Hi

I have a strut on a pram that has sheared. It's at a 'springy' point
but isn't particularly load bearing. The fracture hasn't caused any
distortion to the tube, and the two halves still mate nicely.

Main problem is that the fracture is just at the end of a curved
section, so making a suitable plug to tap into each end won't work.

In case it helps, the tube OD is about 22mm, with a wall thickness of
about 3mm.

TIA

A piece of tubing of a similar size with a slot cut along its length to form
a wrap round would probably do the job. Fitting jubilee clips (hose clips,
elephant clips) or drilling through each end and fixing with self tapper
screws or rivets might be a good way of holding it in place tighter.

Was going to suggest that - did it with a McClaren Buggy 20+years ago
using jubilee clips and it worked very well - in the end there were more
splints, jubilee clips and new wheels than I could count. The only
problems in your example seem to be the curve and the ability to flex,
although I cannot imagine how a plain 22mm tube could flex.

You could also just place strips of metal along two sides of the tube,
drilling through both metal and tube, and then fixing in place with self
tapper screws or rivets.
