I don't know if this is complete, about 3" is size, one part is hinged but certainly not a knurling tool for the lathe, but could be wrong smiley

Thanks

Roger

If you had said a mechanics tool box, I might have suggested that the two on the right of the first pic were part of a tube flaring kit (as in brake pipes in common sizes).

The first 3 items are for cutting short screws and then dressing the ends square and clean.

That did cross my mind and might be right for the 2 on the left but haven't seen pipework in as large sizes as that though

Wouldn't they have have needed to have threads in them for that purpose though?

In a ribbon microphone a metallic ribbon is suspended between the poles of a permanent magnet. To give the ribbon compliance in the appropriate axis, it is usually corrugated.

The gizmo with the two gear wheels hinged together could be used to form suitable corrugations.

I believe that there was also a ribbon loudspeaker offered on the hi-fi market at one time.

Best regards,

Swarf, Mostly!

I've no sense of scale for No.2, but it looks like a punching or embossing tool, for a series of dents or holes along the middle of a strip of something.
Holes in watch straps maybe??

First pic looks like typical apprentice projects: stud clamps for holding threaded or non-threaded studs while end is filed or by the look of the hacksaw marks, screwdriver slot is cut in the end of the stud. No thread is needed to hold threaded studs in the split type clamps on the right.

Clamp is held in the vice while stud is filed or cut. Can be used to hold studs or punches while the end is shaped etc for special jobs.

The second two items in pic 1 are clockmakers' split stakes. Commercial ones are usually made of brass. The first one is probably for slotting screw heads.

I have a ribbon microphone but the corrugations are not as fine as Swarf, Mostly suggests.

Are the two on the right possibly for drawing down wires?

They are used for supporting clock parts while working on them. For example while staking new trundles into a lantern pinion.

Not necessarily specific to clock making, they are just a way of holding thin rods in a vice without damaging them.

True, I've found lots of other uses for mine when working on small parts.
