Very creative, kind of turning back the hands of time when power feeds used U-joints for lot's of stuff. Milling machines. I made a dual start bolt just for fun and put it on the counter at work. People would ask "What is this?" Answer "Look closely". Nobody ever picked up on it until explained. Love the lathe, glad you protect the ways. I usually spray the Tee Shirt with water based cutting fluid just to suck up the dust and prevent burning the old rag. Thanks for sharing this.
When taps are made the centers are put into the soft blank, then it is hardened and the centers are finish ground. But you've gotta work with what you've got.
I've had some squealing at different times too. That off shore "carbide" center drill I bought was made out of marsh mellow! I was amazed at how well that hand ground old masonry drill worked
@@Lappemountainliving I was referring to the female centers in the ends of workpieces -- just looking at buying laps myself. I had never heard of them myself but saw them on a Suburban Tool video. Doing some cylindrical grinding on my (new to me) T&C grinder I am seeing ~ 1/2 thou out of round - thinking lapping centers might improve this. KBC tools (and probably others too) sells center lap holder and lapping stones.
What is your grinding wheel that you used for the thread grind? I am guessing that it is a fairly fine grain wheel to get the narrow point of the V to hold up. Very cool build, thanks for sharing.

Thanks for the comment! Thanks for watching!
Excellent video,thank a lot.
So nice of you!
Thanks for the video, you made me laugh with the center hole/divot issue 😂
Glad you enjoyed! Thanks for watching!
Outstanding!
Thank you! Cheers!
You sure know your stuff! I enjoy your videos, and I always learn
Very clever thread grinding setup.
Thank you very much!

Well done. That is a bucket load of work young fellow. BC
Thanks!
I love this stuff. Thank you so much for the video.
Glad you enjoyed it! Cheers!
Really cool project. THANKS
Thanks and thanks for watching!
for extra points - helical spiral flutes for chip clearance
That would be cool but not is possible with my equipment
I was watching intently about center drilling M2 with Carbide. Anytime I have cut bearing races, it was a squealing contest.

Very cool, what a fun exercise. I’ve always wanted to see thread grinding being done.
Glad you liked it! Thanks for watching!
Nothin but NICE!
Thanks!
Wow ! Huge project, thank-you so much for your efforts !
Do you ever lap your centers ?
Thank you! I do freshen my tailstock spindles as needed by grinding. I haven't ever lapped them

I hadn't heard of lapping tools for female centers before today. Thanks for introducing me to something new!
I'm going to check into it

Thanks!
It's a 120 grit aluminum oxide wheel. Not sure about it's bond details. Can't read anymore
What grits and type of wheels are you using? Thanks. Enjoy watching!
The wheel in this video was a 150 grit aluminum oxide. Don't know what the bond rating was but it seemed to be on the hard side. Cheers!
