Internal Grooves and Angles on the Lathe

This video will demonstrate a useful technique for coordinating your tools for internal lathe operations. I will introduce you to the Indi-Cal and show you how it works. Take a look

[@bitjockey6265]

Your balanced approach of white board and machine time is extremely effective. Thanks for taking the time to put these excellent lessons together. Top drawer quality!

[@joepie221]

Thanks. I believe the why is just as important as the how.

[@creamshop]

Hi Joe, Please dont stop your video's, your one of the best when it come's to technical training

[@joepie221]

Thank you very much. Nice compliment.

[@outsidescrewball]

Awesome lesson!!...the white board with the cardboard tooling was a great teaching explanation

[@joepie221]

Hey Chuck. Glad you like it. I thought the cardboard tools might help. Good to know it worked. I'll store them next to my giant wooden chuck jaws.

[@peteramor9810]

Once again a great video Joe Even at 67 years old I never stop learning from you You really are a pleasure to watch Pete UK

[@joepie221]

Thanks Pete.

[@shannonstebbens6992]

This is a video that I will watch more than once to get the technique committed to memory. Great as always!

[@joepie221]

Internal work takes concentration and prep. Take your time and experiment with plastic so if there is an oops, the tool doesn't loose.

[@StefanGotteswinter]

Thanks for the video! Love the Indical - Put that on my Projectlist ;)

[@joepie221]

Thanks for stopping by Stefan. If you make one, you should film it. Everyone appreciates your level of quality and would enjoy the effort.

[@grayskwerl4973]

Fantastic video on the Internal Grooves and Angles. Really good content and camera work, and well presented. That blue plastic made it look like I was viewing a 3D CAD part. Most people could figure out about using the compound to cut the angles, but the KEY was your use of the small external counterbore to reference on the second angle. Well done sir! + Thanks for sharing your techniques + I hope you realize the important legacy that your videos impart.

[@sblack48]

You're a great machinist and a great teacher.

[@joepie221]

Thank you. I enjoy both.

[@TheMartorious]

Another great video, Joe. You always present interesting scenarios. However I think my favorite part of your teaching style is that not only do you explain how to do something but explain in excellent detail why you do it a particular way. Knowing why you should do it a certain way is so much more valuable than only knowing how, because then that knowledge can be applied to similar yet different operations. Thank you so much for taking the time to share all your knowledge with us.

[@dizzolve]

Really appreciate the attention to detail Joe. Thanks for spreading the knowledge

[@samrodian919]

Fascinating to watch that Joe, a perfect piece of teaching how to thoughtfully work a piece with out thousands of dollars worth of measuring tools! I have only recently discovered your videos and love them. Your style of putting over to your viewers, practical knowledge and skill in abundance makes it so easy to understand and watch.

[@nangidkram8652]

That was enjoyable to watch. Your efforts are really appreciated. Thank you.

[@patrickroeill8746]

Thanks Joe, Love watching your stuff, learn a lot from you

[@joepie221]

Thanks.

[@djurodrazic8566]

Great video, and as always helpful.Thanks Joe

[@TroubledTimes2024]

More fantastic tips and techniques, the counter bore tip is so simple and so helpful thank you, great job.

[@joepie221]

It does help. Especially helpful when you don't have tools to measure the ID with.

[@paultrgnp]

Even though so many others have said it, I feel inclined to express my gratitude for your brilliant videos and exemplary teaching methods. Many thanks Joe, and it is also great to be learning stuff from someone on the other side of the planet. It makes the world seem a friendlier place. Best wishes to you and your family.

[@joepie221]

Thank you very much. All the best to you and your's as well.

[@arthurtabuchi7760]

Thank You Joe ! And for taking your time . Outstanding !!!!

[@joepie221]

Thank you.

[@jerrywells8071]

Another great job Joe. Thank you

[@dfpolitowski2]

Good teaching video. Timeless techniques, Image, this video may be teaching those one hundred years into our future way after everyone here is gone.

[@johntenhave1]

Man that was a tour de force! Great methods and an excellent explanation. The counterbore was so obvious - after someone shows you. That idea is going to get a thrashing in the future, for sure. Thank you.

[@joepie221]

No need to be blind if you have a choice. glad you liked it.

[@kwik440]

Joe, THANK YOU SO MUCH !! For taking the time,and effort to make these videos, they are AWESOME ! I learn from each and every one, and cannot thank you enough, I have learned so many tricks watching your videos.. Simple, straight forward,and just common sense applied to machining.. I have stepped up my game 100%

[@joepie221]

Glad to help.

[@StuartsShed]

This is a masterclass tutorial. Not just the demo on the lathe, but the explanation on the whiteboard with the cutouts really clarifies things - thank you yet again! This library of tutorials is a knowledge gold mine!!!

[@joepie221]

Glad you enjoyed it!

[@brianwarburton4482]

Excellent video. As always.

[@rickbradley5085]

I always learn from you, love the front bore idea. Thanks

[@NH3rrm4nn]

Hey hey! Joe's back with yet another excellent, informative vid. Thank you sir! Looking forward to many more

[@bobwas4066]

Good Evening, I found your KZbin channel a couple of weeks ago. You produce some of the best machining videos on the web, the content is superb. You are an excellent teacher, keep up the excellent work, Thank You Bob Wasiczko

[@532bluepeter1]

Did I like it? Yes, thank you. I loved it. I never knew how to do this and have always fought shy of undercuts but now with this information squirreled away I need no longer have fear. I just hope that my wee Hobbymat does not chatter too much. Thank you very much for sharing the benefit of your great experience.

[@BluesDoctor]

Another great tip.... I look forward to your future videos, you are doing a great service for all who follow.

[@joepie221]

Thank you. I appreciate all you guys.

[@vbidou17]

Thanks a lot Joe ! That video required some preparation and time but its a gold mine of tricks for this operation. Best regards from France.

[@joepie221]

You hit that on the head. It took more prep than the others. But I liked the final cut. Thanks for watching.

[@JBFromOZ]

Cheers for sharing Joe!

[@johnmcdonnell6109]

Thanks Joe! As usual, cool and informative video!

[@billyharrison4126]

Once again Joe, clear and concise. Thankyou

[@whitecaps775]

Damn, thanks Joe for taking the time, just the kind of stuff I need to learn.

[@carlpenney901]

Love your videos you inspired me go out and buy a lathe.

[@ChrisB257]

Know what Joe - I got an Indi-Cal ages ago and put it away. I never actually worked out the best way to use it! This was a classic video and I am super thankful for you making it.Once I get back into the shop I will put it to good use.! One thing you got, predictably, was a boatload of chips:) That special tool must have taken an age to grind! Lighting and camera angle worked great later on. Absolutely magic. Inspired. :)

[@joepie221]

That was a 5/8 cobalt blank. Its an old tool I take good care of. Thanks for the comments.

[@cgrobe21]

I want to thank you for bringing your high level of knowledge that you gained from the industry from years of seat time in advanced fields to youtube. Your time is much appreciated. Chad Cosgrove Home hobbiest

[@joepie221]

And so many topics to cover too. Thanks for stopping by.

[@CharlieParker1959]

Great video Joe glad to see you posting again.....

[@joepie221]

Thank you. Nice to be back. I have several videos on the block right now. I just have to clean them up and upload.

[@GadgetBiker]

Very Cool. I always learn something watching your techniques.

[@joepie221]

Mission accomplished !!

[@bigboi-xo3xj]

That was amazing. I'm a beginner machinist and the information you teach is great.

[@joepie221]

Thank you very much.

[@thisstuffido9141]

Professor had us make a part just like this in a ME class in college. A very valuable exercise. Thanks for sharing and for the clear explanation, as always.

[@longlivepunk]

Joe, this Indi-cal is awesome, I wish I knew it existed before! For the jobs I do at work this will make life so much easier! We have dial bore gauges, ID calipers, etc. But having one of these in my own tool box will be invaluable! Thanks!

[@joepie221]

Its a simple but very efficient little tool. I've had mine forever.

[@markfulmer8501]

Hi Joe- fantastic video I like the way you cut in with the white board and the large cutting tool for the visual slow learners like myself

[@zumbazumba1]

Thank you Joe for all your time that you put in creating videos like this,and sharing with us your experience and secrets of the trade.Your show us how to make odd things and be precise.I find your videos helpful ,like that exact taper degree setup video you have. Sometimes its harder for me to understand imperial units since my whole life i have been using metric ,so if you could make conversions to mm if its not hard to you. Other than that keep a good work,you helped a young machinist to get better and for that i thank you !

[@joepie221]

Excellent. Pass it on.

[@robertlewis4666]

Thanks Joe for another brilliant tip!

[@pwpia5461]

Great job Joe....that was some "curve ball" when you changed the rules to "inside" the part...needless to say I stayed for the last pitch. Keep up the good work and sharing your skills with all of us who are machinist. You sold me on the Indi-Cal....I'll be having sack lunches for a few months with this purchase.

[@FredMiller]

Had to watch it twice but I got it registered in the ole memory now. Thanks for a really interesting segment! Fred

[@joepie221]

Thanks Fred.

[@AlabamaTree]

Impressive as always Joe. Thanks

[@dennisthatcher4384]

Thanks Joe, Wonderful tips and great teaching style as usual. I fought with an internal grease boss and o ring groves and finally cobbled my shop vacuum close to the back of the spindle through hole to clear the chips (Magnets and duct tape). Looked like hell but I could see what I was doing and it worked. I'm sure you could make a professional looking rig for filming internal work, It helped to see the actual cuts in progress.

[@ianpendlebury3704]

Great work and instructional content as usual. Thanks for taking the trouble to make these videos. Ian.

[@joepie221]

I hope they help.

[@larrysperling8801]

great lesson prof joe. thank you

[@minasianjohn]

I know this reply is way past your presentation date , never the less your approach is a great way to bore the inside diameters and angles. Well done Joe, keep your educational videos coming. John

[@lesliebird5621]

Blind work can be scary, but really doesn't need to be. Thanks for watching.

[@timmartin8987]

Great information, thanks Joe!

[@williammeyer9616]

Your videos on professional techniques have saved me from a lot of aggravation. They helped me with seeing alternative methods and understanding why what I am doing either did or didn't work. I'm beginning to see even what might or might not work. Deciding what tools a worker really needs vs. luxury vs. Good value vs crud might be a good topic, but as much as I might think it would be valuable, I would ask that you not let it compromise the problem solving and technique content. Often proper machinist logic seems even from my less than a year of experience to answer many questions. I look forward to seeing more of your experience and machinist logic. It comes through in a way that some other internet teachers don't. Maybe it's because you present it in a general manner that applies all over the place. . I've been watching many channels and you're one of the best and the first one I am subscribing to. Please keep it up. Thank you for sharing your knowledge.

[@joepie221]

Thanks for the feedback and welcome to the channel.

Excellent presentation and explanation, thanks. Peter

[@joepie221]

Thank you.

[@mikekeele1533]

Joe, you're an inspiration every time you make a video..i'd never have thought of setting the internal dimension at the start, on the outside. And i will probably never have the courage to rely on my setting the 30 and 45 degree angles for the intermal. Sorry you missed the Summer bash

[@joepie221]

I'll be there next year. I'd like to bring my son, but his school schedule was a wild card I wasn't going to mess with.

[@mikekeele1533]

how old's the boy? i took Keith Rucker and about 6 or 7 others to what is arguably the best ice cream parlor in the world.

[@joepie221]

He's a junior at Texas State. 27. We both still enjoy Ice Cream. He took some summer classes to accelerate his curriculum and had to decline my offer this year.

[@mikekeele1533]

Well maybe, we can show him a good ole welcome to So Cal next year. The next week, Stan told me he was already planning for next year, so i expect big things. This year's lunch was to die for, even by Texas standards.

[@HaraldFinster]

ingenious - excellent presentation - thanks a million

[@joepie221]

You're welcome. Glad you enjoyed it.

[@rodschweiger4195]

Joe, Great video as always. Please consider doing a video of mahing an Indi-cal. A measured drawing would be a great help. Making the leap from tool user to tool maker is so cool.

[@quinka2]

Superb Joe! I cut a blind in between metric and English thread in 8620 steel 4 inches deep and could not see where the tool touched the material, so I used the cross slide dial to get my touch off point, then I plunged the thread and used the customers mating part to get the finish cut. I made the part complete in 3 hours (and it had 2 more external threads and 3 bearing diameters and was 11 inches long) it was not available to the customer even at $6,000.00, so I made 3 of them! What a job!!! The thread diameter was just under 11/16 and fine thread. I would have been much better to make a bore like you did for a measurement! We learn every day Joe! Thanks for all!

[@joepie221]

Toughest thread I ever did was a 13" 32 pitch OD and mating part ID thread for a telescopic acid shield in aluminum. Oh yea....the wall thickness was less than .035 on the entire assembly. I actually enjoyed the challenge.

[@roughrooster4750]

[@ianjoubert7505]

Thank you Joe

[@customcutter100]

The whiteboard and cardboard cut outs is a great visualization tool.

[@gh778jk]

I am making me that indi-cal ! Seems like the ideal tool to get the bore of a model steam engine measured in a very precise manner... A few members of some decent grade steel... a light beadblast, some nickel-plating... and it will look the works ! Thanks Joe, great vid! Paddy

[@joepie221]

Its really not that complicated. The indicator clamp may take some patience, but the end result will be worth the effort.

[@gh778jk]

Joe, yeah, I figured it wasn't rocket surgery...I made/copied some 'addons' from pictures and drawing out of the Starrett and B and S catalogues, in the past. I now set up a small corner where I can Chrome, Nickel, Copper and Zinc plate... If you give your work a light glass-bead blast (not on the true/reference surfaces of course) you get a really nice matt-like finish and your home made tool looks really professional... I have taken to engrave " Green and Blunt" in these homemade things ....analogue to Brown and Sharp... Cheers Paddy

@@joepie221 I am just a very fascinated viewer of machining videos and I very much like and enjoy your style and methods. I am thinking about purchasing a combo machine in the near future as I am very limited by space, single phase power and budget. It is going to just be for hobby and repair work on my other toys. For years I have just taken stuff to a machine shop to have my work done but I want to do my own. Sorry for so wordy a reply but thanks for the reply and I look forward to more videos.

[@joepie221]

Thank you.

[@StraightThread]

Nice technique, Joe!

[@boomstra]

Joe, at 5:20 min I remembered your vidoe of early 2018 about the cosine error. So in this case the lever must me about parallel to the surface of the tip. The angle of the lever to the indicator doesn't matter. It is a lever indicator and thus designed to measure under different angles. You can rotate the lever to adjust it so it is parallel with the measured surface and there will be no cosine error. You know that..! :)

[@zHxIxPxPxIxEz]

There will allways be cosine error and deflection. Esspecially with Am indical. This doesn't mean it's inaccurate, however if you have .015 to go I wouldn't dial in .015 Do .0075 and see if it behaves right.
