Re: Lead Screws...where do you get them???

QUick couple of questions related to this topic:

1. I have a mill-drill (the so called "Rong Fu" kind sold by Busy
Bee Tools in Canada). Is anyone aware of a ball screw kit
specifically for this mill (preferably one available in Canada)?

2. Can anyone recommend a "bolt on" CNC kit for the mill-drill? I
admire you folks who can build a full CNC system from scrath, but I
think that's a bit over my head right now. I mostly would like
something I can set up on the mill drill relatively easily.

Thanks,

Chris
