Comments sought on new build: A CNC Router for RC Gliders and Planes

Finished off the last of the cleaning up of the epoxy this afternoon.

Worked out how I'm going to get the rails square. We have a 24" Mitoyo caliper which just happens to be the correct length for the spacing of the rails. I've drilled and tapped one hole (after shortening one rail to the correct length) on one rail as the base reference and ill clamp down the other ends using the caliper as a measuring stick. I'm then going to use the milling machine to mill a piece of 10mm Ali plate down one long edge and both ends, then ill drill mounting holes for the carriages and using squares off the reference face of the carriages make sure all is square before tightening down the plate. I can then use this to slide up and down to get the rails parallel and then mark and drill the holes.

Anyone see any issues with this method?
