Re: [CAD_CAM_EDM_DRO] Max 10 questions.

Hi John,

I picked up a set of three ballscrews and nuts a while back at a sale.
Not that long, only 12" or so. So I was thinking if I made a xyz drive,
I could make some simple ways w/ dovetails, like the Sherline, but big
enough for the 1/2" or so ballscrews. OK might be a waste of time, but
an interesting project. I can probably get the dovetails cut after a
little practice, and probably figure out some gibs, but I'm not at all
familiar with this cast aluminum tooling plate stuff. Would that be
good for this project? Or why not just bolt a piece of it to the top of
the Sherline table? I made a tooling plate that way from some scrap
(cutoffs) I bought. Yeah, it's probably warped! I haven't even
finished tapping all the holes for it. I could DRILL all the holes, but
not tap 'em with my CNC'd Sherline!

You might want to answer my questions on this "K6 precision ground cast
aluminum" tooling plate might on the SherlineCNC list. I think I just
made it off-topic!

P.S.
Yeah, I LOVE my CNC'd Sherline Mill and Lathe ('tho the lathe driver/PS
isn't finished yet!!).

P.P.S Jon, please tell me offlist (don't want the word to get around)
what parts I can make for a $30,000 a year income!
