Where can I buy a new wheelbarrow wheel? Mine has a puncture. Seems mad
to
buy a new wheelbarrow but I can't be fagged to fix the puncture.

On my way to and from a Reunion in Scarborough the other weekend, I noticed
on the motorways, that the posts for the central barriers are held in he
ground with an expanded foam. Makes them easier to get out for repairs I
expect. My thought is, could a wheelbarrow wheel, be filled with this foam?
No more punctures :-))

If it is the same stuff used in lifeboats and other craft for both buoyancy
and noise deadening, it sets very firm, but can be worked with a knife or
saw. Just a thought :-))

Two problems, really: getting the foam into the tire, especially if
you want it evenly distributed (and you do); and as with all foams,
the cell walls break down under repeated loading, so it would go limp
and you wouldn't be able to do anything about it. There were "solid"
foam tires for children's bikes at one stage, and the ones we had
worked fine when new, but the tires eventually started breaking up
from the outside (I did the same thing to a shoe once, stamping on
small firewood instead of using the tomahawk -- der! -- I should have
realised that the lightweight cushiony sole must be some kind of
foam).

A few weeks ago I finally dumped an old barrow whose wheel had rusted
through. Blow me, but of course the next week when I visited the dump
again, there was a perfectly good barrow wheel in one of the skips!
