Welcome!

I have just started the conversion of my BF20L. I will post pictures as the project moves along.

Manufacturer: www.optimum-maschinen.de
Machine: http://www.optimum-machines.com/prod...rio/index.html

Things I have done so far:
- Made Z-axis motor mount in steel
- Made block between Isel ball-nut and headstock
- Machined the ends of the Z ball-screw
- Made more room around the upper part of Z thrustbearing, and shimed the lower part of it with thin shrink tubing to snug fit
- Mounted the original thrust bearing for Z-axis under the top plate to eliminate slack.
- Made room for the Y-axis ball-nut in the base of the mill, and modified for 200mm Y-travel
- Made Y-axis motor mount in aluminium at the back of the mill
- Made a temporary housing for the controller
- Assembled the Z-axis and tested it. Lift 95kg easily (Me)
