Need a piston for a 5 hp petter m, mine has a chunk missing out of the
These are no longer made, nobody has any new old stock, so if I can't
get one I will have to weigh the whole issue in!
That's a bugger - con rod collision? If no one on the groups comes up
trumps, you do regularly see bits of M at the sales (Enstone etc) or an
ad in SEM might produce. Don't even think about weighing it in for
scrap, as a last resort you'd probably recoup your outlay by breaking
W-e-l-l, I know I'll be shouted at by the real engineers here, but if you
really cannot run one to earth, you could consider using the piston again.
This is, of course, contingent upon the missing piece of skirt not breaking
into a port or its lack uncovering a port too early etc.As long as there is
sufficient piston to stop it trying to rotate sideways in the bore, filing
off the broken sharp edge will allow oil up the side without too much loss.
I'd certainly consider it if the circumstances were right.
It isn't as though it will be run every day or do heavy work & one WILL come
along in due course.
Others here would probably buy it as it is, but please don't consider
Good point - at least there are no inlet ports to worry about on the
'M'. My Bradford 'King of All' has a hairline crack in the skirt (again
looks like the result of sharp contact with a swinging con-rod while
dismantled) which has shown no sign of growing during the limited
running the engine has had in my ownership.
If all else fails just whittle a new one. A nice piece of ash would be best
and would last for years running for a few hours at shows.
I had a Series 2 Landrover for a few years and maybe 20,000 miles before
I stripped it for a head gasket leak and found a wooden piston.
Ash? Surely the densest (African) mahogany you can find. Also fit
an aluminium flame shield to the top surface. Dad and I had one in the
White and I think it was in there 20 years before we got it.
I quite fancy the idea of a stationary engine with a quick-release
head and a wooden piston, just to be able to show people! It might
even make that rusted-solid Lister D in the other shed worth sorting
In other news, I spent today walking up the banks of the Wye from
Chepstow. Now I want a steamboat! I've wanted one for ages, but if
you're in the UK and unless you live somewhere like Windermere or
Kielder, there's nowhere to run one. But the Wye looks nicer and
nicer, in those bits away from the roads.
