A lot of these videos are quite old but still and always will be relevant. Thank you for showing all your tricks. To be honest, I think I got a better education on KZbin than I could have gotten at any course I could have taken. KZbin has turned into a bunch of snowflakes the last few years, yet is SUCH a valuable tool to learn and educate yourself. KZbin is ONLY valuable because of content creators such as yourself. Thank you so much Joe. I bought the machines, never having laid a hand on one in my life. Now I'm making parts for a customer and have paid for my machines many times over just from him alone. I even built my own rotary phase converter using KZbin and practical machinist forum. I can't say enough how much I've learned from you and other machinists online. Take care buddy.

I cannot believe I have not come across your channel before, just seen it in the past few days and I must say your videos are fantastic! I love watching machinists and learning about machining on youtube, but some of the others can be quite.... wordy. You get to the business, show what is needed and not a bit more! That is the way to do it! You don't let interruptions stop you, and you don't even mention them, just pause, start again and keep going, you do not waist a second! You give enough information that even a beginner can understand the concept, but can educate even those with experience. Thank you for your videos, you are doing an amazing job!

Thanks for this Joe! It took me about two hours to actually get it to work. But I am rank green hobbyist with used Taiwan lathe and have been teaching myself. It has been a struggle , moving my lathe and setting it up on my back patio , wiring it , tramming it , leveling it and tramming it again. Crashing it , rebuilding it , bearings, tramming it again . Making it run true has been a big learning curve but I keep on keeping on! After shimming the closest my three jaw chuck has been about .009 and I am thrilled. Now with your collet/bushing trick I have repeated consistiently .003 everytime with my rudimentary and very limited tooling. Occasionally I have measured .001 surely the tolerances of my measurements have alot to do with just how precise I can consistiently achieve. I have bushings for 1" , .875 , .500 and .257" Just to get repeatability at this tolerance has been a major step forward. It is a painstakingly slow process but now that I have the bushings made the setup moves right along it my production of simple parts

[@joepie221]

Hi Dan. I see many of our internet guys run the spindle with a chuck without a part in it. The scroll is a ring with a helical groove in it that sits freely in the chuck body. There is nothing to stop it from spinning at a different rate than the spindle if there is no load on it. Take all your jaws out some day and start and stop your machine. This scroll has a mind of its own and could easily launch or trap the chuck jaws causing injury or damage. Its just not a good practice to spin an empty chuck. Good question.

G'day from Australia Joe, I'm a 60yo machinist(semi retired) and just discovered your channel yesterday. Your micro wrench ("spanner" in Aus) caught my attention and have since watched every single vid on your mini lathe build....absolutely loved every one (subscribed)....you, my friend are an absolute craftsman! I"ve been using this old (sacrificial collet) trick for many years and still do when i couldn't be bothered putting my 4 jaw up or if i want to quickly machine multiple components (i also make lots of parts for models etc and my 3 jaw is less than perfect). The reason for this comment is i simply can't believe how many remarks you get from armchair experts! As usual, people like this usually show just how limited their expertise really is, judging from their ridiculous comments!!! It makes me furious and i'm sure it probably angers you too. I really don't know why you even bother wasting your time responding to these morons! I guess you're just too nice...lol.

[@bobcatt2294]

At 2:48 you place on the screen, "Never turn on your machine on if the chuck is empty." I would like to ask why and secondly, even if the chuck is in the closed position (all jaws touching) this rule still applies?

[@faurana]

the reasoning behind this rule is that in the unlocked state, the chuck and all it's internal mechanisms are more or less free floating. so if you turn on your machine, nothing stops the internal screws from rattling around, and since there's a centrifugal force on the screwing mechanism, the movement will generally be towards unscrewing the jaws. give this enough time and you turn your chuck into a shotgun. adding onto that, at one place I worked at they had special "quick set" chucks that allowed you to jump the jaws between indexed positions in the unlocked state by just pulling on the jaws. spinning up one of those chucks without a part in it would turn shotgun even faster.

[@burtvincent1278]

Oh. Makes sense. I wanted to ask the same question since I do it on my old Sebastian lathe all the time. Guess I never noticed it listening up.

[@faurana]

@@burtvincent1278 if your chuck is all the way down for relatively small parts it's "fine" in the sense that you'd probably notice the yaws walking all the way off, but because you can shotgun yourself with chuck yaws (and someone probably did at one point, just like people shotgun themselfes with chuck keys every once in a while) people wrote the rule into existence.

[@sjaakhosters419]

This is a typical solution for a handy man with ample of time. As a pro I prefer to use an independent 4-jaw chuck. Even then I can put a small three-jaw chuck into the i-4-j-c. Always keep the chuck nice and clean, don't clamp too hard and use the same key hole (mark it). Also i use small strips of thin copper to get the work-piece within 0,05mm. But I work at a shipyard with big lathes up to 4,5 meters diameter and 18 meters length and we have no large series to produce.

[@joepie221]

Gotta say, In all my years of machining, I never saw another guy in any shop I've ever worked in, put round stock in a 4 jaw chuck. He would have been laughed out of the shop then fired. Your type of large diameter work is another world. You have my respect. This fix is good for guys that don't have a full shop of accessories to lean on and need that second side to run true. Thanks for the comment.

[@silver965]

Hey joe, wonderful video! out of curiosity, why would you never put round stock in a 4 jaw chuck? Is it due to just being a time waster in a job shop?

[@jubbaronny]

Joe Pieczynski For the last 4 years, I've barely used a 3 jaw and clocked all round bar in a 4 jaw. When you've done it as often as I have, then it's nearly as quick. I should mention the 4 jaw is 30" Dia and fixed using 8 x M20 cap heads and changing over is a job in itself using the 5 tonne overhead crane. Also I do a lot of none round work. I've been a turner, both manual and cnc for 30 years.

[@jermainerace4156]

If I had an existing piece of round stock that was already to size, and that diameter had to be true to less than 5 tenths with relation to what I was going to cut, I wouldn't' have any choice but to put it in an independent chuck. Even a collet might have too much runout for some classes of work.

[@joepie221]

My days with those big machines are well in my past. I too would want as many jaws a possible on parts that big. Thank God for overhead cranes.

Even if your 3 jaw is not out of wack this is a good technique to use when you want to avoid jaw marks. It’s like making a homemade collet out of a 3 jaw. I guess you could make a whole set of these “collets”...

[@jimphillips8774]

Cal30m1 Is correct , after high school in late 1970s worked in machine shop , superior air products ,Sayreville NJ ,we made brass collets to compensate our very worn old three jaws , a large brass collet was used to hold hex stock ,preventing damage to stock being machined .

Yup. Lots of people bitching about this needlessly. 'waste of time!" "Buy soft jaws!" "Buy a better chuck!" "Buy a better lathe since yours is obviously shit if there's that much run-out!"

Anyone can flip a switch and turn a wheel. It's the setup and technique that makes the machinist.

[@shirothehero0609]

@cjhills how bout those of us that don't have a collet chuck? How bout when you don't have the specific collet on hand and are in a pinch and can't order one fast enough? It has nothing to do with money or the price of a collet. This is a clever solution to a real potential shop problem. Not everyone has the luxury of having ample time to buy a collet for an operation when it comes up.

Joe, I'm real new at this. You are a real Pro but it looks to me like you take a lot of chances with Safety. All I could picture was that flat file getting caught on one of the jaws of the chuck and flying back at you. All it looks like is one little slip. Another was the band saw. You have the work piece material close to that moving blade, unstable, as you're adjusting the table, bouncing around the material about to touch the blade and send that across the shop. Or through your head. I may be a dumb Carpenter turned Welder now, but you're scaring the shit out of me. I appreciate all your great videos and learn a lot.

In a professional shop, time Is everything! Making fixtures is sometimes necessary for production runs..Having a quality adjustable 3 jaw chuck saves time and money! However, if you know how to properly use a 4 jaw Chuck you can indicate anything very quickly including eccentrics without all the fooling around! Not to mention a 4 Jaw chuck has MUCH more holding power! That being said, using soft jaws works well and is much faster and repeatable. It all comes down to set up efficiency, repeatability and production! Which means time and money! A junk chuck ends up in the scrap pile! No time for fooling around in the professional world.

And, they taught me their "way". I got out, only to hear, that because the "Navy" taught me, I wasn't commercially viable. So much for a veteran's skills being marketable in the civilian world... I ended up at a company called A&A machine, in LaMarque, Texas... And this was pretty typical of their machines. I spent 8 years there, until they couldn't teach me any more, and then I moved on to Conhagen... And the process started again. 25 yrs later, I'm teaching engineers. But, I miss the shop days. I've watched several of your videos, and you have pretty much covered everything that I learned from the "old hands" there. The difference is, you've covered it in a matter of hours. It took me, several years, to pry all of these secrets out of all of those guys. If you ever need another "old school" machinist, let me know. I'm in Austin now....

Boy! This brings back a lot of memories when I used to report to "Machine Shop" class so I could reserve my favorite lathe. Got a job at a huge company as an electrician but they did not allow me to use a lathe or even touch it except at times when I have to do electrical maintenance/repair.

[@joepie221]

I was a shop junkie in school. I was very fortunate to attend middle and high schools that had fully equipped shops and offered an industrial prep curriculum. Fell in love with the trade from day one.

[@noelguerrero2770]

The machine shop class was part of the Engineering Degree I was pursuing (4 semesters of machine shop) and enjoyed every minute of it. It was a decently equipped shop with only one milling machine. Everything is manual. Got bogged down in university when advanced math came up. Should have concentrated on what we call "Vocational School".

[@questioneverything1742]

This trick works great been using it for years running 6mm drill rod in a 40 year old causing lathe. Concentricity has stayed within .002 thru thousands of parts.

[@joepie221]

It really does. Just don't let the collar slip when you remove the part and you're golden all day long.

[@tylerjones6043]

I'd just get a four jaw, save the time get a .0005 indicator and be done with it....

[@glennedward2201]

4 jaw is a pain if your running multi parts back to back. Also some of us use various chucks for different jobs I.e: a 5c collet chuck, backing plate, etc.. and cannot limit ourselves to a single chuck due to the wide variety of parts we make. I have parts you could never make in a 4 jaw.

[@SuperAWaC]

@@glennedward2201 i guarantee i can make any of your parts in a 4 jaw

[@glennedward2201]

SuperAWaC i guarantee you cant and it wouldn’t be prudent to make some of my parts in a 4 jaw. To guarantee something you haven’t a clue about what parts I run is pretentious at best. Glad your such a stellar machinist. Fact of the matter I could probably produce parts twice as fast as the average machinist and we do small run production so yes we use multiple jaw chucks however a 4 jaw adds a significant amount of overall time to dial in the part and that is the point I made. Nothing to do with whether a four jaw or 6 jaw cannot be used however I’d like to see a right angle chucked up in a 4 jaw, lol, good luck. There is no way you can make all of my parts back to back using a 4 jaw and starting with material that is already .0005 in tolerance. You have no extra material so you’d better indicate every time you chuck a part. With 3 jaws I don’t have to do that. Also we’re more apt to use a 5c collet before a 4 jaw and I will take that for repeatability any day over a 4 jaw as well it results in quick changeovers and speedy production. I’ve had machinists with a so-called 30years come in and chuck up 4 jaws to turn around and have to pull it for parts that won’t center due to geometry that doesn’t work with 4 jaws. Then I watch them spend an 8 hour shift making an $85 part that I can make 15 in the same time. Some of these KZbin videos I see a 3-4 hour edited video and for parts that should take 10 minutes. It’s screwing around and wasting time. Much better ways to remain productive and that is to (Understand “Manual” production) and the use of “proper tooling” which is the key to a successful small business. Good luck with your approach.

[@SuperAWaC]

@@glennedward2201 i can indeed chuck right angles into 4 jaw chucks. i'm not saying it's practical, but it is certainly doable. i personally use a 4 jaw and a 6 jaw in my shop, i've never needed anything else. although i have modified my 4 jaw to be able to do weird things.

[@billsixx]

A better tip on using a file on a running lathe - Never apply a file against the advancing side of the workpiece (aka top), apply the file against the retreating side, (aka bottom). This way, if anything grabs the file, it will be shot out AWAY from you instead of driving the file into your hand or chest. Also, never change the tool holders while the lathe is running. If you drop the tool holder it could bounce right into the chuck and crash your ways, your chuck or your face. Power equipment has no conscience and no remorse over wrecking your body.

[@joepie221]

Everybody works the way they are comfortable doing, but I have to comment on your suggestions. Only if the tip of the file comes in contact with the jaws is there a potential for it to launch into your chest. Otherwise, it just bounces around and doesn't do anything. Chances are, if the file hits the jaws, it abruptly scares the shit out of you, and you naturally pull away. Working on the top of your work piece keeps the file in the rejection zone, to place anything under a spinning part is a really bad idea. Plus, it usually translates to only one hand on the file. As for shutting the machine off every tool change, thats a good way to burn up your machine or get fired. Back the carriage away to a safe distance away from a spinning chuck and use tool post knobs on your blocks for a better grip. I agree machinery has no conscience and only the operator is responsible for their own safety.

[@donking6527]

billsixx ,bill just use common sense ,as a machinist you should alwAys know what can happen,I've been a machinist for many years ,never been hurt never really screwed up,if you have to turn off the spindle just to change the tool ,then it sounds like your pretty careless,you must make alot of little stupid mistakes,professionals like me and this guy in this video ,rarely make mistakes we rarely do stupid shit like dropping a tool into the spindle,if your that careless you shouldn't be around this type of machinery

[@bogdan_n]

So you practically made a sacrificial collet. Huh. I'll put that in my box of tricks.

[@joepie221]

Cheap and relatively quick.

[@TimothyGambino9085]

Never file with your left arm over the spinning chuck. Always hold the file with your left hand. And it takes longer to make this home collet then to machine the part.

[@joepie221]

Wanna race and find out?

[@TimothyGambino9085]

Joe Pieczynski well at least you will have your legs for said race.. If a chuck is out that far something is wrong . Loading up soft jaws and boring them while restrained will win the race! Industry Standards

[@joepie221]

@@TimothyGambino9085 I appreciate your comments, but this video isn't made for shops with soft jaws and 2 piece jaws. Its made for the garage, hobby shop machinist that doesn't have a fat checkbook or a shelf full of attachments for his machinery. It clearly demonstrates, even with a severely out of concentricity POS chuck, you can get a part to run true. This bushing is a 5 minute job at best and is much faster than setting up and boring soft jaws. Legs or not.

[@rayocaballo6122]

Joe what is that indicator holder your using

[@Turbogto_guy]

DO NOT EVER EVER EVER file a part with the chuck turning towards you, in the direction that if the chuck grabs it, it will throw it at you. Always turn the other way. I was doing this once and it caught the file and slung it at me. I was lucky it didn't hit me. Very unsafe.

[@joepie221]

Filing a part with the chuck turning away from you has a better tendency to have you follow the file away leading you into a spinning chuck. Equally as dangerous.

[@mfx1]

So you basically made a poor mans collet chuck.

[@Stefan_Boerjesson]

Hi Joe! This video is a lesson on a very high level. You have a high level of knowledge and tons of experience. I have nothing of that, being new in this trade. I try to use my new lathe, not known run out, to do things. Grabbing the stock and doing as much work as possible ought to make those surfaces concentric etc.. It will take a lot of learning, gaining experience, before I try something like You show up. As I understand You were criticized for changing tools when the chuck was spinning, probably at the time 17:45. Watching Your video out of the safety perspective, looking only at Your hands, knowing Your experience, I see nothing wrong. Being a newbie I naturly stop the spindle . Compare with my "riscy" doing, entering the small windowless bathroom shouver I bring a low profile living candle, then swinging the morning grown up on its hanger, on a safe distance, remebering the candle, then bringing down the large towel not so faar from the candle. Every firefighter would scream out. Compare this, and Your video Joe, with driving a car. You need to place Your foot on the proper pedal, clutch, brake or accelerator without any mistake. Knowing the terms, having the experience, knowing the riscs, being focused it can be done safely. You can't be accused for being careless, negligant…. Several other Tubers could..

[@Farmersamm]

Uh..........what's the point???? Anything you put in a 3 jaw will machine true because the lathe axis is true. Move the part to another machine, or just remove it, and reposition it..................and you're F'd. By the time you mess around with the fancy collet, you coulda put the part in a 4 jaw. LOL. Click bait.

[@joepie221]

Actually not. Chuck jaws can be worn and therefore translate eccentricity to parts you need to have running true. If you don't work to thousandths of an inch, I guess close enough is good enough. Definitely not click bait but nice try.

[@Farmersamm]

We know we have an axis through the spindle that's true, regardless of any runout in any chuck. Your chuck could have .010 runout, but any part you put in that chuck will turn to the axis of the lathe............true. But where the problem comes, is when you take that part out of the chuck........you immediately lose center. The only true way to transfer parts from chuck to chuck is to use a 4 jaw. I see what you did with the collet, and it's interesting, but it's not a solution to the problem. A 4 jaw is the real solution to the problem. You can't make a collet for every part you put in a 3 jaw. It's an elegant one time solution, but it's weighty. Limited to one part. I do work to thou's. And I trust my 4 jaw to do what I need it to do. Granted, there's cumulative error, but the best you can do when it comes to manual machining is to try your best to limit that error. It's a tough row to hoe. I do like your stuff. I especially liked the way you busted the 29 1/2 degree myth when it comes to single pointing threads.@@joepie221
