@@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.
Really cool project. THANKS
Thanks and thanks for watching!
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!
Excellent video,thank a lot.
So nice of you!
for extra points - helical spiral flutes for chip clearance
That would be cool but not is possible with my equipment
I love this stuff. Thank you so much for the video.
Glad you enjoyed it! Cheers!
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
A double start should have a taper twice as long to cut the same thickness chips. Its about the number of points to cut a given thread depth.

It's a 120 grit aluminum oxide wheel. Not sure about it's bond details. Can't read anymore
