MACHINE SHOP TIPS

[@markkoons7488]

I think you're really a good teacher. Thank you.

[@mrpete222]

Thanks

[@fredwild190]

In a pinch, I mounted a hss moulding cutter as a form tool in my mini-lathe and turned a radius on the end of a 1/4" brass rod. The profile is slightly different, but it served my purpose well enough. You gave me the idea, and thank you very much.

[@mrpete222]

👍👍

[@TheDisorderly1]

Another great video Tubalcain. Congratulations on 10 million views!

[@danbreyfogle8486]

This was very interesting. I would love to have that ball end turning device for my wood lathe, lots of uses for that. I can get a fairly accurate sphere on the end of stock but it takes a lot of messing around to do so. Now off to part three!!

[@ManicMater86]

Great video I love the Paul Harvey sign off at the end.

[@mrpete222]

👍🇺🇸

[@1-shotslinger108]

Genius how you indicated the ball mill travel. Going to use that trick. Did not think of that.

[@Thomas_Slaughter]

thank god you have all these videos. now i could go to work and show some of the machinist how to you the engine lathe to its full potential.

[@lewda1000]

You could also use trigonometry to work out a depth of cut and a offset from the centre to create your radius using a slot drill and depending on how small of an increment you are willing to work out gives a better finish then polish it up after

[@TheTarHeelTom]

Great video. On the form tool, I would have picked three other radii and put a form on each corner of the plate. 4 tools for only a few minutes more effort, and no more cost. Of course, I'd have used my number stamps to mark the size of each corner.

[@edl5074]

Great video as always

[@TXKurt]

Thank you very much - Looking forward to the videos on heat treatment!

[@paulpannabecker4641]

November 2014 ? I had to do a double take on the calendar but this will still be good next year as well!

[@RyanBlace]

Congrats on 300 videos!

[@RJB_FixinStuff]

Awesome as always! Thank you again for all you do!

[@mrpete222]

Thanks for watching

[@not2fast4u2c]

Another Great lesson on machining Thank You

[@mikeadrover5173]

As always, thanks’ for taking the time to make this video! And I support this site. ~M~

[@FinalAnimus]

If you bought the tool perpendicular to the workpiece (if it is perfectly 1.000) and had zerod out the crossfeed when the tool just touches, would that be an effective way to set it up to cut that 1/2 inch radius?

[@YoeyYutch]

That's a neat tailstock indicator.

[@oldSawyer]

Since you mentioned setting the form tool just below center to help cut down on chatter I thought I would suggest maybe making the tool about half its original width. That way it wouldn't hang out so far part the side of the tool holder which would also help with the chatter. Another thing we often did in the factories when using form tools was right after sharpening them we would take a carbide tool and lightly drag it across the cutting edge, ever-so-slightly dulling the cutting edge. Believe it or not, if the tool is 'Too Sharp' it will chatter real bad, and dulling the edge a little will make them work like a charm. It takes a delicate touch though. If you dull it too much, then you end up having to re-sharpen it and start over. That really makes a difference when form cutting aluminum which likes to grab the tool.

[@mrpete222]

Will try that--next time I use that setup-thanks.

[@lastmanstandingwtsht]

Very nice,heat treating cant wait !

[@robertallnutt3717]

Excellent as always, thank you.

[@kerrywil1]

another great video. thanks

[@MrUbiquitousTech]

Great info Mr. Pete! Very insightful, I like how you make those forming tools! I've watched those other videos where you've discussed heat treating/annealing, but a could of times you've mentioned doing an in-depth video on the process. Is this still on the drawing board? I'd find that very interesting!

[@mrpete222]

+ShysterLawyer Still on the bd

[@MrUbiquitousTech]

+mrpete222 Ooops, in my comment up there "could" should be "couple". Thanks Mr. Pete! I'll look forward to it when you can do it, I know you're a busy man!

[@belgrademachine]

Another great practical video. Thank you!

[@joshuajones3728]

It's like listening to nick offerman talking shop with you :D

[@hakimmic]

Very informative video. Thank you.

[@madewithscraps]

I find that you can turn a "completely round" ball by drilling and tapping the needed threads for ball mounting on your project in the beginning. 1st-Face the front end of stock. 2nd-center drill-3rd drill and tap for required thread size and depth. 4th-turn the radius as was done in this video. 5th-Part the opposite end at your measurement (appx 50% in length of the diameter size). 6th-Mount the turned radius on your matching mandrel and turn the other 50% of stock as in the primary stage of this video. Actually faster for me this way when I want a round or multi-shaped sphere.

[@miguelcastaneda7236]

we used to make by hand rough hand grind...have a block to hold with angle of clearance 5°steel ..15 ° alum....then clamp in go drill press piece of rod size of radius..lapping compound..take all together 15 min...once you have your holding block made

[@ronwhittaker6317]

love , teacher

[@outsidescrewball]

Great instruction...thanks

[@k5at]

Like to see a video on setting up the ball turner.

[@j.lucena5486]

Very good lesson.

[@mrpete222]

Thanks for watching

[@chuckbear1961]

Nice job My old Logan lathe is a little off to

[@chimpfoos65]

How big of bar stock can the homemade radius tool cut that you have in that one how to cut a radius up to 4 inches maybe

[@mrpete222]

Actually, I have never tried it on large stock. Give it a try but run it at very slow speed and see what happens.

[@NOBOX7]

tublecain your awesome , could you tell me the name of your step 1 learning video ? i dont even nohow to zero in my stock .

[@SUNEELKANDA]

Hi, this side Suneel Kanda from India, Agra the city of Taj Mahal, How to make radius on grinding wheel of 0.50mm or smaller

[@DavidHHope]

I searched for video on turning an interior radius, but, apparently my "Google-Fu" is weak. Is there one?

[@mrpete222]

No

[@mikimexicali]

Tanks again nice vid. Im the first i tink and im mexican! Haha do someting with the mill please!!!!!!!

[@krazziee2000]

good video, good info, thanks

[@darthherald2564]

I learned a method of roughing the shape with a parting tool and then filing it into shape. It's time consuming and there is math involved, so I would much rather use a form tool.

[@Glofilter]

I've been looking around, but have come up empty- I need to turn a internal convex curve- not concave. I'm turning an outside housing for a turbocharger compressor. An outside convex curve seems simple, but how do I do it inside? Thanks.

[@mrpete222]

+Glofilter Thanks for watching!--sorry, never did a inside one

[@alfredochavez6575]

mrpete222 ,

[@perdidocamaronero5400]

I have thought about this also. Turn the tool upside down and run in reverse maybe?

[@caspermijacogeo6750]

I use to free hand all my radii over 3/8 ths.

[@buzby1952]

Hi there please accept a little tip on cutting aluminium use paraffin it will cut a lot better than water/white-water. all the best buz

[@loudhowl]

Tubalcain.... you must be a traveling man

[@1-shotslinger108]

My circle cutter is from an eBay kit and it blows .I already made a thicker aluminum swivel tool holding piece .The work sucks the tools down It was a 50 kit including handles and instructions that won't work unless you add a set screw. Handle slips too and I oversized the pins in the kit up to 1/4".Piece of crap I may duplicate the design in steel 1/2" thick

[@MrBest4tyres]

hi mr pete if you could make me the tool for internal and external radius id buy it off you

[@kerrywil1]

Do you have any interest in doing a video of face milling and fly cutting? I have done and and would love to learn and it and positioning the tool in the fly cutter. Thaks

[@htral]

"November 2014"?????

[@perdidocamaronero5400]

I just saw this video from six years back. I had a brainstorm and wanted to radius some aluminum stock and I hand ground a couple of tools then I spotted my router bit box and eureka. I whipped up a simple tool holder and locked one in and got it on center and it worked. I haven't put it against cold roll or stainless but it cuts aluminum like butter. i.imgur.com/PYe7Z0p.jpg

[@mrpete222]

👍👍

[@elmerfudd2you]

I'm curious what you think of google plus and the situation as it is? please consider doing what I did. set your videos to private that way no one can see them anymore and google cant make money off of them. this will hurt google in the pocket book! if we can get enough serious content providers like you to do this we may have a half a chance. see my video that explains how I did this on my main youtube page. also share this information so others will also make their content private together we made youtube what it is and together we can bring it down!

[@MyShopNotes]

Thanks for the videos MrPete. I had the pleasure of watching my friend turn some wooden balls using the same technique, a slightly larger radius though. Here's the vid kzbin.info/www/bejne/nZuxq6aeaMaHrJo
