Thanks Ron, and to Clint for posting the pics.
I went to the local scrap yard (for the 1st time) and found a
plethora of alum. scraps. I got 2' of 1.5" bar stock and a 6"x1"
square plate for starters. I'm gonna be going back there often. :)
I'll go ahead and fine-tune my shimming for this first tool but the
first thing I want to do is to build a new tool post as I've
described.
Ron, others, would you think that al. would be sufficient for this or
does it have to be steel? The toolpost that comes with the 8x12 seems
huge. I would think that an alum. one of the same dimensions would be
fine.
Also Ron, did you have any problems with the mounted tool bit
twisting while using your set screw configuration? Clint had
expressed concern of rigidity.

I have done this with a smaller post, except that
I used set screws (or grub screws, as our British brothers and
sisters
call them) comming up from the bottom. To adjust, just undo the
retaining nut on top, lift up the post, back off the top screw
slightly, engage (run further in) the bottom screw tightly, and
replace the post as per normal. This sometimes take a few tries,
but
once the height is achieved, all is well. Great drawings, by the
way!.
Ron.
