G'day all.
Not wanting to rain on Rance's parade I have started a new topic.
Has anybody made, bought or used a rocking shim in the tool post?
The idea is that the bottom of the shim has a slight convexity and
the tool tip height can be finely adjusted by differential tightening
of the front and back screws. This replicates the adjustment provided
by the cup washer and half moon shim in the old lantern style tool
posts. Tip height adjustment does alter the tool rake but not enough
to be a problem
The one I was considering (still am :) is this one:
Seems like it should be solid enough. I like my QCTP, but it does flex
sometimes.
My experience was with the a single rocker post that held one bit on a
bigger machine, I liked it and it was easy to adjust.
I am concerned about the lateral tool rigidity, that is, the
likelyhood of the tool swinging back under load. Any comments.
Before I pick up some 50mm x 3mm flat and attack it with a file it
would be good to hear from others.
Can't speak from experience on that one I linked to, but it *looks*
good :). I need to ask them if that is for the 7x variety, at 5/8 max
for a bit, I am not sure.
Hope this helps!
Take care, Vikki (no connection to Micro-Mark).
