I think it would be a possible wear point where the axle goes through the PVC but that would be load dependant.

👍 it is a concern particularly flexure as it is easy to squeeze the tube and deform the PVC so not a good idea to use standard 50mm PVC. However was back at Bunnings today getting some stuff for work and I had a look in the Plumbing section particularly for PVC which should stand up to the rigours of supporting the rollers and dome.
Found a 50mm Pressure PVC Solvent Weld Coupling which has 5.5mm thick walls so should be strong enough for the task at hand. I will make a Mk 2 version over the next night or so and see how it works.
Other alternative is aluminium tubing or some other method.
Cheers.
