I've been toolmaking and precision machining for 50yrs, my next door neighbour found these items while clearing out his fathers shed. He asked what they were used for, I have no idea, which leaves me unhappy to realise after more than half my life fitting, turning, milling and grinding, I know nothing lol Please help.

Just finished a varied 'toolmaking and precision machining' career due to the lockdown & I have never seen the item you show but I'm guessing some kind of custom hand de-burring or smoothing tool [possibly]. Any manufacturers name on it?

The bottom part looks like the long bolt with an odd head may fit inside it to expand the jaws to wedge it inside a pipe, except I cant see what it would push against to open the jaws.

Do you know if all of the parts are related? You could have more than one tool or gadget there.

I wonder if the plates and coil springs are part of a quick release mechanism or clip together assembly? If the plates were mounted the other way round in their holder, a spiked spigot would first open the plates but they would snap back under spring pressure and be held by the flat inner V
The other assemblies may be unrelated.

Can't see that working Dave as the two spiders that space the three plates out would stop anything being pushed up between them. Apart from that I don't know.

It is assembled with the head of the bolt fitting in the deep V so that when tightened it causes the 'jaws' to move outwards and grip inside a tube. The round assembly fits on the top so effectively it is mounted on a tube or wheel that can revolve it. There is s spring loaded arm with an inserted blade element that probably runs round the inside of another second tube. The slot in the plate allows it to move out to contact the tube perhaps under centripetal force or a missing spring.
I think it is part of a carpet making machine that is designed to cut off wool.

Perhaps it’s meant to expand into a tube , such as a bobbin , from a weaving machine , either in the weaving process , or the loading of yarn onto the bobbin ?
