"Looking very nice ad sturdy.

This is how I got my beams sorted I welded 15mm plates on each end and then had them machined parallel and to length. I also had two faces of the box machined to get the box section true so that the front plate could be bolted to the beams true"


How did you do it Clive? Asking as this should be done in one operation/clamping - long piece.
Thanks

They were done on a Hurco VMC clamped and machined in one operation ie front and top faces machined and both ends. But I had to take the two beams to a guy with a horizontal mill to get the holes in the ends drilled and tapped.

Then the front gantry plate was bolted to the machined faces of the 60x60x5 box.
It was the only way I could make sure that the gantry would be square and true.

The drilling at tapping cost me about £25 for the 16 holes.
