I’ve been busy so there’s nothing new to show at the moment (this will change soon). So in the meanwhile here are some old pics of the ongoing manual lathe to cnc convertion. I start this project with used Sherline parts (a not well cared bed, headstock and tailstock I bought on ebay).
– Using the manual lathe to drill to motor mount holes on the bed. I use some custom made aluminum blocks to raise the bed to the required height.
– A custom made nut to fix preload nut (I think this is better than glue). Please note that I bought cnc motor mounts only, not the full upgrade kit, so I must adapt the leadscrew also (this was a bit tricky).
