Ok, been hunting around and thinking about router designs, but I'm at a bit of a loss about what sort of size / torque stepper motors are suitable for a given size router cutting different materials.

For instance if I have a 4'x2' bed router cutting MDF, what torque motors will I need to get a reasonable speed?

Hmm, thinking about this before hitting submit, there are a lot of variables:
What size cutter/how many flutes/cutter rotational speed/depth of cut...
What is a reasonable speed come to that :confused:

Also you can use lower torque motors if your drive uses some form of reduction gear, at a trade off of lower speed.

Maybe it would be better if people could post some information about what torque motors they use in their own machines, and what sort of speeds they can do non-cutting fast traverses. This could then hopefully act as a resource for others.

Any ideas anyone?
