Ive been reading this thread on locostbuilders http://www.locostbuilders.co.uk/viewthr ... tid=196041

and I have seen some of the failures used as examples on friends cars, not as bad but similar to the one below



My question is, why are the brackets welded to the top of the tube?

Wouldn't it be better to make the U shaped bracket with longer verticals so that you could slide it over the square section from below.

This would give a bracket that would take the vertical force and not the weld.

Just a thought.

I think you're right but it would depend on the chassis tube being in the right orientation to fit. From memory, most of the pick-up points are at 90deg to the chassis tube... of course you could have an over size bracket and a square hole through it and thread them onto the chassis tubes during assembly.

No i think that'll tear. as the hole would have a corner that would be the weak point.

Well I guess if you're going to the trouble you might as well do it right and radius the corner to match the tube... Not doing that would just be silly, obviously!
