The frame gave me some grief. I posted elsewhere about it, but I noticed it had developed a torsional twist which meant that the tires would probably not all touch the ground.

In the end, I used my little Dewalt clamps to secure the frame, weighted to untwist the frame when I dipped it into hot water. It helped enough, though I could have used hotter water I suppose, just not brave enough to push it!

it is distressing to discover something like this at this stage, but thankfully still early enough to try and fix it
