having a wee look at this tonite-

for the y axis... was thinking of using the 80 x 120 ali extrusion... with one 20mm hiwin rail mounted on the face

a bit like this-? Attachment 5561Attachment 5562

dunno if the 2 rails are over kill? for a router that'll mainly be doing sheet materials like ply and mdf with the odd bit of polycarb etc....

the z'll be hiwin type again with ball screw-
