Hi,

I'm trying to find suitable materials to make a frame approximately 2500x1250mm to support a light gantry (5kg Inc router).

Originally I had planned to fabricate the frame from 50x50x3 rhs but I'm rethinking using aluminium profile, maybe 40x40 t slot or something, not sure how rigid it would be though.

Does anyone have any ideas or experience in building a table so big please? I have found UK suppliers of the extrusion but if it needs lots of bracing I fear it will cost too much :(

Any tips or links would be much appreciated.

Thanks very much,

JJ
