Shoot'n The Poop #2 - Import Vise VA4

if you caught the last video you remember I just gotten to 4-inch import vice maybe you'd like to stick around and talk about it I actually bought this slice for the CNC router but before we get into that I just want to take a moment to thank the kind viewers who inquired about my mill now I'm not gonna stand here and lie to you hard not having a mill I haven't found a replacement I like just yet but I do appreciate you asking flowers and the fruit baskets were especially nice my wife also thanks you and she wanted me to let you know that getting another mill in here has become her number one priority okay the vise this is a vertex 4 inch milling machine vise I only unpacked it about a week ago I haven't even bothered to get all the ear wax off of it yet as you can see this is an egg fixed vise which in my opinion has the advantage over an angle off ice in that when you're working it makes it a bit easier to maneuver around patent infringement issues now this isn't going to be an import bashing video about how upset I am that I didn't get a brand new Curt equivalent for less than $100 I knew exactly what I was getting into when I bought this I really had no intention of making a video about this thing or doing anything with it at all other than throwing it on sea and seabed and putting it to work but check out what this place came with the quality report a test report for precision machine vise I don't know about you but I see something like this and it's just begging to get checked out let's see if it's true good for a 2 horsepower I got my warranty card you read that it specifically states right there don't put in a vise you you if you own a robot be sure to take full advantage of it you know before the tables turn it did pretty good job so let's have a look at this test report get it to the VA floor and it looks like this thing's about three years old at least it was tested three years ago so at first blush those numbers look pretty good this in millimeters that's what four tenths on parallelism four tents on squareness and four and it's six tenths on jaw plate parallelism but note this is per 100 millimeters so this number is good every four inches or so aren't these thing is usually written in by hand I suppose they just print thousands of these and just match the certificate up to the appropriate advice you'll notice there's no real serial number or anything to attach this report to this specific vise so I assume they just make a thousand of these and then just sort them according to how well they happen to have turned out and match that up with one of these circuits let's check this first one out this one's easy parallelism from bottom of bed to running surface over 100 millimeters that should be 4/10 if I measure the longest distance here well let's give them the benefit the doubt let's say that's to the start of the fixed jaw we'll call that 250 millimeters so that's two and a half times that four tenths you know to stay within this json' grade that comes out to what one 1000 ism between these top surfaces in the bottom surface so I don't know about you folks but I find my surface plate to be a great place to keep my you know my cell phone and my car keys and my spare change bear with me just a moment while I get all the lemon soda off of this thing so I tried to swipe this down as best I could and just blew it off the air compressor so the bottom of this doesn't seem exceedingly flat this isn't very scientific but you tend to get to know your surface plate and what really flat parts feel like maybe we'll blew it just to get a look at the bottom so I don't believe my eyes bring it for a closer look I was not expecting that that's a half now indicator I think I'm gonna have to break out the tenths indicator what I don't know what to say I'm speechless I mean you saw that it looks like this sides a little high but within each rail I'm getting essentially zero indicator movement see if we can check the height difference between those two so that's zero that's what two three tenths we've got a camera between me and the indicator there this surface does have a little bit of a lean in towards the center this one looks pretty good it would be nice to have some way to bolt this thing down if you can imagine bolting this to the surface plate and repeating these measurements with the base of this vise you know pulled down to the surface let's blow up the plate and just see how that surface looks this is just some Prussian blue they've got a wee bit of acetone down there I just want to thin this out all right so the acetone did nothing at all and I switched to mineral spirits all right look like some kind of chemist here so this is always a little bit tricky for me if if you don't get just the thinnest of layers of blue on there meaning if you lay it on thick in any particular area reading the tea leaves gets a little complicated for kicks I'm hitting the top side too I know how well you can see that on camera there are low spots right in here a couple smaller islands I mean I'm no cartographer but it doesn't look too bad I mean a large unsupported spot here but we've got full contact on both sides right where the bolts go see what the other side looks like I mean I should have reblued the plate but again for how thin the blue is and when I paid for this I don't know if I complain all right let's try the next one we're looking at squareness front jaw plate two body running surface now I'm starting to second-guess myself on what this actually means all right so I'm pretty sure they mean the squareness of the jaw to this top service for a second there I thought they were talking about squareness to the length but what would that even mean I mean you can tram device in I thought perhaps they were talking about some kind of you know alignment to the key slots below it or that key in the back but I'm going to go with this that seems to make sense bear with me I haven't had lunch yet so we use my indicator to measure how square this is first I want to get it set up but have a lot of height to work with here I just want to get this set up some within range okay scratch that I couldn't get this indicator low enough without fouling the body of the surface gauge so I broke out a smaller one my smaller one doesn't have a bumper like the larger one does so I'm just gonna use a little ball bearing Nesta just sort of in that crotch there I think everybody knows the drill here I'm just going to use that as a bumper and zero my indicator up against the known square surface now as my reference square square be honest I have no idea you've got to draw a line in the sand somewhere can't go through life having trust issues I suppose I could have used my other surface gauge and just put like a 1-2-3 block or a gauge block in there but I think the less you introduce into a setup like this better so I'm reading 4/10 let's try the other side I can't get in everywhere obviously because of this Hollow and the size of the surface gauge I've got about five tenths here I want to just recheck this eye to make sure I'm not dropping into that countersink for the draw mounting screws in about four to five it's going to recheck this and make sure I've been bumped anything around it's about a tenth sigh yeah three to four tenths is what I call this thing it's a three to five just to keep me honest this is an evil surface gauge but the adjustments aren't as fluid as they are on the starett I think this might be a brown and sharp I mean it's really nice and handy to have again it's just not as fluid maybe just because I don't use it as much alright so this is actually measuring worse than what the certificate the test report says we were matching the four tenths but according to this piece of paper that's over 100 millimeters then we were probably over 20 so you'd have to multiply our number by five you could do the maths there sorry I hate that word when people say Matt's little pet peeve of mine I'm not saying it's not correct I suppose mathematics is mathematics plural and there's an S on it for the record I think the plural of math is math I mean if you were going to do a lot of additions you wouldn't call it ads would you you'd say add I've got a lot of add too that sounds perfectly normal anyway last one parallelism when clamping gauge block to draw plate parallelism and that's the worst one of course you know depending on the tolerances they have in their whole egg fixed geometry to keep those draws down in parallel or parallel when they're down see if we can figure out a way to measure that you know what new day new perspective I started to wonder if maybe I didn't do is create a job as I could have cleaning up under here before I put this fixed jaw in place so I thought I'd have a look maybe D bar this key and try this squareness measurement again probably can't see it in that view but I've also raised the indicator up as far as I could so I'm measuring the total height of the jaw and I've just reezy rode if you can't read that that's zero and then swinging either way it falls off that's 6/10 again six 7/10 this is seven and this is six so those are about the same numbers we were getting before I mean we were in the three to four and now we're up to six to seven but we are also kind of 20-30 percent higher up on the job and now I'm just curious what the source of that error is I'm going to stone these two surfaces and check the thickness of this Jotham micrometer see if I can't get an idea of where that's coming from okay so here's what's happening the fixed jaw checks out it's actually pretty darn good it's parallel and flat and the error seems to be coming from the supporting block for the fixed jaw on the back there's the five five and a half tenths and by the time it comes up another two hundred thousand tenths so I'd suppose the question now is can I find where that source of error is coming from and can I fix it and maybe if it's worth it or not I usually try not to ask those kind of questions so this is the support for the fixed jaw there's the slot that keys into the body of the vise and this is the surface we just measure as being is participating in the out of squareness so now I've actually already measured this and these two sides are flat and parallel so the only thing that leaves now is this bottom face that clamps up against the body of the vise all right well that's kind of a bummer and that this part checks out perfect I was hoping it was here since the two adjacent faces are really nice it would have been a cakewalk do you slow this on the grinder and clean up this surface but you know what I think it is recall when we blew the top I think we had a low spot up in this corner off to go back through and have a look at the footage so when the fixed jaw gets clamped on its pulled out of square by that surface on the vise body that also explains why we were getting two different readings from one side to the other we were consistently getting a tenth or two further out of square on this side so I put the vise back together and given that we're out of speck on to here on the squareness I don't think I'm even going to bother with the parallelism between the two jaws I'm just going to do a couple of final touchy-feely sorta tests this is probably one of my best one two three blocks I'm not really going to tighten this just uh that's pretty good part of me was expecting this side to pull up and the other thing I'd like to try is to check out just how much this movable jaw will lift looks like an get that to move about a half of that the front moves the same amount what does that mean you you so I think that does it for this video and I mean my apologies I really was expecting this to turn into a bit of a small project I thought maybe we do some grinding and some measuring heck I even entertained scraping this in but I'm quite surprised with how this turned out you guys saw the numbers it didn't hit the spec sheet but for what I'm doing with it for something around 150 dollars I think things turned out pretty well if this were a six inch or maybe for a larger milling machine let's say a primary milling machine I'd probably go the extra mile and try to get the small errors we saw out of this like I said for what it's going to be doing I think I'm going to leave well enough alone so again I apologize this didn't turn into a project I guess I just struck out with this vise just put this up as a short shooting the poop installment thanks for watching you

I'm into woodworking where if you can dial things in by +/- 0.5mm your doing pretty good. I really like these machining videos where the tolerances are like +/- 0.0001" or better. Such skook!

This guy needs more subs. He's like AvE meets Steffan Gotswhatever.

Haha. It specifically says right there don't put your **** in a vice.
