I've recently come into a couple of TPG lathe tooling holders that are WAY big for my little fella (11x37 Rockwell).
One was a gift from a friend in appreciation of some work I did for him. It's a monster 1.5" Valenite (SD-TML-24-64) holder. Neutral rake with largish screw through TPG carbide insert. I was thinking of cutting a dove tail in this and using it directly on my PII AXA Aloris knock off. Problem is, it's going to be a bit difficult to get it on center since the index end has a 3/8" step up. Still, I think it will work ok. Next question, how far back should I put the dove tail? I'm thinking maybe I should make use of it's rigidity and hang it out there a bit to deal with (imaginary?) cases where I need to reach way out and a normal cutter won't hack it?
The second part of this story involves (3) 1" Kennametal indexable toe clamp retained TPG holders. These are also neutral raked, and I have a left hand, right hand, and facing holder. I paid $5 each, so cheap enough to play with and “make work”. On these, I think I’ll just cut them down to a 1/2” x 1/2” tang for mounting in a regular AXA holder.
Any suggestions? I’m not sure the big one is even worth fooling with?
