What ist? - Vinny - 21-06-2021 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!) 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. RE: What ist? - Spec - 21-06-2021 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 RE: What ist? - Veggie - 21-06-2021 Its for winding the town hall clock. RE: What ist? - PyreneesPlot - 21-06-2021 MrPP wonders if it's a bevelled pinion for turning a cog, from a mill or press perhaps?

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 RE: What ist? - Veggie - 21-06-2021 How big was your bedroom, Spec? RE: What ist? - Small chilli - 21-06-2021 No idea. I showed Bob he doesn’t know either. It’s a very interesting lump . RE: What ist? - PyreneesPlot - 21-06-2021 He says they're twisted because it works at 90 degrees, connected to the bevelled gearbox, or something. Or maybe a spiral bevel gear, he's just said (he's been googling all evening, liking an engineering conundrum).

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. Where's Fred Dibner when you need him? |
