Steve,
Just for your amusement, here is the current state of my ATC - I finally got some time to work on it yesterday. It's mounted on the machine, and, operating it manually, it appears to work perfectly - the forks slide on and off the tools very nicely, and the tools slip in and out of the spindle effortlessly. I hope in the next few days to get the top plate of the housing done, which will let me mount the geneva motor, and see how that all works under power. Then, it's just a matter of mounting the two air cylinders - one long one to swing the ATC to the spindle, and back to the park position behind the table, and the second to push the carousel down for ejecting tools from the spindle. I'll also need to re-make my Y/Z way cover, to make it narrower so the ATC can get back as far as possible when parked, and re-make my coolant "collar", which right now mounts to the bottom of the spindle, and interferes with the ATC.
Regards,
Ray L.
