I think you're right, steel is best. Problem is I have no transport other than the bike. Timber I can get cut easily and carry it in my fishing holdall, up to 1.8m or so. I'm starting to think this will be a temporary fix, maybe look to replace it with steel when the ply inevitably fails. just updated my post - keep it cheap and simple. Cut a length of wood in 2 pieces and strap it to your back.

I'll have plenty of pu sealant left when I've finished, is this any use to seal the edges?

Hindsight would be a fine thing! I bought the wood yesterday. There's a fella next to me who used to be a carpenter, he recommended ply over normal timber because the latter is as its weakest along the grain, this will what would come into play if the bike tyres rode against it.

you'd have to be bloody clumsy to break 22mm timber with a bike tyre, just keep the upstand to a minimum.

Kicking myself here, why didn't I think about trying to bend the steel channel it sits in.....would that be possible? It's 3mm steel 130 x 130 x 130. Is there a tool that might do this? 6mm each side would be enough.

there are 2 types of channel section. Rolled steel channel has sharp square corners (formed from molten metal to standard industry sizes), pressed steel channel has rounded corners (sheet metal bent into a U-section). The former cannot be bent, the latter could probably be bashed into shape with a lump hammer possibly assisted by a hydraulic jack but it wouldn't be a very tidy job when you had finished.
the good news is that the size you have quoted suggests it is the latter.

2 blocks of wood as long as channel, just less than half the width and several wedges. Hammer each wedge a bit at a time down the length. That will open it up if it's folded steel channel.

Pretty sure it's folded/ pressed steel. Anyway, job finished, bike now goes on without the tyres squealing. Not quite 100% though, I miss measured the front of the bike, the standard scaffold couplers have a profile that clashes with either the headlight, or the mudguard. Q clamps are the answer, they have a slimmer profile. Bit of a bugger really, I'm in Nantwich, closest supplier I can find is in Stoke on Trent.
