Hi David, Thanks for the info, I'm just waiting for the new chuck to
arrive and time to fit it. I made a plate to bring the toolchanger
up. I now have the drill positions correct and my insert tool needed
0.4mm packing. I guess this is right, I would have liked a bit more
space above the tool as sometimes I use tools made from HSS stock and
after a few regrinds especially with parting tools they'll end up
below center.
What's the largest radius insert you have used on the Orac.
Kind Regards
John
