Our shop closes down between Christmas and New Years. I came across this video while I was off. Yesterday was our first day back. The first job they gave me was 4 saw cut pieces just like you had in the video. Work's little slow lately, and the parts weren't due out for a few days, so I decided to try this setup. There's a bit of time in the initial investment, but now that everything is set up I can use this again and again whenever I need to
Joe, "elegantly simple" must be one of your mantras. This is great. It's quick, easy, to implement, hard to screw up. I know this vid is way back in your rear view mirror, but it's still educating people. Thank you.
I'm 75, not a machinist. I've had a 12x48 Atlas/ Craftsman, now an old SB 10". Jet mill drill. I don't use them much, and probably not very good. Even so the videos I've seen of yours are VERY helpful to get my old mind jacked up, and make one think.

Great idea. I can say that because I've used that for 35 years. I had a great teacher when I was stationed on Korea. He had been a machinist for 60 years. Didn't speak a word of English but we understood each other perfectly. Guy could drink me under the table too.
Not a machinist, just an IT guy who likes to learn from smart people. Started watching AvE, then Abom79 and after poking on other videos that the algos suggested, I finally landed here. Your efficiency of delivery, techniques, and talent are top-notch. When I go back to tech, I'll be working in data centers, so I welcome these lessons mechanical and verbal competency.
Thank you very much for the compliment.
Joe and This Old Tony do some pretty neat stuff.
Just came across this video, I've been a US Navy trained machinist for over 50 years and this is one of the coolest tricks I've ever seen. I'm going out to my shop right now and do this mod to ALL of my lathe chucks. This trick is genius. Thanks Joe
Good to hear. You're going to like this.
Joe you never cease to amaze me So simple yet so effective After 52 years in the trade it's little things like this make me want to kick myself It's always great to watch a master of his trade Keep up the good work Joe as I will be looking forward to the next video Pete from the UK
Thanks Pete.
Whenever I need to machine a thin part, I get a parallel, sit it on the bottom two jaws, resting against the face of the chuck and push my part up against that. Just some advice for people that aren't in a position to modify their chuck.
Great video, really clever.
Wel Joe,i am a beginner and learnt more from you than from a school that i have to pay for.
Thanks a lot for teaching us so that we can work safer and faster.
Greatings from Hans in Holland
Greetings Hans. I happy to help.
I started watching and i said to myself, "I'm not gonna drill my chuck." I watched the whole thing and I said to myself, "I could set up a jig to do that drilling pretty quickly." Subscribed...
Thanks. Once the threaded holes are in the chuck face, the setup is very quick when needed.
Joe, I just wanted to thank you, along with other RUclips machinists, with inspiring me to make a late-in-life career change. I've enrolled in my local comm. college and have recently started making chips of my own. I find that I am enjoying making small bits of metal out of larger bits of metal. :)
Even though I am strictly a manual machinist, I did enjoy watching the CNC series. The chuck modification is a great idea. and beats fumbling with loose parallels when making a set-up. Thanks for sharing.
I'm not sure how I missed this! I've seen a lot of your videos Joe and as soon as I've pressed the 'comment' button I'll head into my workshop and put the chuck on the mill. I'm a huge fan of soft jaws as my small cnc machine doesn't have a tailstock (yet) but this will add another dimension to my conventional turning. Thanks once again from the UK.
I see a couple of people have made comments about the fact that their lathes/chucks/jaws must be so much better, more accurate etc etc. That’s all well and good, but for those of us who don’t own a super expensive lathe and/or mill this is a great idea. Thank you.
I like how you make most all of your special tooling instead of buying it.
Something that confounds me to no end with other people.
The other is how you dont just copy what the other ones are doing and go your own way.
A true professional.
Please continue on.
Thanks.
Thank you sir.
Job for the weekend.
1. drill and tap holes in my chuck.
Thanks Joe! The AR milling was very satisfying to watch :)
Old Dog learns new trick..... Thanks Joe, I will be doing this mod myself at first opportunity.
Yep.
I'm interested in machining and my next big purchases will be a mill and a lathe. You have yourself another subscriber.
Ron Rico welcome aboard
Joe, whenever I get to the point of being able to setup my shop I'll always come back to your videos for setup, you have the best and easiest setups I've ever seen and thank you for taking time out of your day to share your knowledge
Yet another great tip - I have lost count Joe of all the super useful stuff you have given us. This to me sure beats a spider... love it.
Thanks. Glad to do it.
Man Joe...I really think your channel is a gift to RUclips and especially to newbie machinists like me! I’ve learned a TON from your videos! Please keep em coming! 🤙 All the best man!!!
10 out of 10 Joe. Once again your lateral thinking shines through! I've mucked around with spacers, and held the workpiece thereon with the tailstock and centre, but I never twigged on to your idea. Sometimes the bleeding obvious is to difficult to see.
Well done.
Pete
Great video. As a newbie to the lathe I found your way of achieving the same thing a spider does so much more useful. I have been searching for weeks on how to build a spider without a milling machine. Not only that it will be easy to make different lengths with your method , and to think you were able to explain and demonstrate in a matter of minutes the most common sense way of getting around a problem. You also got a new subscriber. Thanks for taking the time to help others like me.
Thanks. Make sure to hit that subscribe button to seal the deal.
Joe, I watched this again today and appreciates your kindness in helping the rest of us. Now I have to still and tap my chuck. Thank you
Nice set up. I have used .125" thick parallel bars off the chuck face. Rotate the 3-jaw chuck so one jaw is pointing up. This allows you to lay one parallel across the 2 lower jaws, while you hold the second parallel higher, and pinch it against the chuck face with your work piece as you tighten the jaws. Just don't forget to slide out the parallels before you turn on the spindle. :)
Great solution for this problem. Thank you Joe.
Always a pleasure to see and learn from a true pro, with true knowledge.
Not really into the AR-15 hobby but I enjoyed the series. I appreciate the way your videos move at a good pace. The right amount of information well delivered. Your work methods have helped me learn some very efficient ways to save a lot of time.
Excellent. Glad to help.
Excellent! Learning to not be afraid to modify/improve tooling such as chucks.
This is a great way of assuring parallelism, and cheap to do! Thank You! JD
Its rock solid.
You sir, make me smack my forehead everytime you produce a video! "why didnt I think of that?! Ive been doing it the hard way all this time!!" Thank you, for each and every one of your videos!
Simplicity is beauty
Great tips. I have told several of my coworkers about you and your RUclips channel. Thanks for sharing your knowledge with us.
Incredible... As always... The best ideas, are looking very simple.. thank you for sharing...
Another awesome way to do it better, thanks again Joe.
Joe, I've been a Tool & Die Maker for 45 years and that by far the best lathe tip ever. I'm heading out to the shop now to drill and tap my 3 jaw chuck. Thank you very much Sir!
I appreciate the comment. I just got tired of fighting jaw movement on older chucks, bored or not. This is bullet proof. Enjoy.
I am new to this and spend a bit of time reviewing RUclips clips. This is fantastic I like the no fuss attitude the factual commentary well backed up by expert experience. Keep uptake good work. Your threading tip is also inspiring.
Great idea! I can't believe that many people gave it a thumbs down.
Excellent little tip here. Thanks for sharing.
Awesome idea Joe , I've been a toolmaker/ machinist for 40 yrs and the one thing about this field there's always something new to learn I just started watching your videos always something interesting keep up the good work Thanks
Nice. This works very well and doesn't scratch the part.
Thanks for getting back to your patented instructional videos. The AR series was entertaining. However, you are the best - if not only, video maker that finds a common machining problem and offers a logical step by step solution. Other videos are of the "here, watch me do this" verity. Keep up the tremendous work.
I think you are a very smart man,
Also you are answering people in your comment section. Thank you. Atlas 10F 54 just learning at 60.
I try to keep up with all the comments, but they come in pretty fast over this channel. Thanks for the comment.
Thank you Sir, I've learnt something new today. I find your videos fantastic
The biggest issue I have with Joe Pies videos are that I always seem to watch them a few days after I needed to watch them. 😏
In my case it would have worked out well to bore a hole that was bigger than my spindle on a piece of 1/4 plate. parallelism wasn't even critical, but not having to mess with parallels or scrap plywood to get a nice clean and tight offset (4 jaw) would have been so easy and convenient.
my man always seems to sneak in some safety easter eggs into his videos too. (marking the jaw safe-limit, not running lathe with nothing in the jaws.) This is incredibly valuable to a hobbyist who doesn't have a crotchety old machinist near by to share some tips and horror stories. My dad is missing two fingers (table saw accident), so I'm well aware that bad things can happen - really appreciate the tips.
THANKS AGIAN JOE.
I have 2 uncles missing digits from industrial accidents. I'm more than happy to share things that may keep that from happening to my viewers.
Dear Sir ......wow from down under in Sydney Australia , this is the most Brilliant approach to maintain Parallelism , most of all Thank You for sharing your Idea ...
brilliant idea - so simple.
The best and Most useful videos I have ever found on RUclips
Thank you for the compliment.
as with all your other videos, a great amount of insite and very helpful
This was so simple I cant understand why nobody has shown it before. Brilliant!!
I love this trick!!! Thanks Joe!
That is badass!!!!
I wish you were my tech instructor, or did an apprenticeship under you.
Thank you for sharing.
I appreciate that.
I like your ideas as to how simple it is yet you get accuracy from using it. Experience comes into play.
Thanks very much.
EXCELLENT! This is a huge safety improvement too! I recently launched 123 blocks and a parallel on 3 different occasions because I forgot to remove them from behind the workpiece during a lot of repetitive setups. This would have sped things up a lot and made them much safer!
You make everything look so easy.
Thank you. Its taken a while, but I think I got it figured out.
Joe great teacher!!! great stuff! thank you
Hey Jimmy. Thanks for stopping by. If you have any specific questions and Kevin L. isn't around, shoot me a message. I'll help you if I can. Take care.
Man that's so dam simple it's genus.
Your videos are always valuable info and you go straight to it without all the pointless rambling.
I appreciate it.
A good idea, for making the stopper/block on the jaws, i will try it. Wish U luck Brother!!!!!
That was great Joe!
This work very well.
Great idea Joe. I have followed you for a few years now and i still learn something from your lathe videos (even after being exclusively a turner for 15 years)
Thanks. I have to admit, I have more lathe experience than any other machine in my shop. I have had to be pretty creative over the years. You can't cut it, if you can't hold it.
Hello Joe! I would simply like to thank you for taking your time to teach very useful techniques, which save a lot of time, especially in serial works.
Simply, thank you, thank you very much! Greetings from this corner.
Glad to help. I hope these videos make a difference.
thank's Joe
very good for thinner parts and not only for parallelism, but repeatability across multiple parts or when you want to take the part out, you can replace it exactly in the chuck. thanks so much for sharing! subbing!
Very good tip. Always fiddled with parallel pieces.
Greetings from Germany
Great Idea and demonstration Joe! - I so needed this earlier this week, I am certain the need will come up again.
Good Tip
Thank You that a great Idea.
I use it all the time.
I watched this some time ago. Came back to view it and picked up a few tips that I don't recall noting the first time I viewed the video. Thanks for the excellent video.
Glad you enjoyed it!
I am so thankful that you take the time to share such truly useful techniques with all of us. I for one have been helped a great deal by your super videos. Thankful here, very thankful and better able to do work with each passing video.
you are the great master
That's a damn slick modification!!
Both my chucks have received this modification. It really makes a difference now I am getting the kind of results that I have wanted all along. Thanks Joe!!!
Great technique Joe.
I will be modifying my chuck and doing the same.
Thanks again,EM.
You have very clean shop, mine looks like sanford and sons yard.
Thank you. I do a lot of medical devices here, so appearance is important. Plus I hate working knee deep in chips and dirt.
Elegant!
I rarely see a tip/ trick that I haven't seen or used before but this one qualifies and when I get time I think I'll be drilling some holes in my lathe chuck to use this trick myself. thanks for the tip
You're welcome
Fabulously instructive and straight to the point. I just got my first lathe at 68 a week ago and I'm still a bit wary of it but I can't wait to get stuck in with some of your advice and ideas. Have a great Festive Season.
Great idea but for a one off part I take and face off a disc of aluminum in the chuck and then superglue my part face to it doesn't matter if it's round or square or not centered whatever then just heat up the part to release the Superglue works fantastic you can turn to a very thin thickness to
Neat trick
Great tip! Always learn something watching your videos. Thanks for taking the time to produce them.
Once again Joe knocks it out of the park... Thanks
Every video you make is excellent. I don't know how you get thumbs down. I'm about to clean up my fathers lathe and vertical mill they are covered in dust and grime. What do you reccomend for cleaning them?
Get the dust off first. A shop vac works well for that. ZEP makes a great line of purple degreasers, and most home centers also have purple power products.
Excellent video,love the way you explain things with no nonsense direct and to the point! Ok time for a noob question since I am one. Do you think it would be wise when you make standoffs like you did to mark them so they always end up in the same spot on the chuck to keep the perfect accuracy? Again thanks for the great video's and yes I still hate spiders lol
Doesn't matter, true them with the tool every time if you have to.
Wow! That's what I call slick. The simplest solutions often elude me. Thanks for your great videos.
One of the best tips I've seen in a long time
Could just use parallels to square up the part tighten remove parallels.
You can. Many people do.
I thought about the parallels, but like the idea of something solid behind the plate. Great video. Haven't done a lot of machining since high school, 47 years ago, but am thinking about setting up a home shop, now that I have time on my hands. Us old dogs do like new tricks. I got a lot of lathe time in high school because I was willing to learn to use a huge 4 jawed turret lathe that no one else would touch. Learned to love that lathe.
You could, but then it'd be a bit of a balancing act even if you got into the rhythm of it. For one-offs parallels is better, for large quantities, standoffs is more convenient imo.
yep
I have used parallels
Excellent demonstration. But what you will do if the same part has small diameter?
A single parallel slipped between two of the jaws (lay the flat across the jaws) that you back the part up against is a quick-n-dirty solution. In fact, I just used it to make a set of standoffs to mount a control transformer on its side and they all came in at 20.165mm +/- 0.005 (ie - about 2 tenths imperial). File under: it's better to be lucky than good.
You sir are a wealth of knowledge,easy to follow and spot on. I really enjoy your videos. Thank you very much.
rick b
That is awesome as all hell. When I eventually get a mill, I'm going thru all of these videos and am going to make all the simple tools to make machining easier and more accurate for my lathe an mill when I finally pester my wife into letting me get one. Thank you Joe. Love the content sir.
Curious why you didn’t flip the jaws around
Other people asked the same matter in other comments, and the reply is that reversing the jaws, if the piece to be worked "seats" in the internal jaws steps AND it's not so thick, you have to work with the highter steps of the jaws running outside. Moreover i say that fixing the piece only with the jaws is not so much accurate than setting the piece on the studs and THAN fix it with the jaws . . .
I likey
Works like a charm.
A very simple thing to do, yet it has fantastic result. Thank you!
John
Excellent trick......will have to add this to my repertoire. Thanks for taking the time to demo this.
Looks like you've done this before?
what a waste of time. on all new chucks the face of your chuck runs true - if not face it. it is repetable if you take your chuck off the machine.
then go to the mill and stick two paralells between your part and the chuck.
thighten chuck. use hammer to tap it until both paralls are tight.
take paralells out.
face 2nd side. you will get better than 0,02mm. no drilling, no standoffs.
Greets from Germany.
But you do have to tell the boss you need a mill so you can face both sides of a part. thats going to end well. Good luck.
@@joepie221 No just take the Paralells from the mill and then go back to the lathe.
@@Hardcor3crash When I developed this solution, I was doing exclusively semiconductor work. Building the plates that handle wafers during their coating and processing. Surface flatness, part parallelism and surface finish were absolutely critical to an acceptable part. Though your technique of using mill parallels will work if snug, the fact that you can remove them would indicate the part wouldn't be parallel to this degree. If you had to tap the parallels out, the track left behind on the part, would have scrapped all the parts I was working on. I even had to be careful of tapping my parts against any standoff for fear of leaving a cloud on the part where it registered. Parallels are OK in a pinch, but this is better.
you are so correct man, thats what paralles are for
more greetings from Germany
@@lokkas3637 I need to know who you are in agreement with before I reply.
So many videos, so much knowledge. Not enough time to consume them all. Thank you for doing these videos...
You have so many quick set up tips, you should write a book. I have learned so much from your videos. Keep up the good work.
Just another reason why I love your videos. Please keep up the good work.
I learn at one thing amongst everything else from each of your videos, this time the adjustable heels on the clamps, thank you for sharing your knowledge.
Very technological technique, concisely and efficiently. Thank you!
I really like your style! Your thinking out of the box and simplifying tasks is great! And then passing on that info to us! (82 year old and still kicking)
