I just bought the computer yesterday, and I already have a mesa 5i25 to put into it. With 2 ports available I ought to be able to make that lathe do the sailors horn pipe. But progress is slow. Putting the X motor on the back of the apron changes the rebuild of the x drive into making a new shaft to fit hard bearings hidden in the screw in sleeve that carried the old x handle, so I ordered bearings last night, and will make a new 1/2" A2 shaft with that compression nut to grab the screw on one end of it, and more thrust bearings in the outside end, and a couple timing pulleys to connect the motor to it. I'm making the motor mount plate to carry a 425oz 8 wire nema23 I have, and if its not stout enough, theres room and mount holes drilled already for a short nema34. That 1600oz/in that couldn't handle the mills Z weight, will be used on this Z. I had it spinning 2850 revs laying on the table yesterday, and this carraige moves easily. I've a 1450mm long 2505 screw in a paddle boat someplace in the middle of the pacific for the Z drive. The left face of the headstock has been cleaned out. the Z motor will mount in the old QCGB's position, as high (I took the rack off) and as close to the bed as the nut flange allows. Less swarf on it there. I hope... That kilowatt induction heater module checked into the local PO at 7:36 PM saturday night so I'll be at the PO in about 3 hours to see why it wasn't delivered yesterday. So I'll be able to harden the stuff I make out of A2. Picked up an 80 gph water pump for the coil cooling yesterday too. Hook up hosing I have in the basement from my water control efforts. > > How much do you want for one of those Gregg? > > There is a button to "order this printed".
