ChonkNC build progress: did some more fabrication. Planning to bolt the gantry legs to the base, but undecided how to attach the gantry to the legs; I'd like to be able to shim it for leveling (which suggests "not welding") but there's no obvious place to put bolts up there.

@emily Could weld some studs (threaded rod) on?

@yngmar Problem is the legs are vertical tubes, and the gantry sits on top of them, so there's nowhere to put a hole for the stud to go through because there is already a bigger hole there.

Might just cut some squares to weld over the tops, then studs coming out of the center of those.

@emily Oh, then you could go with that or tangs welded on. Or a flat bar welded to the legs to close them and double as tangs. That would increase stability too.

Tangs because then the bolts can be accessed better than with end plates.

@yngmar what do you mean by tangs?

@emily I mean like this. Strongest if you use a continous plate, assuming its going on the triangular part.

I might not have understood how it's supposed to go together :)
