Car boot sale yesterday,looking at this lump of metal on a stall but wanted two cold chisels she had for sale. A squid for the pair of cold chisels and storeholder threw in the 'lump' for nowt. (Not at me!) Smile

Any ideas? About five inches long with a large twisted cross on one end and a smaller twisted cross on tuther. A large nut in between.

She thought it may be a bleed key for an old cast iron radiator? If it is I can't find a similar one on goggle.

Excuse piccies as my phone is pretty carp.

Vinny could it be a key to tighten the insert for the valve locking nut? not sure the correct name for the insert, but I think the tool resembles the type of key that's used for that radiator fitting

MrPP wonders if it's a bevelled pinion for turning a cog, from a mill or press perhaps?

I can't understand why it is, or needs to be twisted at each end though? I don't think a pin engagement could do that, not without heat so I assume it was manufactured twisted?

Doubtful the town clock that I had in my bedroom used a thing like a starter handle

He says they're twisted because it works at 90 degrees, connected to the bevelled gearbox, or something. Huh Or maybe a spiral bevel gear, he's just said (he's been googling all evening, liking an engineering conundrum).

Likewise PP! Rolleyes Just it bugs the excrement out of me when I can't find anything similar.I understand the principle of a crown wheel, pinion and planet gears but can't figure how this would equate?

I still fancy its a double ended key for something that needs a spanner on the large central nut to turn it, but still can't understand the twist? I don't think its been forged, more likely to be a cast steel lump methinks.
