Gantry design question

[Tenson]

I think DC is talking about using pre-made ridged sheets. In that case they are already good and strong and he just needs to join them at right angles or whatever. Okay it might be a little weaker at those joins but he can probably do well with traditional methods like bolting each panel to some square section + resin.

Yes from a previous post he said using pre made sheet or box section to sandwich the aluminium honeycomb. The premade sheet will be good quality & strong so may well do the job but not as strong as if made as one complete unit. You could actually make the gantry in one quite easily using traditional wet lay methods, might even work out better with the increased weight but wouldn't be as strong.
