My friend has a lovely Ikegai manual lathe with the two speed tailstock, its great for drilling, wind in on low gear and its a breeze, haul out in high.
As you say however, not likely you will use it much for CNC but still you could do drilling by manual means before letting the CNC rip :)

Any idea what kind of rapids I should be able to get out of the proposed setup?
It may not be rocket science, but try to send a man to the moon with out a machinist.

With Mach dose the PC have to be booted before powering up the rest of the equipment or can the PC get it's power from the same disconnect?

The voltage will determine the RPM of the motors so you should be able to work it out roughly from there. Your 110v DC in may come out of your amps at a bit less than that so it wont be an exact figure but I would think if work on a 90V for the motors you will get a good idea of what you will get. What are the motors ratings?

Not quite sure what you are meaning regards the power, the way I have my machines is they are fed from a single supply, 3 phase 415v in my case, and then all hardware is powered from that. I have my machines so E-Stop kills all drives, motors, hydraulics etc.  PC, PLC etc are always live unless main cabinet switch is off.

Hood, OEM Servos are S.E.M. DC Perm. magnet.
Type: MT 30M4-59
Constant stall torque: 3 NM
Max RPM: 2400
Volts: 142
Pulse amps: 30
Tacho: 9-5/1000 RPM

Ya, thats what I was asking about the power. I was thinking of building the PC into the control panel and that would mean the it couldn't get power until the 220VAC 3 Phase power is turned on to the machine.

Any idea how the PC would do in there with all the high voltage flying around? I'm kind of worried about about that part, but it sure would make it nice to have it built in and the CD and floppy drive excess on the front of the control panel.

Let me know what you think.

Well at a conservative estimate you should get around 1500 rpm but probably more, just depends what your drives will actually output.

I have the PC in the cabinets on my machines, see pic of the mills cabinet, PC is up top in the pic.

Looks good Hood. Got a pic looking down at your J1 breakout arrangement ?
It looks very space conscious but difficult to get at. ? ?
Nice !

Its a bugger to get a pic of the cabinet as it is close to the wall,  that pic was before I had finished wiring. Will have a look see if I can find a pic of the connections, but they are easy to get to.

Ok, didnt realize. Dont bother, just curious. Are they just term strips, or pcb's with terms?

Heres an out of focus pic.
The Bridgeport will have these ;)  http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=200576246680&ssPageName=STRK:MEWNX:IT
