Hi all,
I just made myself a Die holder to go in my drill chuck (tailstock). I was my first effort at true dimensions in steel. It turns out all it took was; quit being a sissy and give the carbide insert something to chew. I did 1mm cuts and voila, good chips, nice finish and no vibrations. Only one thing I did not think of: when boring to true dimension I probably should have waited for the piece to cool down. I got a 0,10 mm play after it cooled down.
The holder itself was made from the top of my head, thinking of some designs I've seen on this site. I filed a flat for a grub screw and will drill and tap in my mates pillar drill. (I have no 4 jaw for this lathe).
All in all it was a good day in the basement ;D
