Im really contemplating making solid aluminum sides to my gantry so that a....I can polish nicely, b.. I think its more rigid c.. form factor is a lot less and of course d.. I can project my gantry sides at an angle so that I have more workable room on my milling table (angle based on router used).
Is one carriage per side going to be sufficient or can I expect undesired wobble or play?
