People like to watch chips being made. Most YT creators fill that like. You show us how to make good parts efficiently and on size, knowledge we can take to the clock and to the bank... Thanks for showing us what we REALLY need to know...

33 years a machinist and watched like a kid in kindergarten learning 1+1=2 !

Total novice here to the world of machining but learning so much from your videos. Please never stop producing them, thank you, thank you, thank you.

I saw this one coming as floating datums are always bad news. A great video on overlooked problems though!

I am not a machinist, and I've never even touched a lathe, but I follow everything you're saying. Well done!

This should be the first video any aspiring machinist should see. Great stuff

Good explanation of common setup problems. One minor point for extreme edge-finder accuracy; when the .200 diameter contacts the part edge and jumps sideways, you're actually .099 from the part center line instead of .100 as commonly practiced. Usually doesn't matter but sometimes it does. Thanks again for your great teaching skills.

Thanks Joe, I'm a 40 year machinist and have been trying to teach a young guy that controlling dims, making good setups and being consistent is half of the battle. Tuesday morning I'm going to set him down and show him this video, I'm sure it will help him become better and maybe start him thinking first to make good parts rather than trying to figure out a fix later.

Thanks Joe for taking the time and energy to share these incredibly valuable tips with the community. Your experience and knowledge is priceless. Glad you got some well deserved r&r after kicking it hard for your customers. Joel.....

Cheers Joe Yet another great video Been an engineer for just over 50yrs and now finally retired Never too old to learn and I have to say I always learn something from you Keep up the good work and I am looking forward to the next one Pete from the UK

What a great video! Thank you so much! Very few KZfaq machinists post videos that are as genuinely insightful. Thanks for making it!

Flipping that rod perpendicular to the vise is a great point. thanks and welcome back sir!

Great video! I feel like I've learned so much from your videos that it would be years of working on my own to catch up! Thank you so much!!!

For me, one who hasn't had the advantage of formal training, your videos are invaluable! You have really thought things through, are excellent at explaining not only the results, but also the mechanisms behind why things happen, and you present them in a complete way so I have no doubt as to what you meant. Your review and summation at the end of many of your videos, solidifies the material you have presented and answers questions I had not dealt with during the video because I was involved in learning at the time. You are a very good teacher. And, you have helped me improve my machining . . . a lot! Thank you.

Joe your videos are awesome. My little guy Jacob is a couple months old and we watch your videos together; its our father-son bonding time. I think he's taking it all in. (Start them young) Thanks so much!

"Hey, boss, Shop gremlin" xDDD I LOVE how you do the job WITH the errors completely unmentioned. For a second I didn't even realize what the problem is. More educational materials need to be like that.

Thanks Joe you're a great teacher. Ive been making swarf 20 years and still pickup the odd tip from your videos.

I wish I had you when I was an apprentice!! I’ve been in the trade for 38 years and have had Some crabby, crusty guys that were more like a dictator than a mentor. You are definitely the latter. I vowed to myself to share my knowledge with the younger guys because they are the future of this trade.

My beginner's shop is filled with these types of gremlins which are almost always the result of assuming something or getting in a hurry. I immediately spotted the gremlin of taking two passes instead of three -- I recently got burned by trying to speed up the process with deeper cuts on thinner parts. Seeing how this taper variable affected the collet retract distance is obvious ... once you point it out. I really got a lot out of this video. Thanks, Joe!

Thanks so much for these videos- I’ve been binge watching, they’re really good. You have the gift of being able to explain the how and the why things are done a certain way....you’re a natural educator. Your sincerity and good nature shines through, thank YOU for sharing. You don’t make viewers feel stupid while you show us good ways of solving common problems. Much appreciated. Two big thumbs for up Mr. Joe Pie!

thanks Joe- awesome explanation! as a hobby machinish I've experienced many of these gremlins. this video is immensely helpful

Joe, that was another great subject, logically arranged. Now I know why I sometimes couldn't make equal parts. How glad I am that you have the gift to explain it so neatly, now all your videos are educational. Thanks for your effort

Having made the same mistake before, I knew the potential problem as soon as you gave + or - .005" on the OD and then proceeded to use a 5C collet with a stop. A really good machinist would have recognized the potential issue before running the parts but I had to learn the hard way! Hopefully you have saved some folks from making this error BEFORE they kill the parts! I really am enjoying your videos, Joe. Old, retired, tool & die maker, TreeTop

Joe you have a gift for relaying information clearly and in an engaging way... every video you spew out great nuggets of practical useful info ...cant thank you enough....love from 🇬🇧

You make the world a better place. Thanks Joe.

seriously thank you, im just a home hobbyist but i always try to run my best parts. i would have been the new guy going to the boss to ask why all my parts are different. not anymore in this case. thanks joe. you definitely have a new fan

Funny how the very first operation perpetuated the rest of the job to fail. I typically try to save the easy stuff or something I'm most comfortable with for last, although that usually doesn't work out... Great reminders here and a great video. Good to see you back on the KZfaq.

Another great video. I pick up so many great tips that I wasn’t even thinking I’d learn when I start each production. Thanks

Hi Joe. These videos are a real treasure. This one was especially good food for thought. I realize you take time out of your shop production to do these (when you could be making money on the job), so thanks again. I’m learning a ton!

Joe thx for showing how sneaky one setup is vs another setup. The analysis at the end covered all the gremlins quite well. I'll always remember the length dependence of a diameter in a collet. The takeaway here is think about what problems are inherit in a setup. If you can't change the setup then you have to compensate for each part. Thx again Joe for the insightful and practical tips and your time in producing the video.

Wow. This is brilliant. Excellent method of demonstrating lots of problems, their sources, and their solutions. Wow.

Thanks, Joe! I'm a woodworker with similar problem scenarios, and I can apply these lessons in my work, too!

MOST excellent! I'd love more videos like this. Showing how to do something is great, but showing why something failed and how to avoid it is awesome!

Another simple to understand yet exceptional video Joe, thank you.

Thank you Joe for taking the time to make these videos...... You taught me to perform a more careful setup!!

I’ve learned a lot over the years from others and some by mistake. But this type of video is a pleasure to watch. Thank you very much

This channel is just such a fabulous resource ! Thank you Joe, for all the work you put into these videos !

I really enjoy learning from your videos. I recently bought an old Harrison M400 lathe and a Summit mill for my hydraulic shop. Most of my jobs are building new chrome rods that people bend using their 30hp Tractor as a D5. Turn the end down and cut some threads. I did get to chase a 5.75" nut with a buttress thread the other day. I had to make the tool holder and grind a piece of HS steel to get the job done. Certainly appreciate your time producing these videos.

Brilliant video. I love the way you put this together, showing each setup without mentioning the problems first, then coming back to analyse everything later. Thanks very much for making this!

Very helpful instruction. One tip about edge finders for very accurate use. Even high quality tools with lapped surfaces sometimes stick and refuse to jump over consistently. To help this problem separate the mating parts slightly and add a drop of light oil. Also, once the end jumps over, even slightly, you've already moved over half the diameter for the tool. For .200 dia. tools move your table .1995 for improved accuracy.

that was great, well explained, very educational, thank you, we need more insight and technics like this video, keep up the great work!

Hey Joe, Really enjoy watching your videos. I am an apprentice engineer/machinist and your videos have really helped me out. I have even taught my boss a few things that I've learnt from you, especially your video about setting precise angles. Keep up the great work.

Thank you Joe for demonstrating the variables in machining 101. This is a valuable lesson that I have tried to explain to others in the past. Now I can just send them this great video you made that’s perfectly illustrated with explanations of why. Straight, Flat, Perpendicular, Cylindrical And Parallel down the line equals good parts. 👍

Hi Joe. Always enjoy your videos and learned a lot from you. Being semi retired from an engineering career - earlier as a toolmaker/production machinist at an advanced level - and later as a manufacturing and mechanical design engineer...enjoyed how you explained everything (and tested the viewers). You are a terrific teacher and the viewers are lucky to have you.

Another great video, I did get three of the gremlins, because I had them happen and had to ask my journeyman how to fix them. As always Thanks for the information and for the time you spend getting everything set up and putting them out.

One of the best machine tool teaching videos ever !!! thanks yet again.

As a young machinist that's only been in the trade 10 years I'm enthusiastic about it and always looking to learn something (even in my off time). I sincerely appreciate an old head that's willing to share his experience and knowledge. I try to absorb as much as I can about the why and how and a lot of experienced guys don't want to share with the younger generation. Keep it up, there are those of us young guys that want to be proud of what we do. Thanks again!

Just found your channel and as a retired machinist/toolmaker you have already taught me something I didn't know after 40 years of cranking handles. Fixing to set up a mini-shop at home and I'll be sure to tune in and search your knowledge base regularly. (That is one thing I really miss about machine shop; a good machinist always willing to help make a better machinist.) THANKS!!!

A lot of great advice on that one some I would have never thought of, the idea of using another part or same diameter in the other side of the vice I've done for thirty years, didn't learn that it just seemed like a good idea at the time. Another great video Joe, you are truly a great instructor and insperation.

I got the eerie feeling that the hair on the back of my neck was standing up from like you were standing behind me and watching every mistake I made and then compiling it into this video. Your explanation of things going wrong during machining hit the nail on the head! Thanks for sharing and keep up your great work!

Joe, I'm an engineering student but took 2 years of manual and CNC classes at the community college before I started engineering school. Your videos remind me of lectures back then. I miss being in the shop! Thank you for the tips

Great vid. Never thought about diameter affecting finished length with a collet. Makes perfect sense when pointed out.

Thank you!! most of your info. goes over my level of skill , however I still learn so much each video I watch !!

Thank you for this. As a relative neophyte to machine work I have just learned something that took other people years to figure out in the time it took to watch this video.

I learned this trick while working 3rd shift in a production shop , if you're following a 2nd shift operator who hasn't kept track of his O.D. tolerances , measure ALL O.D.'s & group parts according to size . Start with biggest O.D. , set O.A.L. & face to length . Then change length for next sized group , with a 5C collet ; .001 Thou. on O.D. = 0.006 Thou. in length.

An excellent instructional video. I learned a lot. Thank you Joe!

Awesome vid Joe! Like you said, once you're shown what went wrong, it makes perfect sense. I did think of a vee block before you mentioned it. Machining a vee block was one of my first assignments in 10th grade machine shop back in 1980. That's when I fell in love with a beauty named Bridgeport.Thanks for posting! :-)

Thanks. 35 yrs machine builder, retired. Brought back great memories of trying fig things out in the early days.

Fantastic example of compounding errors. Thank you Joe!

I'm a home shop guy (although I do some prototyping side jobs) and I immediately caught the problem with the diameter, but never realized the severity of all the follow-on problems caused by the diameter. Outstanding information, Joe. Thank you!

That was superb. Work holding can be easily overlooked, especially by the novice machinist. Thank you.

As always, very valuable advice! Thanks for sharing and keep up your great work!

Hi Joe, I was enjoying you were constantly moving the reference point to get further away from the goal... ;) It's one of the first things we learn in school, keep your reference at one point and keep it there... Very good video on the subject and very well structured... Cheers, Pierre

Great video Joe! Really makes me examine every step of a job. I am a hobbyist and this video was extremely helpful.

Great video Joe, Please don't stop making them.

Hey. Just wanted to say thank you for the free education. Even if you had no clue what you're talking about (obviously you DO know what your talking about). You're taking your time to try and educate others with out considering personal gain or what you get out of it. It says alot about you. Keep it going sir.

Another excellent topic . Very often overlooked Well done Joe

Great lessons there 👍 Blowing off chips into the collet, could introduce an obstruction between the stop and the registering end of the next piece, as the chip can fall into the space, when the first part is removed.

Lots of useful things to consider Joe - good video.

Happy to say I watched this for the second time, a few months later, and spotted all the problems. You're doing a real service and I hope your wolf spider makes you a billionaire lol

Joe you keep on talking and I keep on learning. THANKS!!!!

Fantastic videos Joe, keep up the great work!

Gee i am a hobby machinist and i know have a new found respect for tool shop machinist. Another great video Joe and i am loving the content.

MM ? Not a friend.......nice to see you back.

Joe; You are fantastic !! Thanks for sharing Mark

Great vid as always Joe!Thanks for posting,and have a nice,safe Memorial Day!

I've watched dozens of your videos but I think I got more from this one than any other. Modeling your jig/setup after the measurement in the spec is really simple and effective. Most of my gremlins occur in surface finish. I have a lot of motor vibration that makes such a mess of my surface finish that I never bother with tool chatter! Every job ends with a lot of sandpaper and Scotchbright pads. LOL

Outstanding video! Thanks for taking the time to educate us. Great info! Fred

Good stuff, Joe. I've experienced some of those myself and couldn't quite see the mistakes. Attention to detail. Thanks, John

I just drill some parts as you showed it in scenario No 1, but it makes sense that scenario No 2 is more accurate using a v block for better results like perpendicularity of the hole drilled to the OD. Thank you very much for sharing your experience. I'll do that next time.

Lots of food for thought there Joe. Thank you.

Glad to see ya back, Good info as always,

Really good info! I never thought of how much could go wrong. Many thanks.

Spot on, on all points, Joe. I can also attest to having seen many people make most of these mistakes and then scratch their heads about it. I like the solutions you give, especially the soft V-Block, I have often used ad-hoc aluminum parallels so I can drill into them without worry, but I hadn't thought of a soft V-block for crossholes.

An eye opener to say the least, time very well spent. Thanks!

Great video, really appreciate your work and delivery. Keep em coming.

As just a hobbyist I still find this super helpful. Keep up the videos.

As always a great video Joe. Thank you. I learned a bunch.

as always great video joe. thanks for sharing your knowledge.

Another great lesson Joe. Thanks!

Brilliant and simple as usual thanks Joe !

Brilliant Joe - Love your videos Thanks for sharing

WoW! That was great. I never paid much attention before, but this is right on the money!

Passion and Knowledge is an Amazing cocktail and you sir have Both in this subject great as always.

Great advise Joe. Being new to machining it's nice to get some pointers before I screw the pooch on parts. Learning the hard way costs too much in tools and materials. Thanks.

as always, learned a lot. thanks for taking the time Joe.

Great stuff Joe, love the V-block tip!

I'm new to machining . you have explained these points and it all makes perfect sense.

I've learnt something useful tonight watching this video - Thanks for explains these issues so well

Really great information. Being retired and a hobby machinist I have yet to make more than one or two parts: BUT thanks to your information I will be able to improve making one or two parts! Thanks, thanks, thanks!
