Cheers Martin,
i haven't spent any money yet. i have collected step motors, power supplies , linear shafting qty.2 ( O.D. 25mm X 900mm Long) , 2 bearing blocks to suit ,15 mm profile linear guides qty. 2 ( 600 mm long). and 2 linear bearings to suit.
these parts were surplice to requirements when the company i worked for closed down. i basically decided to build a cnc router that would accommodate these parts with a view to getting the m/c up and running. the ultimate aim is to m/c a guitar body and neck. so i think a m/c size 4' x 4' would do.
