  • Just so u know Its a dial indicator, and u always need to check to is everything till its square!! When you assemble everything there may be shavings oil etc between machined surfaces, a film of oil can be .001" then you may have shavings etc stuck to the oil which can continue to through everything out of alignment. But you won't know till you run a dial on the vise. It just depends on what you are building. Good luck. Ps millwright by trade

  • @BEERSHAREver01 I've had someone else correct that, but when I Google "test indicator", this device is what I see, and even the definition in dictionary and wikipedia speak of a test indicator having a lever as opposed to a standard dial indicator and that they read higher accuracy. What gives?

  • You should always "ALWAYS" do a check of accuracy on the vice straightness before machining "ALWAYS" I am a 25 yr machinist and this is so important. Square is Square!!!

  • ha ha ha

  • And where is the Trick?????

  • OMG! But what if someone turns your vice! :O It wont work then!!!!!!!!

  • Well done.

    Always a good feeling seeing someone create a "Down & Dirty" procedure hooking up their machine vise on the quick! Forget these knuckle heads commenting with thumbs down! Keep up the good work. SBB

  • КАК ЖЕ ВЫ ЛЮБИТЕ ПОПИЗДЕТЬ!

  • Pointless, shouldn't take you more than 3 or 4 trips back and forth across the vice to get it in.

  • @ems7218....Dude, what do you mean idiots? If you would look at the bottom of the vise, you would see it is already machined to be keyed. Before you start tossing out name calling, maybe you should learn a little more about machining and it's equipment. I was just giving a little constructive criticism and not out to bust someones balls. And if one is going to align a vise to a table in the manner shown, drop a 5/8" bar down into the slot of the table and clamp the vice to it. You're now aligned

  • Bridgeport vises come keyed for the X and the Y axis'...

  • A I stupid ???…

    I didn't understand a thing of how this vice is more easily aligned now !!!!…

  • @vincent7520 Because the key slots are square to the machine (or they should be) and now when he puts the vice on the table it sits snug into the keyways and is square straight away

  • @GeneralG1810 Oh !… OK. Got it !…

    Simple enough (must have been dumb when I watched …)

    Thank you !

  • @vincent7520 No prob I doubt your the only 1 who didnt know

  • DUDE There is already holes taped for 2 small rods inside the mounting holes all you have to do get a piece of stock drill and counterbore it

  • Hey dude thanks. Ignore the idiots. Its a time saver and I appreciate it.

  • thanks for the tip

  • Cool trick. It's amazing how simple tricks can save us time and money. I have decided to build my own lathe, not because of lack of money, but I will learn from each part I build. I just got a big peice of structural steel from school that I will use as the base. It is 10" x 47" and weighs about 60 or 70 lbs. I just need a good motor and buy the bearings I need, but I have enough scrap to build it.

  • Nice tip, thanks for that.

    Should point out though that it's obviously only as accurate as the initial lining up of the Alloy bar, so make sure that's spot-on.

  • Your looking right at the T-slot block holders by the bolt down holes,,,,what happened to those?

  • Roadracenut.....nice job of what you did, but totally unnecessary. If you look to the left and right of the center hole in the base, there is already keyway slots milled into the vise from the factory. If you have a Kurt Vise, you can go to Kurt's website and purchase two hardened keys that bolt right on. Or you can make the keys yourself.

  • @remiew45 Check out my video response to this video.

  • @remiew45 Ditto, to much work for something that's already been thought of and is incorporate in the vise already. I guess if it makes him happy than good deal!

  • umm how am I supposed to make space shuttle parts using this!! /sarcasm

  • vids like this ore are like the rain in the soil it makes to go out all the worms under XD haha only soil worms are useful and the ones here are self-made-smartasses-idiots XD hahaha

  • Wheres the trick?

  • Heres a tip, never clock up with a jacobs chuck , using collets!

  • al our vices comes equipped with such a heel already from the factory, but when it´s an accurate job(tollmaking) we always check with an indicator aswell, we learned the hard way, the t-slots get worned down. but as u state: great tip for the amateur.

  • What would it cost for a working used mill like this one?

    This is used like a hand crank cnc right?

  • Didn't you know that everyone's an expert on YouTube? lol. It's not like you're working from a high precision engineering workshop. Anyone watching this looking for tips sure as shit ain't either, so what do they expect...perfection? If the tip worked for you and helped someone else, that's all that matters. Thanks. :)

  • its even more fun trying to indicate when your just in a highschool class and the tooling is damaged most of the time... NOT lol

  • @ionmanpaintball You're lucky to have a high school shop class. When I was in high school they no longer offered the course.

  • @biguglycaprice Yeah, some twisted minds in higher govt decided to impose a "service related economy", and to discourage the local school boards from training the students to learn anything which is actually fun and useful, . . .

  • Awesome, We have a mill at work and a couple vises that need this so bad. I hate trying to square up, this really helps a lot.

  • Comment removed

  • Dude,....good clip....informative...and from another amature, appreciated. Ignore the negatives...

  • drill press

  • please buy a tripod. I'm seasick.

  • Can you explain this again in metric?

  • must see videos are seldom any good.

  • actually, you alredy had these. those 2 slots next to the holes that bolt the vice to the table should have keys bolted into them for this exact purpose.

  • It's called a tenente, locates your vice to square to the table... easy!!

  • Thanks for sharing - very interesting - I know what Im doing tomorrow.

  • ебло, кто же металическую стружку руками сметает, пускай даже алюминиевую

  • poor vice

  • Odd thing is, the vise already has the key way slot in it.

  • Wow, such commentary over something so simple. WHY would you want to set it up to 0.0001 if you don't have a climate controlled room to work in. Geez, just look at what he has to work with. It's not a modern preloaded ball screw machining centre just a shop floor milling machine. PERFECT for what he obviously wants to use to make things.

    Horses for courses boys and girls. It's a great little time saver and one I use myself. Keep up the videos. I like 'em.

  • stupid idea and it's called a dial indicator, not a test indicator.

  • @ebayisajoke It actually is a test indicator. They have dials.

  • @ebayisajoke They are actually called "dial test indicators"

  • .0001 is for grinding, lapping, honeing, If you're holding a one thou. tolarance on a milling machine, you're doing good.

  • @TheGeezerbiker

    Yeah, no shit.

  • Did the Test Indicator died?

  • Just use the indicator - that way you know you are right.

  • 1/2 a Thou is fine for most things - I only had a handful of parts where I needed to do better.

  • @newraysUtube I've been toolmaking for 47 years, and the last time any part actually had a tolerance of plus or minus .0001" was in 1966. I was making punches to cut paper and I certainly wasn't using a mill.

  • @winterka100 - oh, now, now; a lot of our internal components we used in petroleum valving manufacture were into the ten-thousandths...me thinks you fudge a bit, here. Might want to look into those companies around OKC that still make American-machined components, before you speak too loudly. Until the name-brand shock absorber company I worked for in the 90's moved to Mexico, we had some parts into the ten-millionths, on print and spec'd....mostly micro-hyd metering holes.

  • @MountainDweller67 I realise that what you say is true, though the tolerances that you mention are usually restricted to valving , pistons fuel injection pumps etc.I was referring to general machining and toolmaking (mainly plastic moulds and press tools). The main theme of my previous comment was directed at the guy who insists that mill vices should be set up within .0001"Over the years, he must have wasted hundreds of hours worth of his employer's money with his fetish.

  • @MountainDweller67 What a dude does in his garage shop and industrial production of high precision gear... Not really comparable.

  • Comment removed

  • @manofstl2000 Hmmmm....It could be that I was joking..don't you think?

  • I don't understand why you cut a new slot, they're already in the base, even drilled and tapped, on the center line. my 8" swivel vice even came with the dowels to place in them. there's another thing, it works just as well with a couple of dowel pins if you drill and ream holes, and a lot less work than doing it this way.

  • You don't even need to use a five eight piece of key-steel. If you use only three eight and pull the vice back towards yourself while clamping it down, it will still be rough-e-nuff for most stuff. And it's easier to pull off the table after you've finished. As long as the tee slot has clean edges/faces, it's fine.

  • Nice tip there, i sure hope you check it every time though. you cant assume it's perfect everytime.

    you assume and then you look like a dodgey machinist when it's wrong :)

  • Simple, easy to do, accurate.

    That is the way to go!

  • After reading most of the comments this simple video has generated, I came to realize what pedantic pains in the ass we machinists, toolmakers etc. are. I guess it's a case of "precisionitis" Arguing over the correct name of a slot for f***'s sake. Of course, the .0001" guy is the winner of the "Ass pain" award. This vice alignment project has ended being more complex than the Moon landing.All good fun!

  • @winterka100 I have enjoyed watching the comments this video had produced, but this one is my favorite!

  • @winterka100

    Forget it, Jake, it's Youtube.

    :)

  • @wackywankavator Like I said, it's all good fun!

  • Oooooh, shakey-cam.

  • @HenrikOlsen I know, it's a terrible video, sorry about that. See my video response to this, it's much better.

  • Recheck it when you change the jaws. 100 to 1 you will have to make new slot.

  • cool stuff.

  • @manofstl2000 poser

    

  • @manofstl2000 I invented machining.

  • Hey guys - check this out: google:

    lathes jr bentley

    third picture down - the tiny Taig that fits in your hand. check the whole site out

    Now check this out - go to modelengines info; his main site

    a broadcast engineer - not a machinist. This guy made a tiny t cutter out of a drill bit in 4 minutes.

    I work with lots of machinists here in DC... I'd put that guy up against most of them.

    Ya ought to see the tiny radial saws he made - really check out his site.

    Amazing...

  • it's kinda cool if you need to do a quick part where accuracy isn't too important.

  • Alumin-i-um.... fucking retarded american pronunciations.

  • @guitargenius1234 Try giving a little respect to the British chemist, Humphry Davy, who isolated the metal form and named it aluminum. 

  • @manofstl2000 And you are hitting that accuracy with a Bridgeport J head and a Kurt vise? ; )

  • I am an amateur as well and this is a very helpful tip. It's going to be a big time saver for me in my projects.

  • Im a machinist I also worked for Mitsui seiki installing,repairing, 5axis machines so they can machine to accuracy of 2microns . If this guy is happy about this let him enjoy his accomplishment . Some of us have unbelievable tolerance but let's not crack shots at the guy say good job post some more videos we like watching.

  • I am familiar with this tip, however I couldn't figure out how to hold the vice in place. As often the case the solution is amazingly simple. I plan on doing this on my own machine, I will probably buy some tool steel for the job as it's the only thing I can get that dimentionally accurate. I can't get imperial sized aluminium here and I have 5/8" slots. Thanks for the video it has made a difference.

  • @manofstl2000 your an idiot he called himself and amateur not a machinist....

  • @vutre4 You don't get to call anyone an idiot until you learn the difference between "your" and "you're"

  • @manofstl2000 you're an idiot

  • to be exact...0001 is one tenth of one thousandth...most machine parts are made with a tolerance of 0-5 thousandths + or -

  • noone can hit.0001..that's less tha one thousandth of an inch..you would have to have the most accurate machine on the planet....do you?

  • I did the same thing to my vice, except instead of the bar, I just used two neat fitting pins. As for .0001", a total wast of time.

  • @manofstl2000 Why would you waste time setting up to .0001" if it's not required for the job? Maybe you suffer from obsessive compulsive disorder.

  • What's funny is many milling machines only really have a repeatable accuracy of .001 due to problems with gibs, ball screws, casting imperfections etc. So, aiming for .0001 during alignment isn't going to do you any good. Great job with this rapid alignment tool! Looks good to this amateur machinist!

  • precision is great here, good job

  • @manofstl2000 , Real machinists don't call themselves machinists, others do. There's no reason to post a hateful comment on this video. Most of the work shops see is +/- .005 because of cost. Sure, we can all work out to four or even six with the right equipment and skill, but if his vice is indicated within half that's good enough for 90% of the work in the world. roadracenut, great video and usefull tip for many practical applications.

  • @manofstl2000 OK, I won't call myself a machinist, happy?

  • @roadracenut One more thing, Don't listen to "real" machinists, most of them are unreliable employees that call themselves journeymen when you hire them but when it's time to stop talking and start making chips they suddenly don't know anything. If you want to know if a guy is a journeymen or master machinist, ask to see his tools...if he doesn't have any or if his box or tools aren't clean, he's full of shit and isn't a machinist I'd hire. Stay safe and keep learning.

  • i dont get it

    

  • I have worked on molds built in Brazil, Japan, Taiwan, Hong Kong, France, Vietnam and India. Converting inch/mm is like breathing to me. Here in the states we have literaly millions of machines, mills, lathes, surface grinders etc.., that are calibrated in inch increments, that are not ready for the scrap yard. As new machines,Digital readouts, CNC come in we will be better able to make the switch. It's coming so relax and remember 0.03937.

  • Cool video and nice tip. I like your milling machine too. Thanks for posting.

  • Unless you have a bride port, running some cat collets, with balls screws in all axis, hand lapped table and vise and stuffed it in a temperature and humidity controlled room YOU ARE NOT GOING TO BE MAKING PARTS TO 1 TEN THOUSANDTHS OF AN INCH!... the typical manual milling machine is more then capable to repeat and produce within .002 of an inch. these morons chiming in talking about .0001 acc, need to go watch surface grinder videos.

    to the auth of the video, awesome tip, nice video!

  • How square is it? Is it within .0001 over 6 inches?

  • @ToxicZim Not even close. I have never needed to machine anything with that kind of accuracy. I figured I was doing good to even have a Brown & Sharp indicator, and it only reads to .0005. I shoot for .001. Not sure if you heard me mention it on the video, but I am an amateur and I just use this machine for fun. Hitting .0001 sounds like work to me.

  • @roadracenut with the right machine, coming within even .0002" is not outside the realm of possibilities. I do, however, have a slight problem with you calling it a 'keyway' when its really a slot or groove. A 'keyway' usually pertains to cuts made along the length of an ID or OD using a broach. just saying.

  • @vintageludwig I see your point and I probably should have called it a slot. However, Google keyway definition and see what Google is just saying! :)

  • @roadracenut I hear ya. I'm just getting picky over semantics. its all good.

  • @vintageludwig

    I'm a pro and we call that a "T-slot"

  • @zapwatt actually the T-slots are what are cut into the table. there is no undercut or "T" in the slot that he milled. and I'm a toolmaker, I also know what I am talking about.

  • @vintageludwig

    I am talking about the T-slots in the table.

  • @zapwatt nobody is disputing that. of course those are T-slots. he isnt even talking about the slots on the table, but the slot he milled on his vise.

  • @zapwatt I'd be more comfortable calling it a keyway than a T-slot...

  • i wish and hope America to convert to metric

  • @boomba3 Amen brother!

  • @boomba3 This idea of metric vs imperial is silliness. We're already there but we're hung up on words. Change your mind & mouth to use the words "fractional" & "decimal" instead, because that matters more. You can be metric and use fractions or you can still be imperial and use decimals which *drumroll* we do! It's simple; The next time you need to do something 10-1/4", just say 10.25" instead. Beyond that if you cannot multiply twelve then numbers are simply out of your league.

  • @boomba3 Why? Our method of measurement works just fine the way it is. No reason to fix something that isn't broken.

  • I'm sure that you understand that ideally the metric system is better (simpler).Having said that, Australia started converting to metric 35 years ago. Being a toolmaker, it was a nightmare.Half the drawings were metric,the rest, inches.I now happily use both,my machines are still in inches, but it's no big deal.Strangely, machinists and engineering type people never use centimetres (only millimetres) "outsiders"? only use centimetres.I think it will take another 20 years to get it smoothed out.

  • @winterka100 I use both systems with equal ease and am always amused when I quote a dimension in decimetres. Screws up our metric only guys royally. Even after 35 years of Metric, try walking into a meat shop in Oz or Canada and ask the young person behind the counter for a quarter kilo of sliced meat of some sort. That'll earn you a blank stare. Metricists, bear in mind that we machined in thousandths in Imperial. It was no great challenge.

  • @winterka100 So true I always speak in millimetres for most of my measurements

  • @boomba3 Me also!

  • @boomba3 Think this may take generations for them to learn....they still havnt mastered english yet !!!

  • @boomba3

    I like both the mm and Inches. I love math, decimals and fractions are easy. Metric is easy and i like to use it with bearings and shafts stuff like that. But i love fractions to decimals so i will never convert fully to metric.

  • @boomba3

    I hear you. Almost every project I do I measure in metric. My buddy uses SAE. It's hell when you go into the /64ths and smaller. WHY?!

  • with all due respect, isn't that a super super obvious way to handle the alignment?? I think most advanced machines have that embedded already...

  • an indicator is still more precise anyways. interapid indicators have more travel then the one you have.

  • A trick I discovered myself is to put ground dowle pins (2) in your tee slots in your table. They fit snugly, space them apart accordingly. This give you to contact points to which you can push a work piece up against thus getting it square in an instant. Then Clamp it to the table. It will usually be within .001-003 thousands over the whole piece length. you can then tap it in closer if you need to., I use dowel pins all the time.

  • TRIPOD

  • Great note, thanks for posting it and to the gentleman for pointing out the pre-existing one.

    The only thing I would add is you may want to make your key out of steel. If made from aluminum it may wear over time and change true.

  • @Rivett608 Thanks. I finally picked up a 5/8" steel key the other day, but now I'm thinking I'll look for a 11/16" piece instead!

  • The key slots for x & y on a kurt type vise are .688. All bridgeport type mills have .625 slots.

    Hardened steel step keys can be bought for $60 per set from MSC.

    Milling a slot at the back of the vise will not weaken it. Factoid: For every 1lb of pressure, it exerts 1/4lb down.

    Even if keyed, the vise should still be indicated in.

  • You will notice that the manufacturer put the locating slots in line with the mounting holes so you can use all your t slots to mount your vise. If you don't want to make stepped keys you could cut the .625 slot centered on the original slot and use a key that is short enough to fit between the mounting bolts. Also it is a good practice to use some scrap aluminum sheet to place under your step blocks when you are using strap clamps. Saves some wear and tear on the table. Nice work though!

  • If you look at the center of the vise, you will see a slot that is already prepared for the key way. In addition, you can purchase a pre made key for the appropriate vise slot/t-slot combination. As for the stresses there are none associated with this setup. Great job on the out of the box thinking. Keep it up and forget what everyone else thinks.

  • @rufusthecat289 Wow. Who knew? Obviously not me! Looks like they are $30 each. I'll have to decide if it's worth my time to buy two for the other axis or do the same again. I haven't had time to even look at the Bridgeport for months. Too busy with home improvement projects and young kids. Thanks for the comment.

  • what are you talking about....

  • That looks more like a drill press than a milling machine... o.O

  • THAT IS FREAKING GENIUS! Ok what did I just watch?? HAHA! JKJK!

  • @rocketman697

    If you bother to read the comments you will find that he stated that the slots on the bottom of the vise that you speak of, are:

    A) very shallow

    B) are .688 wide

    Thus he would have had to go to all the trouble to accurately machine stepped keys.

  • @applejak2000 You effectively reduce the strength an rigidity of the vice. Your ability to hold that back jaw square while tightening the vice is reduced... What is so much trouble about making stepped keys if you've got a milling machine?

  • @rocketman697 how would milling a 5/8 slot on the bottom, as he has done, reduce "your ability to hold that back jaw square while tightening the vice..." ? It has absolutely nothing to do with that. Secondly I seriously doubt that milling a 5/8 slot "effectively reduces the strength an rigidity of the vice. " -- appreciably, at any rate. Go ahead mill very thin stepped keys if you want. What a lunkhead! This trick has been used successfully many many times over the years.

  • @applejak2000 Well I won't turn this into a pissing contest, or resort to childish namecalling... I will only say that this is not how I would treat my vice.

  • @rocketman697 If the highest stress in the vise was at the bottom of the vise or it was exposed to a high bending stress, I would be concerned. As to the stepped key, it isn't a ton more work, the truth is since they were so shallow and wider, it didn't even register that that is what they are there for. You all have to understand, I am a total hack, and don't pretend to be a machinist. I have learned a ton from all of your comments and wish I had as much machining knowledge as you all do.

  • It seems to me you could mill a square bar about 10" long and place accurately centered extra long 5/8 dowel pins at each end. Clamp the bar in the vice with the pins extending down into the t-slot and tighten the vice body down to the table once you've got everything set. Since the pins are centered on the bar (exactly parallel to the longitudal axis of the bar) they are thus parallel to the fixed jaw once the bar is clamped - they thus will bring the fixed jaw into alignment with the t-slot.

  • Did you check it after it was finished and mounted?

  • @dave7222 Yes, believe it or not it was less than .001". Far better than I had hoped for.

  • It's good to have an Approximation ! My advice is to always have to Indicate, no matter what ! Is better work accurately !

  • i got another faster trick to get a vise withing 0.010 every time depending on how worn out your vise is!

    my trick involves 2- 5/8 solid dowels (not pull dowels)

    all you do is slip the dowels into the clamp slots of the vise and push the vise forward, then carefully remove the dowels, then place your clamping on loosely, pop your indicator in then tap it a bit 1 way or the other and tighten down! no need to make new slots or anything of that nature!

  • Very nice. Now, of course, if this level of accuracy is enough for you then you could have just placed the vice on the table and a ground rod in the tool holder and cranked the table back and forth with the vice jaw up against the ground rod. But still, this is a quick way to just attach the vice and clamp it down. I will say I'm not keen on 'cleaning up' the slots on the table since depending on the state of your gibs you run the risk of seriously maiming the table once and for all time.

  • @jimbrady1776 Thanks. Have you tried this and indicated it?  The trick in the video gives me less than .001" accuracy. As for milling the T-slots, my gibbs are in great shape and VERY little metal was removed.

  • @roadracenut Nope. Although you can accomplish the same thing by clamping a bar into the vise jaws with pins pointing downward to hit the T slot I prefer to use a pivot pin in one vise ear. Yes it takes more time but I'd rather take the time to be more accurate. To each his own.

  • THIS IS GOOD

  • So basically all you did was square up that aluminum so you can have your vice square upside down, then milled the keyslot, and then drilled/tapped that 5/8 bar to your vice so it would fit into your T slots so its square every time. Nice. While its good practice they make us indicate the vises every time we go too use the mills in our class.

  • What is so hard about indicating the vice and tapping it into place in relation to the spindle and head tram?

  • @OnionChang There's nothing hard about it, just time consuming and unnecessary for the kind of accuracy I need. I have far too many other priorities to spend my time indicating my vise every time.

  • Hey guys, just wondering, I starting training for Machining (CNC etc.) and I was wondering what you guys make so I can determine an average of what I'm getting into.

  • That really varies a lot depending on what part of the country you live in. Nobody likes to talk about pay but since I'm retired, I don't care anymore. I have seen people start at 10 to 12 bucks an hour or more depending on where you are and go up to 30 or more an hour. Good luck.

  • @Kingjames313

    you might start anywhere from $10.00 - $12.00 if you just get out of school and have no experience.

  • you should just mill your vise in half. I cut mine into little pieces and through it on the floor.

  • @shawnstam

    Through? 

  • @shawnstam I've done that but it just regenerated and now I have a dozen little vices running around my shop.

  • Not a bad idea actually, but I doubt my compnay would be too happy about me putting slots through the bottom of the vices!

  • @skateboard4zero There is no need to. The manufacturer thought of that already and put slots and tapped holes in the vice just for that purpose.

  • As you learn (as I did) you will come up with many little time saving tricks that will make your life SOOO much easier. If you have a workpiece that is tricky to position and/or clamp, take the time to make a fixture or jig. Doesn't have to be fancy or perfect, but as time goes on, you'll be glad you did. I was milling slots in steel tube, and each peice had to be custom setup. I made a fixture, and now each time I need it, I smile. Got that right here!

  • Yeah, nice work You make!!! But that "device" for vice is good, also that "device" is maked long time ago. It use for indexable heads and rotary tables etc drilling/milling equipment too.

  • Dude- put (2) 5/8 dowel pins in the key ways, flip the vise and grab the pins with the vise. mount your sacrificial bar (that's slightly proud of .625), Mill the bar to .6245/.6249 end to end. and that's how a pro does it. quick and accurate, and on to the business of business.

  • I find that pins are more accurate than keys at positioning anything on a jig,fixture or machine table. once you have the vice (or fixture) where you want it and have it aligned to the mill just drill and ream a pair of 1/4" holes for dowel pins. You can also set the vise at 45 or 30 or any position at all on the table and pin it in as many places as you want.
