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...
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.
I am an engineer with over 30 behind me and am now retired. Other then design I have also have made my share of chips and have been responsible for others, but .I too watched just like you did This guy is a TRUE machinist. Hate to admit I have been nit in the ass by the collect registration before. More then once TOO!.
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
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.....
A great insight to the thought process of a skilled machinist setting up for any job, large or small. Brilliant content Joe thank you for the hours you put in on this type of topic. I'm retired and six years into my hobby journey and you have saved me hours of heartache, and saved me a heap of material from the scrap bin! 😊
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.
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!
"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.
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
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.
Unfortunately, knowledge is about the only thing 'you can take with you' when you go. Why not spread it around and help someone before that time comes. I've worked with those insecure, paranoid, crusty old guys and never enjoyed it. They are usually worried you'll steal their jobs.
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.
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 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 🇬🇧
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!
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!
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
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 RU-vid.
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.
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.
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
Honestly, that is the only part of the video that puzzles me: It's obvious the influence of the difference in diameter when using a stop on a turret/tailstock (e.g. turret lathes, screw machines, etc.). But, either you're displacing the stop (therefore, you're getting parts longer and longer during the production run), something possible with that type of stops, held in place only by a set screw, or the stops holds up properly and the collet jaws slide slightly on the part, when it bottoms to the stop.
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.
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.
That taper though; I was taught that a 3:1 length/diameter ratio is a magic number for many things, one of them being as a general guideline for how long is long enough that I really ought think about supporting the other end of a long part.
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!
Yep... one of the better channels on youtube. fwiw) The best way to support channels like this is to hit the like button, subscribe and also hit the bell and select "all" ~2c
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.
Anyone that has loaded parts in a collet or any other machine with a stop can tell the click vs the mushy thud of chip interference. For safety, if you are scared, blow it off before opening the collet.
Hi Joe, another fantastic video! Very useful for so many viewers who are doing similar jobs, and run into the problems you showed! Please shoot also a video with tips for better results of finishing O.D and facing of (cheap cold rolled steel) Cold rolled steel is daily used by many people to produce parts, but finishing results are many time not really up to the expected satisfactions.
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
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!
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!!!
Again, another great video! Fixtureing is much more difficult than it first appears. I bough a book on the subject and there is a boat load to learn. Your examples were excellent and not exaggerated to make your point. Are you going to the BarZ bash in Southern California in June. I would love to shake your hand in appreciation.
Hi Joe, I recently had a very similar problem when trying to drill a centre hole through a piece of 6mm stainless steel stock. There was too much deflection (as the hole position was near the end of the part and the drill press chuck and vee block clamp seemed sure to collide) when I started applying downwards pressure on my drill press. As luck had it, I was only drilling a 1.5mm hole the the relief inside the 'V' block I was using was greater so I was able to push the hole right through. Your demo had made me re-think my approach to set-ups when evaluating the best way to get a job done. Anyway, It still scares them crap out of me using drills that small. (I purchased a pack of 10 cobalt drills for the job and only destroyed 1). Thanks for the insight. Kindest regards from Bonnie Scotland. Joe M.
Good Morning ( Texas Time ) My presence at the Bash is still up in the air at the moment. I have been invited. Thanks for commenting and taking the time to watch these. Much appreciated. Congrats on the box.
this is brilliant. we all get in trouble in the early days with this. some guys carry on thrue there working life like this. this film will help a lot of guys make there life easy. cheers joe.
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!
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.
Hi Joe my name is Damian I'm 28 years old from California and I wanna thank you for your videos super helpful and full of knowledge, I work in a company as a fabricator, the 95% of the stuff the I make is for Disneyland so I really take pride in my work, I wish I can share all that stuff with you guys but I can't Disney Rights, I'm AWS certified welder in all three different process GMAW, GTAW, SMAW in different materials, thickness and positions I do a lot of sheet metal working, I'm proficient in AutoCAD, solid works, Maya and a couple of more software's and cnc router but I also do alot of machinist work in conventional mill and lathe but I know that I still don't know A LOT of stuff because I'm not a full time machinist, actually I'm still a rookie but I have a pretty good common sense and detail oriented so I can figure some things out even when I don't know how to do it, and also I'm not afraid to ask, so when i start watching your videos a couple of days ago man I got suck in watching them all so thank you for all the knowledge that you put out there, and one last question, I would like to purchase my own lathe I'm really falling in love with this machining work I got my own Bridgeport milling machine few weeks ago and I'm planning getting a lathe, any recommendations???
The problem with putting parts in vises that are short, and one one side, is something that is a very bad problem, and something I rag upon all the time. It’s surprising how many machining people (admittedly, mostly amateurs) don’t get this. But sometimes, even well known pros do this. Since the solution is so obvious and easy, I just don’t understand why the don’t get it. I always make a small piece the same width as the part when I know I’ll have this problem. I have a small box of all different sizes of these pieces, with the sizes written on them. Also, yes, I have a full 72 collet set in 5-C, in inch, plus another couple dozen others. But you’re right, it’s hard to predict the length of a part. The other problem is that the diameter of the part needs to be very close to the nominal diameter of the collet, and not oversized. I also have ER collets that don’t have these problems, though the stop is in the collet chuck, and doesn’t allow for long parts. The other problem is that because of the collet design, it’s required tremendous force to properly close them-up to 130 foot pounds for the largest size in ER-40, and 150 for ER-50…whew! Even with my large torque wrench I can’t manage that. A high quality centering vise works as well for those poor spec parts. That’s all you got is more than what most people got.
When I have to hang a part out of the end of a vise jaw, I keep one of the actual parts on the other end to stabilize the jaw. I simply swap that part out for one thats done and finish that one last.
Hey Joe, thanks for putting so much time into these videos, I've learned a ton of cool tricks! When you say your edge finder has a center finder on the other end, I'm assuming it's one of those conical ground points. Can you show how to use that and a couple practical applications? I've always wondered. Thanks!
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. 👍
Very good video Joe, it reminded me to stay true to the fundamental principles of mechanical accuracy. Although I'm not a machinist but a college student in industrial design I feel the knowledge I gain from youtube machinists is very valuable. Thank you for making these videos!
I'm not entirely sure yet, after all I'm only in my first year. But I'm pretty good in CAD, technical drawings and just making stuff. I can do the aesthetic part too but that's not something I would want to spend my whole day on. We have a lathe and vertical mill at school with which I can freely play around and try things. I got pretty deep into it and I started buying my own offshore carbide cutters (they provide cutters at school but those are kinda crummy). Up until now I've just been doing small stuff, experimenting and cleaning the machines up since they really aren't cared for there. I have a little collection of scrap and new steel and I'm hoping to do some projects soon.
I thought 33 minutes was too long. Now is too short. Packed full of practical info on how to think like a machinist. It is quite good for me because I am just beginning to dabble in this field.
I have two video requests. First is care and maintenance of cutting tools. My aluminum-cutting tools get "sticky". Second is setting and using two vises on a mill. A couple times a month I wish I could clamp more of the stock metal. Thank you.
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 I enjoyed watching the video. You describe what you are doing so that the untrained can benefit from you knowledge. I noticed that when you turned your part around in the lathe that the difference in diameter would not allow you to insert it. I only use hardinge collets which cost more but they have more spring which allows a slighter large diameter to be chucked plus it is less likely to scratch the part plus they are more accurate then the foreign one. If I was doing this part I would have used a collet block (brown block) rather then using the vise but large differences in diameters would restrict it's use. Big fan. Charles Boston
Now that's brilliant beyond words! What about putting a clamp downward on the part to compensate for the movable jaw riding upward and causing the hole to be off-axis?
Awesome info man!!! Especially for home gamer new machinists like myself, it would have to taken me a long time to figure that stuff out on my own. Great videos...please keep it up!
When you do an apprenticeship you spend your time learning to think like a Tradesman. Experience teaches you how to become a Journeyman. I have learned a lot, Thank You!!!!
