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!
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.
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. :)
Good Evening, I found your UA-cam 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
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.
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!!!
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
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.
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.
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.
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
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.
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.
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
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.
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.
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.
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!
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.
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%
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.
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 !
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.
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.
Sorry to hear about your buddy. We have had 2 guys go out at work in the last year to cancer, young or old it doesn't care. Lots of good tips in this one.
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
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
Brilliant. I learned a lot from this. But what I want to know is, how do you keep your lathe so clean? Do you buy a new one every time you make a video?
Tolerances are OK to play with, but knowing the end use of the part is extremely valuable as well. Too many engineers stack critical tolerances just to hit a required stack height. Expensive and unnecessary.
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!
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..! :)
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.
Lots of great info Joe. I would certainly be interested in seeing how that HSS bit was ground. To us guys with only bench grinders we struggle with tools like that....I do anyway :)
Thank you Joe! Another great video - not only just enjoyable, but I am also learning. Thank you for the introduction to indi-cal. I guess if I were to make it, I could use it as general bore comparator? not just for grooves? Mine is a hobbyist shop and whilst I have external micrometers, measuring the bores accurately is a challenge... without spending a fortune on measuring kit that would be used only occasionally.
All the info needed to make one is in the original patent: www.google.co.uk/patents/US2791033 Sounds like I got myself another project :-) Thank you! Chris
Hi Joe. Great video. Using the sacrificial diameter for referencing is a great idea. I did notice that on both sides of your tool you had a corner radius. Have you considered the effect the radius would have on the position of the angled surfaces? As far as i'm aware the maths you used would work perfectly for a tool with sharp corners, but with corner rads you would be leaving 'metal on' where the angles are concerned. When you programme CNC lathes for profiling you use a tip radius compensation value so that the machine can compensate for the radius of the tool when turning angles and other profiles. I could be wrong so let me know if i've missed something. Cheers. Crispin
Hi Crispin. You never disappoint me. Your observation is very accurate. I just recently posted a video on that topic. The error is small, but it is present. In this case, this tool leaves more material on each of the 3 internal dimensions, except the major diameter of the inner diameter, so the part has material left for a final pass if you choose to hit the third place decimal spot on. Take a look at that other video if there is any doubt about the error margin and the geometry needed to overcome it. I hope you and your new shop are doing well. Thanks for the comment.
Been awhile huh? Very informative buddy. Congrats on your subscription number, I thought I was doing good with 200+ at the end of my first year!! Enjoyed this one Joe.. Razor!
Great movie like always. Thank you for all advises, I have watched all your movies. You are great old fashion mechanist . I have one question, do you have Polish roots? Because you have Polish surname. Best regards from Poland, you have in US some diffrent ways to use lathe, but I have here many inspirations to improve my shop.
Never heard of an Indi cal ..I had four years of machine shop, but it was like 15years ago. Would have though of a telescoping guage n mic, this is cool gotta get one thanx
very nice. I have interest in back cutting tools bcs I want to make a turner's cube. you cant see past the 1st back cut so just relying heavily on the dials
Hi Joe, Please dont stop your video's, your one of the best when it come's to technical training
Thank you very much. Nice compliment.
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!
Thanks. I believe the why is just as important as the how.
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
Thanks Pete.
This is a video that I will watch more than once to get the technique committed to memory. Great as always!
Internal work takes concentration and prep. Take your time and experiment with plastic so if there is an oops, the tool doesn't loose.
Awesome lesson!!...the white board with the cardboard tooling was a great teaching explanation
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.
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.
You're a great machinist and a great teacher.
Thank you. I enjoy both.
More fantastic tips and techniques, the counter bore tip is so simple and so helpful thank you, great job.
It does help. Especially helpful when you don't have tools to measure the ID with.
Thanks for the video! Love the Indical - Put that on my Projectlist ;)
Thanks for stopping by Stefan. If you make one, you should film it. Everyone appreciates your level of quality and would enjoy the effort.
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!

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

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

Hey hey! Joe's back with yet another excellent, informative vid. Thank you sir! Looking forward to many more
Good teaching video. Timeless techniques, Image, this video may be teaching those one hundred years into our future way after everyone here is gone.
Great work and instructional content as usual. Thanks for taking the trouble to make these videos.

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

Thanks Joe another great, easy to understand, educational video!
Thanks for watching.
Yet another great video Joe. You're making me look like a genius at work
Ask for a raise.
The whiteboard and cardboard cut outs is a great visualization tool.
Once again Joe, clear and concise. Thankyou
Sorry to hear about your buddy. We have had 2 guys go out at work in the last year to cancer, young or old it doesn't care. Lots of good tips in this one.
Thanks. Joes not doing well. Its breaking my heart. Thanks for watching.
That was enjoyable to watch. Your efforts are really appreciated. Thank you.
Love your videos you inspired me go out and buy a lathe.
Damn, thanks Joe for taking the time, just the kind of stuff I need to learn.
Good video. Leaves me with much to ponder (I enjoy the mental challenge).
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
Its really not that complicated. The indicator clamp may take some patience, but the end result will be worth the effort.
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

Thank you.
ingenious - excellent presentation - thanks a million
You're welcome. Glad you enjoyed it.
Nice demo of a set up I had not seen before
Tks Will
That registration diameter is a great confidence builder if the part will allow it.
Awesome video! I always learn something new with your videos :-)
Excellent. Pass it on.
Thank you Joe
Brilliant. I learned a lot from this. But what I want to know is, how do you keep your lathe so clean? Do you buy a new one every time you make a video?
Great job Joe. Could you do a video on tolerancing and how to use it to your advantage also bonus tolerance.
Tolerances are OK to play with, but knowing the end use of the part is extremely valuable as well. Too many engineers stack critical tolerances just to hit a required stack height. Expensive and unnecessary.
nice job! Thats a nice machining plastic. it behaves well with such a broad tipped tool.
What an awesome trick! Love the vids keep em coming
Blind work can be scary, but really doesn't need to be. Thanks for watching.
Nice technique, Joe!
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!
Its a simple but very efficient little tool. I've had mine forever.

Lots of great info Joe. I would certainly be interested in seeing how that HSS bit was ground. To us guys with only bench grinders we struggle with tools like that....I do anyway :)
That was done in a surface grinder. Although I could do that on a pedestal grinder, it would take a while.
Thank you Joe!
Another great video - not only just enjoyable, but I am also learning.

I guess if I were to make it, I could use it as general bore comparator? not just for grooves?
Mine is a hobbyist shop and whilst I have external micrometers, measuring the bores accurately is a challenge... without spending a fortune on measuring kit that would be used only occasionally.
You bet. If you set them correctly, they work just fine for bores.
All the info needed to make one is in the original patent:

Sounds like I got myself another project :-)
Thank you!
Chris
Very god method Joe.. Shouldn't the test indicator tip/ pivot be in line with the pivot point on the test instrument? ..
Great video. Joe would you have been able to take the single cut on the angles, if you were using steel?
I personally would not. I'd do it in several passes to reduce tool load and just so it looked good.
Excellent! Thanks for sharing!
Thanks for watching.
Impressive as always Joe. Thanks
Hi Joe. Great video. Using the sacrificial diameter for referencing is a great idea. I did notice that on both sides of your tool you had a corner radius.

212 up, another very well liked video. Thanks Joe.
437 to 1 at the moment. I'll take that.
Joe Pieczynski - always one, bro
I like the method. Thanks for info
Nice video and method. The indical looks good but limited if the internal feature is larger than the bore + range.
You would be very surprised at how versatile that little thing is. The .030 range is just the last bit of movement.
I have cut wildcat cartridge chambers with a boring bar, but this video is so well made I had to watch every second.
Thank you.
Thanks Joe - Glad you did the review on the board because my brain was struggling by then. Ok after review though.
As usual, excellent stuff. keep it up Joe
I like that tool for your indicator
I believe it would be considered an indirect measurement
Thanks Joe for another brilliant tip!
Awesome tutorial. Well explained and demonstrated. Are you ever concerned about the amount of free play in the tailstock quill?
If I keep the lock snugged, it centers better. It is a bit worn, but I know how to overcome that. You must have noticed the drill jump.
Very Informative , What kind of plastic do you use ?
That was blue Delrin.
Great stuff again Joe!
Joe you are amazing , Thanks !
Great movie like always. Thank you for all advises, I have watched all your movies. You are great old fashion mechanist . I have one question, do you have Polish roots? Because you have Polish surname. Best regards from Poland, you have in US some diffrent ways to use lathe, but I have here many inspirations to improve my shop.
My great grand parents were from Poland. My family is Polish. Thanks for watching and best regards from Austin Texas.
Never heard of an Indi cal ..I had four years of machine shop, but it was like 15years ago. Would have though of a telescoping guage n mic, this is cool gotta get one thanx
Its a good tool to own.
Very impressive Joe!
very nice. I have interest in back cutting tools bcs I want to make a turner's cube. you cant see past the 1st back cut so just relying heavily on the dials
great instruction as usual. What was the plastic? The finish looked awesome.
It was Delrin. You can get amazing finishes on this material and it cuts very well. Thanks for checking in.
Once again a great video Joe! What kind of plastic is that?
Blue Delrin. Great stuff. Its much harder than poly yet still very elastic.
Thanks Joe. Your awesome!
Great information, thanks Joe!
