Bridge Gantry Profile

[~andy]

Well If you have too much money then go for it.! . . It will work that's for sure but it would be a dumb thing ignoring better cheaper design don't you think.

I'm not ignoring a different designs outright. Just looking at the options.

Problem with this stuff thou other than cost is it's light duty thin wall stuff so could resonate or twist/flex in longer lengths.

I can't tell with extrusion, and I don't know enough to be comparing section modulus and moment of inertia figures over other designs. It's a very strong cable tray really after all.

It won't allow much easier build because there's more Drilling and tapping involved because the slots don't allow easy ballscrew mounting. Drilling and tapping profile is a pain on thick walled stuff but this thin walled stuff is rubbish for tapping and holding threads.

I was thinking of drilling and tapping to a plate, and mounting off that to get the correct height.
