Looks real good Sam.

You have option # 2 now. Option 1 sounds like no option to me. Backlash must be taken up immediatly after a direction change else the tool path will not be true. Have you got backlash set up on your machine?

Sure you can. Please do post a link.

Yes it is.  :)

Rc, I use Autosketch. It is inexpensive and I can open most any file, not solids of course.

Hey RC,
    I have lots of ideas on R8 tool changers. Will try to make you some drawings. One way Poppabear suggested in Galesburg that sounded good for the draw bar was this. Get a large collet, 7/8 or so. Make toolholders with a 7/8 shaft. Put a nut on the drawbar, then the collet. once you have the length figured out, use the nut as a jam nut on the collet and locktite. Can use an air cylinder to actuate the drawbar. Since you will now be going in a collet, the key is of no concern or orentation. Can make a disk type tool holder to hold the tools.

Phil,
   I did the knee on mine. I love it except for the speed. The only way I would do the knee again would be to use an air assist ballscrew and a big servo for speed. You could just hang a motor on the knee for tool length comp. and setting your work 0 and drive the quill for your z. They both have their benefits. The quill can be driven much faster for the same money. If you use the knee, you can lock the quill or still use it by hand for things like tapping.
