I bought a Dürkopp 291 recently. The table is junk but I can get a new one for $100. The Varistop V720 does not seem to work and the motor spins but does not engage. It has pneumatic controls that do not work either. It is 220V 3 phase. I am interested in removing all the electronics and outing on a servo motor. Is this easy? I paid $50 for the machine. Is it worth it?
