Oh crumbs. Here we go!

Learning myself so could be wrong but from what I have seen & read ally plate on it's own won't be enough for the gantry & you will need some extrusion or box section fixed to it.

Hey Martin, yes I think you're right. Jonathan also mentioned it in an earlier post on this thread. I plan on bolting a bit of steel box section across the backplate of the gantry to give it that extra rigidity. Do you know if that applies to the sides too?
