You can, if you have a welder. If not, what is the price difference between a welding unit and a tube of epoxy?why couldn't you tack weld them instead of using epoxy, to assemble the light scrubbers
Somebody did it with a cereal box (I think?) in an earlier post. But, I don't think it would have the structural integrity to hold up to the least amount of stress. The corner guards are cheaper than aluminum stock and easily cut and assembled; and would have more rigidity compared to cardboard.could this be done with card or paper?
hth!
