Hi guys,
In my first machine i used 12mm threaded iron rod for transporting the gantry. The nut is made of a copper-zink alloy (Messing, dont know the English word).
It works, i compensated backlash by means of two springloaded nuts, no fancy stuff. But it's no ballscrew.
So i started thinking of using Teflon. Dont know the English word either, but it's the stuff used in cooking pans. (duh... )
Anyway, did anybody recently try this with teflon? It's tough, it's wear and heat resistant and it slides like...well, more like a ballscrew than copper-zink does.
Being tough, it might be hard to drill accurately, and tap 12mm thread into the hole.
Anybody want to share thoughts about this? A beer for the first reply! :cheers:
Thanks,
Ed.
