Here we go, some photos of my conversion. I hope you dont mind the thrad crash Jon, but hopefully they will help you out too.
So, in no particular order, the z-axis servo is mounted to a ali plate, which is bolted ontp the back of the lathe. I have used nuts as standoffs to align the pulleys. The large ali block in the foreground houses 2 deep-groove bearings - thrust would have been better, or even angular contacts. this conversion was done on the cheap!
The z-axis nut is delrin, 3" long, which should stop it from "squishing" undeer pressure.
Next is the extension I made to hold the x-axis bearings. the top was milled with my hacksaw and files to allow the x-axis to slide over the top. The leadscrew was replaced with a longer one, the nut was replaced with a bronze nut, and again, 2 deep-groove bearings on each end.
And next, the x-axis motor is mounted to an ali plate, which is offset to allow the motor to travel below the bed. The ali plate is mounted to a round ali block, which holds the leadscrew bearings. This, in turn, is bolted to the cross slide.
Lastly, a very simple control box holding two gecko 320's. Nothing fancy, simple engage/disengage switch, and power on/off.
Hope this helps. but like I said, could have been better if I had a few quid to spend. Perhaps when I get the wheels a rollin'
