Brought a piston into work

[Ikemi]

I have a piston from a C63 AMG knocking about ... Not sure if I'd use it as a coaster though? I feel people at work might think I'm a little odd having it on my desk.

Bloke I had regrind the valve ports on my bike had a valve sitting on his windowsill that apparently came from a diesel backup generator. It must have been nearly 2' long with probably a 2" diameter head.

You mean something like this:




Base diameter is 4" (100 mm). Exhaust valve from a Stork Werkspoor diesel engine

Have some internet brownie points! It is a small jet engine, bit archaic by more modern turbine engine standards but still runs perfectly.

Cool, have you used it to actually propel something, or is it just for principal demonstration purposes?

If you havent, go check out Colin Furze on youtube

Colin could be considered as unhinged, but his vids are fab to watch

Here's my paperweight, from a Velocette Thruxton motorcycle.

Looks really lightweight!

I had a piston from an old V4 Transit which I polished up to look like a mirror on a lathe , then I cut it down on the second piston ring groove .

I gave it to my old man to act as a paper weight in his home study about 40 years ago , we were going through his things recently and we couldn't find it .

Worth bugger all I know but I'd love to find the damn thing.

6 posts in five years, I fear he lacks practice at posting pictures.

My computer desk paperweight (it's on a stack of proper papers now, pic taken just after cleaning) reminds me, no matter how good they look, not to buy another Alfa

Interesting topic, I'll post up a picture of a valve tomorrow that I've had with me for around 20 years, it sits on my desk at work.

Out of curiosity, what engine is that from, and what was the failure mode?

2 litre twinspark.

Failure mode was exit block front at about 70mph on a DCway

Or, as no-one troubled to warn me before hand, seems the exhaust on these runs down the front of the engine and backwards through a recess in the sump, putting the hot exhaust just under big end #3. So if the car has ever been run on cheap oil, or run low (not by me in either case, I'd like to point out, I only had it a few weeks!), the oil in #3 gets cooked out...

There was certainly oil in it .2 secs beforehand, a very impressive cloud behind me.
Oh, also turns out to be an effective, albeit expensive, way of getting that Audi tailgater off your arse

I've got a pistol from a top fuel dragster - that one piston produces more power than a Veyron [for 4 seconds]

I have this piston from an ammonia refrigeration compressor, that I rebuilt many moons ago in the garage. Commonly used as a door stop. Ooops image on its side.

I should have swiped the Volvo D13 and Mercedes OM471 Euro 6 pistons from the workshop when we went bust. Both 13 litre engines.

Both have a good weight to them. Made of some extremely tough steel. I can see why the Volvo was able to survive some very serious knock (probably detonation really) when running on natural gas. I had cylinder pressure traces that spiked off the chart (300 bar!) And it made the whole truck buck violently on the rollers!

Somewhere, I have a piston from Nelson Piquet's 1981, Argentine GP winning Cosworth. Damned if I know where it is though.

Was yours fitted to the engine when it won the GP?

I've got one as well, but mine is from DFV 269.

I've currently got a piston from a Rolls Royce Griffon sat on my desk, successor to the Merlin it came out of a Shackleton AEW plane

That small, recessed sump was a bad move by Alfa. Even worse when you see the size of the sump on the Nord engine. 6.5 litres of finned aluminium goodness:
