Hi,
I'm new to the list and just about to start building my first CNC
machine.
A lightweight 3 axis machine for working circuit boards and foam for
lost foam casting.
I wondered what others did for leadscrews.. To keep the cost down, I
was thinking of buying a threaded shaft and then using a section of
shaft as a core, usng my injection moulder to injection mould Nylon
Split Nuts. I found some shafting on eBay

or am I losing so much by using plastic nuts that I would be just as
well of with cheap studding?
The same method should be ok for simple slide blocks for the ways.
Thoughts? is this a crazy idea ?
