here with horror as a as a machinist uses one of their beloved tools right okay sweet all right so we're gonna square this up now so we're just gonna use a precision machinist square now it's you know it's nice they have a little bit of surface to put it in and this would probably be fine just to do it this way and off-center it but sometimes you don't have that choice so let's let's do this instead another way you can do it now clearly we can't and this is one of the the weaknesses of the curt vise here is it's got this this overhang here and you can't get right up to the side of it so other vices don't have that that issues just gonna put a little riser block on that get up as close as we can and then we're just gonna kind of come across to that let me give a little tension on there and then these squares are actually really good if you you know look if you sight it the light actually what I want to do is I'm gonna be that way a little bit that way I can tap into it like that and double check it to make sure that the square didn't move on you okay and then put some grok on it double check it again and I'm happy with that it's gonna leave this out cuz oh actually you know what we probably won't need that touch then quite clean up come back cleaned up I'm just gonna give it I don't know five or something like that and slow feet across it for penny [Applause] [Music] so I had about a hundred and seventy-seven thousands to come off of that I'm gonna go to one let's go to 170 [Applause] and he saw me going slow at the end there I don't want to break out a corner that's kind of why I was doing we got this kind of crummy stock surface on here and then pretty typically plastics are oversized and when we got two inch Oh a t4o 82-68 okay so it tapers a little bit so what we're gonna do is we're gonna plop it in there like that and this sticks up above the jaws nicely so actually plastic is so soft you know if you got any crud and the vise jaws well this kind of goes for anything you can you can put a dingus Magee in there that that really pisses you off later so let's do that and I'm not gonna smack that down because I'm going to create a nice flat surface there yeah and I'm just gonna touch on that I'm not gonna you see it scratched it so it's already in a little okay because it's get across there and get an initial kind of read on what what it looks like there looks like it's going to clean up just with that little a little light-skinned which is fine and since it's tapered I don't want to you know normally you would kind of balance both sides how much you're taking off so here I'm just gonna take about something that makes a nice cut fifteenth out something like that alright and then we'll flip it and we'll take the balance off of the the opposite side okay so yeah I guess I was thinking about cutting this notch out of here right now but I'm thinking I'm going back on that and maybe I probably should put all the holes in it these base holes to attach our chunky cast iron these Lightning holes here and let's see what else should I put the back pocket I think I want to wait on the back pocket because the depth of this exposes the gap here in the in this opening here and I want to kind of work the depth until I get the right opening there and I do that so I think I'm gonna go ahead and put all the holes in it now and and then we'll we'll knock out this this bit right here I'm just kind of anxious to do that so I gotta be careful so I don't like Bozo it and make it harder later on all right let's deeper this chunk of cast-iron psyche kiddin there's somebody out there that thought I was gonna do it look at doesn't that work good how do you like that [Music] [Music] [Music] hanging over a little bit so I'll go easy I mean I if I push on it I could see that flexing [Music] [Music] [Music] [Music] [Applause] there's a good use of the tweezers right [Music] all right this is one of those things you got to be a little bit careful with so this is a relatively brand-new Rhoda brooch here and these are just lightning holes you know and there's any number of ways you can put those in but this is just a quick way to do it and kind of in one shot and get a nice hole finish don't have to do it this way you can drill it you can bore it you cannot even put them in if you don't want them now that said these are very very sharp and they tend to be grabby and plastic so just beware if you're using Rhoda brooches on on on plastic so we're going to use the old we're going to crank up with the knee and bring the knee up so we got you know our feet is kind of locked in make sure yeah I'm in position and I'm all good to go so wish me luck and we're we're going pretty slow because I don't want to melt the plastic so better to go a little slow so let's get it started so far so good mice is tiny so I'll probably do this in a couple of while packs here just so I can clear the chips it's going pretty good I'm worried that the the tool is heating up the [Music] here like that and then I'll just pack this up we got lots of quill travel but okay alright so clear the chips I'm gonna go back find the bottom of the hole come up just a little bit walk and go back two big fat packs [Music] [Applause] and Bob's your uncle all right and then we get a big fat slug in there oh and that's the the bit of in fact see that okay all right cool all right so we got a nice finish nice round hole and you know that's a pretty quick way to get a inch and a quarter hole through there so I think we're close to the fun part now I think you're what I'm calling the fun part I'm just gonna mark this cut out and then go to town on the mill and you know chop all this stuff out of there with an end mill and then start taking some measurements okay all right so what we're gonna do it we're gonna set it up in the in the vise like that at a 45 and then we get this use an end mill and we do both walls at the same time all right so our insert jaws here so I don't have to take out the hard jaws because I've tapped the inside of that mounting screw so I can just map these on here you know it the first simple 45 stuff so I'm gonna go ahead and snug let's see let's make sure I'm you know these got they have a little bit of wiggle so I like to be in the middle of the of the wiggle if you know what I mean middle of the wiggle and then what I do is float the other one to align and now these are real deep you can see that right so that you get the maximum kind of the maximum amount in the in the vise all right so those are close it's still got a wiggle know what we're gonna do is plug that little Mickey in there like that look at that oh that's sweet or wet okay and you see that shift it's shifted to kind of a line up with a line up a line with the world that's not a word come okay I'll just go ahead and put a little drunk on that the other one there yeah like so okay that's pretty good setup so I'm just gonna mill through the lines and and then what I'll do is I'll measure from I have a dimension from that corner that intersection to there and I'll this kind of go by that we're gonna cut this our 45-degree notch or a 90-degree notch over there at a 45 I kind of pause there for a second and I started considering whether or not I should do this relief this back cut first you know while it's still kind of a square block so you know you could go either way on this it does get considerably weaker once you once you cut this out of there I guess the point that I want to make is you know before you remove material like that think about the next step and the step after that and make sure you're not working yourself into a corner now I'm pretty confident that I'm not working myself into a corner because I can hold it like this in the vise and I can still take this material out of here without any problem and it's plastic so not a big deal so I'm not super worried about it I see a way clear and I got a good flat reference surface and all that register again so I'm not real worried about it I get and I just want to make the point of think about your next two steps ahead kind of like playing chess a little bit [Applause] [Music] [Applause] [Applause] that's pretty close to the line there and we'll start taking some measurements let's go ahead and power feed that and then what I can do while its power feeding is just keep the chips off of the for the now this is just a relief so sharp corner parts can actually fit up all the way into that corner all right so we're all set up here to cut out this back pocket which is almost the last step here okay and that's 645 is my number so I'm gonna whittle away at this thing and carefully here very carefully a lot care go ahead and put it together so this in plastic this old this little leftover piece wanted to vibrate a little bit so I get not the greatest finish right there but it's not that bad either so I might you know if I was making more of these I might thicken this a little bit or thicken these sides a little bit just to add a little more mass to that just to stabilize it a little bit but I think it's it's fine for for what we're doing here so let's put this thing together and let's go try it what do you say we'll go set up the surface grinder and I'll find some some pesky parts that need chamfers on and then we will bust some champers on on said parts okay so we're kind of getting close to ready here so just so you know I dress the root the side of the wheel vert off so that it's parallel so we have a nice smooth surface and now I'm spacing this off the back rail I'm gonna leave it unmagnetized until I get down you know I dropped the wheel down so let's just let's do that rough Center eyeball there and I only really need the wheel to drop below the you know this edge here and I'm gonna come in get nice and close and then I'm gonna even up these gaps on either side so that I'm centralised then I'm gonna put them in a go okay we're pretty pretty sturdy and then I have a block handy just yet but what we can do let's get an idea here this has a chamfer on it already right so you can kind of preset so it's just touching there so I'm gonna back it up a little bit and then make sure I'm not rubbing anything and let me go find a let me go find a couple of victim blocks and then we'll we'll buzz them and see what they look like [Music] try I got a little piece of steel here behave yourself there's a nice little chamfer oh yeah it's beautiful so it's disease warning [Music] now that has a burr on it so it's actually shaving a little bit of plastic off of there so that's you got to be a little public I didn't bother to deburr this piece before I before I did it [Music] they do these vertical edges here and all this is it's just so that it squares this up so hopefully you can see that pretty well those are pretty sweet chamfers look so this I'm going to do these first time okay and then we'll do these and it's quite controllable now why did that one that's interesting why did that one oh you know what maybe there's that one that was a little heavier I don't know why huh maybe the piece is both I mean I was pushing on it pretty good but no I guess it looks the same okay I know I'm just psyching myself out here all right well I ran out of the edges there let's increase a little bit I'm going to increase the chamfer yep and if you've ever had to do a lot of champers I'll tell you this saves you a bunch of time there okay pretty cool huh and pretty easy to make so let's so remember we did cast iron and what was the reason because they release from the magnet really good so we're on there good now we just release and then I mean no fuss no muss right it just pops off okay that's one of the really really nice things about cast iron so alright that's about it for today I've had enough so this came out pretty good it works pretty good as you saw now here's the question I really don't need two of these so I'm looking for suggestions what I should do with this one should i raffle it off have a mystery question have a sealed bid or a silent auction the support channel support thing or something like that and we throw some up in the comments let me know what you think if you guys want to crack at this thing or whatever let me know so put it in the comments and for those of you that want the plans okay just shoot me an email and I'd be happy to send you a PDF of the plans okay and you can make your own your own hybrid chamfer block okay hey thanks for
