Jon.
Yes, anti-backlash screw should make it very rigid - so probably I will go
this root.
I checked your products and they seem to represent a great value for the
money.
Its amazing what people can have now for a few hundred dollars. I was
looking
at the recent KBC tool flier - Basic milling machine is $6,625 Cdn.
The same machine with 2 axis CNC - $25,000 Cdn. I think, using your staff,
the same
conversion can be done within $10,000 Cdn. Not a bad saving!
