while i wont rule that out my mission is to make the whole machine bar a few bits of steel plate i might need from just the 2 lengths of 50x25.

i acctually had an idea last night, i've been struggling since realising that the bearings are only 45mm to only use 50x25 as this way there is no spacing between the y axis rails and y axis bearing mounts, basicly the machine would rub against itself, where as when i used the 60mm across the y axis bearing mountings it spaced enough away from the rails.

now my choice was to stick the the 60x40 just for this bit, but even ordering to pieces cut to length is a big jump in cost that i dont really want/need.

so my idea is i'm bound to have some scrap pieces of 50x25, and thinking about it i could quite easily cut one side off a section and leave myself with some 3mm shims that i could use to space out my problem
