a Steel Box Section Build with SBR20 & Ballscrews Plus a few questions

[grain_r]

Hey colin

Sorry for the Delay in replying. I have given myself room to move components for small adjusting of plates which is lucky too because as previously said I just cant get the holes as close as I would like. although I centre punch and then centre drill and then go larger but I think with my newer drill press it has got better. But i have made 6mm holes in the plates that bolt to the m5 tapped holes so that will give me a small amount of movement.

I have a dial indicator to get as close as I can although I need to find a long enough straight edge to trust and then using the Vernier caliper too.

I will then be able to then flatten the spoil board once everything is running so it won't matter if the machine is a small part of a mm out because it will al be parallel with itself and also the work piece.

Well that's the plan anyway. I will be using Epoxy for the rails to get the top rails flat running a channel between the rails and this will then self level.

i think then it will be a lot of fiddling about to chase every last 0.0 of mm

I would be great to have those known flat and precise equipment of the manufacturers have but money would never allow for it sadly.

thanks

Rob
