I have spent allot of time on the build logs so far. Im seeing allot of parts that require a mill and to me that dsrives up cost and complexity. Im sure it increases strength but above my computer I have K.I.S.S which is proving handy :D

If you made the gantry out of steel or Ali extrusion you wouldn't need a mill.

A couple questions where I cant seem to find the answer..

When the epoxy is applied to the steel and sets, to bolt on the rail im assuming you just drill and tap? otherwise that must be a very fiddly job getting all them nuts down there haha

Depends on the thickness of the steel. If you've read Eddys build log you'll see he glued in 6mm flat and drilled and tapped into that...

carriage space seperation, Is there an optimum distance between the bearings? im assuming the further apart the better but that obviously reduces work area so i guess there is a happy medium somewhere, right?

Pass...i settled on 200mm as a good compromise between losing cutting area and strength...
