hi guys,
im looking at making an 8 x 4 ft plasma table, thinking of profile rails for y and z but struggling with price / availability / shipping of 3m lengths so ive been back to look at dual v again.
ive spoken to a supplier and they are talking £70/m for the rail!
im aware that the mechmate chaps do alot with profiling angle iron to make rails but given mine is a bespoke design and it wont affect any other dimensions could i not just put the angle face down so the two legs rest on the surface and the v wheel runs on the sharp corner of the material.
did i read in a post from one of the admin who has done this? has anyone else?
would it be advantageous to use stainless or aluminium for better dimensional accuracy?
also is the torchmate system of using bright steel with a plain roller bearing running top and sides worth considering?
id be greatful for any input/experiences
thanks all
