I would have thought bolting the 9 cross pieces to the frame would be just as much hassle and a real pain to get them all in the same plane.

If you drill access holes on the underside of the top beam you will be able to use a T Bar allen key to bolt the extrusion directly to that quite easily.

Yeah i see your point, but its easyier than wedling it, warping it slightly then having to grind it off. once bolted its no hasstle to add a little tack weld that accessable for a grinder should i need it.

Good point on the hole on the underside of the beam!
