how hard is this going to be to move while cutting

Just an inaccurate guestimation here but really only a few 10's ft/pds. The force people apply to their carriage and cross slide handwheels is mimimal.
Thats how I guage my chip loading :bitingnails:

how about a pic of where it has to fit with a few measurements

Well got some pics but fogot to stick a ruler in there, the handwheel is about 5" dia....IMG_5361.JPG
The feed motor will mount on the front and the drive will go in through the empty looking hole.

There is a bit of clearance but ideally I would rather not have large pieces of machinery extending out tooooo faaaar.

Maybe Im getting this wrong, probably I am. But if your going to power the carriage, and still using the screw, wouldnt you be better off mounting your motor on the RH end of the machine. The crosslide screw could possibly have a coupler to make the connection from the rear side? With a extension to reach the coupler out the back side.

I have been looking at the idea of mounting steppers on my lathe, for different reasons. I looked the machine over, and found the RH end for the carriage, and the back side of the crosslide would keep things neat, tidy and out of the way.

The dissengagment for the carriage is simple, and no explanation needed, the crossslide will, or would be a bit more complex, and involve more planning. I just would want motors of any kind mounted out of the way, and not on the front apron.

As allready mentioned, wiper motors, power window motors, power seat motors could be possible. It probably will be a load thing as to how hot they will run. As far as I know, window & seat motors are for intermitant use, and could be a hit and miss as to what brand will do the job.

Ive allready mentioned stepper motors, and are available for most any application you could think of for a lathe. In the USA and Canada they are not super expensive either.

The empty hole is, of course, the shaft hole for the feed clutch. Are those parts missing as well?
 
Hello Phil

Can we have an update to this remarkable piece of brainwork?
Pictures or a vidio to the benefit of Boxford and Southbend users?

Regards
