• The arrow was supposed to be pointing to the airgap between the two bits of extrusion where all the load will be transferred through two thin plates. I lack paint skills.

    You want the bits of extrusion to clamp to each other face to face not cantilevered up on thin plates.

    Re:price
    You don't need S355, fixtures need stiffness not strength. Better steel gets you a better yield strength but the stiffness will be the same.

    That price will go down if you add more bits. Small orders are priced WAAY higher to account for set up and office time.

    But then it can't rotate? Am I missing something very obvious? The angle of that beam needs to be adjustable.

    I could do 3mm CR4 instead but it saves 5 quid on the entire order so figured I'd go for 4mm.

    This line of thinking had me painting 50 bookends a while ago. And deburring a lot of clamps because I forgot to tick the box. With the company I use here 1 piece tends to be about as expensive as 5 and then 25 is about double the price of 1.
