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...
As a hobby machinist, i cant thank you enough for doing videos like these. I appreciate seeing you answer questions on an old video too, your a great teacher Joe.
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.....
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.
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 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!
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.
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.
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!.
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
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 🇬🇧
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.
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!
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! 😊
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!
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.
I’ve paid an awful lot of attention to these videos. I find them very interesting because of the different processes are so well described and demonstrated. A lot of the information I already know, but the v block handling varying diameter caught me off guard. Very simple and very clever. I appreciate the information you share, looking forward to checking out more of your videos!
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!
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!
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
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
"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.
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 UA-cam.
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
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.
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.
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.
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.
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.
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'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
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.
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.
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.
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!!!
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
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
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.
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.
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???
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.
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!
Taper wasn't really mentioned much....but the taper from turning the pins can burn you too. You want the pins to he straight as possible. Using a v-block helps, but doesn't eliminate the error. One of the things I had a helluva time getting through to my apprentices was the fact that on some things, just because you have a tolerance does NOT mean you can use it, because using that tolerance will burn you later.
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. 👍
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.
You know what really impresses me is that because of your shirt I just learned that you are a business owner and you still take the time to reveal tips and tricks (unlike the other 2) that give your "trade secrets" away to benefit others in the trade. You however don't have to worry about my competition as I'm in Canada. I really enjoy your videos, especially on reverse feed threading. Thanks Joe!
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!
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
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.
Nice video! I'm new to milling metal, but with wood I've done a bit of setup. The rule works to register from the critical point. The v block concept is new as a fixture. Thanks!
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!
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...
Its cool to watch big machine chunking away, but I like to provide some theory and knowledge you can grow from. Thank for the comment.
As a hobby machinist, i cant thank you enough for doing videos like these. I appreciate seeing you answer questions on an old video too, your a great teacher Joe.
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.
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
I am not a machinist, and I've never even touched a lathe, but I follow everything you're saying. Well done!
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.....
Thanks. I needed it.
This should be the first video any aspiring machinist should see. Great stuff
Thanks. I agree.
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.

Thank you Joe for taking the time to make these videos...... You taught me to perform a more careful setup!!
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!!!
Excellent. Thats the plan.
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!
Start tight, finish right.
I'm a home gamer too and knew right away that changing from three cuts to two it would go down hill from there.
You make the world a better place. Thanks Joe.
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
Thanks for watching.

Excellent. Thanks.
Excellent tip. I can still remember my first part where I encountered this and NEVER FORGOT this lesson.
This should be a training video for apprentice programs.
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
I am glad you cringed. I was looking for that effect. Thanks for watching.
"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.
@@kristiandecker7230 go away you autistic parasite. You and your stupid spambot.
Fantastic example of compounding errors. Thank you Joe!
Glad you enjoyed it!
I saw this one coming as floating datums are always bad news. A great video on overlooked problems though!
Gotta be careful. Even on simple parts.
One of the best machine tool teaching videos ever !!! thanks yet again.
Thanks. Its real world stuff.
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 UA-cam.
Right...This job was doomed before it got to OP 2. Thanks. Good to be back.
Wow. This is brilliant. Excellent method of demonstrating lots of problems, their sources, and their solutions. Wow.
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!
Some reasons are just not obvious. I'm glad this gave you something to think about.

Great vid. Never thought about diameter affecting finished length with a collet. Makes perfect sense when pointed out.
alleznape it's very dramatic if you even adjust the draw bar

Thanks for the compliment.
I'm just getting into 5C usage and this was really eye opening. Thanks Joe. You are teaching me so much in all areas of machining.
Glad to help.
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.

Agreed. A box tool would be better for this if available.
Any taper should be removed before you proceed.
Thanks. 35 yrs machine builder, retired. Brought back great memories of trying fig things out in the early days.
All you need to do is look. The answer is already there. Buried, but already there.
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
Try to insulate your machine at the feet. Motor noise is amplified from the ground contact. My lathe sits on thick rubber dampers.
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.
An excellent instructional video. I learned a lot. Thank you Joe!
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
I love you joe. Such an honour to live in a time where we get such amazing knowledge for free.
Thanks, I'm happy to pass it along. I hope you'll do the same.
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.
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.
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!!!
Glad to help.
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
Lots of useful things to consider Joe - good video.
Another excellent topic . Very often overlooked
Well done Joe
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
I'm new to machining . you have explained these points and it all makes perfect sense.
They are applicable across the board. Keep the problems and solutions in your book of knowledge.
Thank you!! most of your info. goes over my level of skill , however I still learn so much each video I watch !!
As just a hobbyist I still find this super helpful. Keep up the videos.
You bet. Back soon.
Another great lesson Joe. Thanks!
Great video Joe, Please don't stop making them.
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.
Fantastic videos Joe, keep up the great work!
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.
Hi Joe. I plan to do a video on a 'Floating Chuck' You want to see small....wait for that one. Thanks for watching.
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???
If you can find and afford one.....a 15" clausing is the perfect choice. A 1620 Victor is also a good machine for the money. Thanks for watching.
I find a really nice TWS/ EL 1654 for 5000 what you think?
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.
Outstanding video! Thanks for taking the time to educate us. Great info! Fred
Thank you
Great video Joe! Really makes me examine every step of a job. I am a hobbyist and this video was extremely helpful.
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!
It shows invisible gremlins that could really ruin your day.

Very interesting subject very well explained. You're a first rate instructor Joe.
Great Video Joe. Details, Details, Details.
Taper wasn't really mentioned much....but the taper from turning the pins can burn you too. You want the pins to he straight as possible. Using a v-block helps, but doesn't eliminate the error. One of the things I had a helluva time getting through to my apprentices was the fact that on some things, just because you have a tolerance does NOT mean you can use it, because using that tolerance will burn you later.
Joe; You are fantastic !! Thanks for sharing Mark
Thanks Joe. Can't tell you how edifying these videos have been.....thx again.....Knoxville.
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. 👍
Good stuff, Joe.
I've experienced some of those myself and couldn't quite see the mistakes.
Attention to detail.
Thanks,
John
Lots of food for thought there Joe. Thank you.
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.
I hope so. This is one of those invisible gremlin videos that hopefully takes the WTF factor out for a bunch of you guys.
You know what really impresses me is that because of your shirt I just learned that you are a business owner and you still take the time to reveal tips and tricks (unlike the other 2) that give your "trade secrets" away to benefit others in the trade. You however don't have to worry about my competition as I'm in Canada. I really enjoy your videos, especially on reverse feed threading. Thanks Joe!
Thanks for watching.
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!
I learn something new every day. Thanks
Great info. Thank you for the lesson!
Great vid as always Joe!Thanks for posting,and have a nice,safe Memorial Day!
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
as always, learned a lot. thanks for taking the time Joe.
I enjoyed shooting this one. Had it in mind for a while. Didn't you win the toolbox a while back??
thats me. I might even meet you at the Bash, if you make it.. keep these coming, I usually watch all the way though...
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.
Nice video! I'm new to milling metal, but with wood I've done a bit of setup. The rule works to register from the critical point. The v block concept is new as a fixture. Thanks!
Always try to bank from the surface the dimension is driven from. Its a good practice.
some really solid advice Joe! thanks!
Great stuff Joe, love the V-block tip!
Glad you liked it!
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!
SasquaPlatypus you can pick holes up with it, or the center of a pair of jaws under the diameter size
