I am trying to make a milling table for my unimat from a piece of cast iron. The dimensions I get off photos on Ebay just don't look correct. Does anyone possibly have the dimensions of the table?,

Re: DB/SL optimum power?
I've just done my SL up with a 24v 150W motor and PWM speed control. It's AMAZING! I'm going to document it all once I've sorted out my drive pulley.

Re: DB/SL optimum power?
