Has anyone any information on this machine please?

My machine stripped the brass motor pinion, which drives a steel gearwheel, in the first few months and it stripped the lead-screw nut on the Y motion soon after. I made a new bush for the lead-screw nut on the lathe.

Backlash on all motions was not impressive from new.

I have always suspected the RPM and today measured it with a tacho-generator. It is 600/1750 instead of the advertised 1000/3000. That is not enough for milling Free Cutting Steel with a 3mm endmill.

Does anyone know of a supplier of replacement steel pinions?

Is it possible to adjust the electronic controller to increase the speed?
