Hi Bernie
Corey ask how I did the threads and It came to me,,,

,,, I had a 2" set like the one below and used it on a blank stud stock,then put it on the lathe and got it down to the size you see in the snapshot, it's been 31 ago so it's not real clear in my head but I recall selling off the wood and die set...

to a guy that wanted to make a grape press.
To make grape juice, ya right, I think they call it wine now days

, he said many of the caps/plugs came off in the basement LOL LOL...

in the middle of the night and it was like the 4th of July in his basement. LOL LOL
