Re: [CAD_CAM_EDM_DRO] Re: Z-axis CNC conversion on a mill-drill: a challenge (long)

Thanks for the advice.

Having a spare pinion shaft made to order is just a thought as I do not want
to go to the extend of cutting the spline.

In fact, I am about to start reducing the existing pinion shaft right hand
side and the eccentric will be bore to fit.

With the excellence instruction in Dan's article, I should have no problem
making it to work.

Best regards,
WT

Hello,

If you're having one made to order; why not just have the same folks
modify the one you have already instead?

Another thing to consider is that the liekly "wrong" thing that
would happen is to make the shaft reduction too small or too big. So
if this happens you'd simply cocrrect that with a matching bore to
the right hand side eccentric.

Point is, this is not that hard a retrofit. There's "room" for
making (and fixing) mistakes.

AIRC, the only "hard point Dan mentioned in the article (I haven't
read it for MANY years now) is that the pinion shaft itself was a
bit hard to turn.

This won't affect you if you're having that part done professionally.

Hope this helps,
