20/6 Tool ID

[8ob]

Possibly one for the Lathists/Millists.

Came across two of these in the shed while digging out gear to go in the citric acid , does anyone recognise them or know their purpose in life ?

They look like tooling for a capstan lathe. Is the cylindrical bit 1" diameter?

I will put a stick of inches on them

[Hood]

Aye, that is what I would say as well.

 

[8ob]

Any use to anyone or shall I bin them

[Hood]

Suppose if you can find someone with a capstan lathe they may want them but probably unlikely they would as pretty antiquated.

What diameter are they? My capstans use 3/4" and 5/8" tools so might be interested. But they look like 1" or bigger which is for the huge Ward type capstans.

 

[Woody.v8]

You could mill a flat on them and use them as a boring bar.

1 1/2" OD.

Are they possibly to hold some sort of flypress tooling?
I'm thinking rubber/leather punching/shearing, perhaps with a replaceable blade?

Moving on.

A three morse collet chuck that looks like it works with a drawbar, is there a screw in tang available for these that would allow it to be used in the lathe?

Arc Euro sell screw in tangs.

Arc Euro sell screw in tangs.

See: https://www.arceurotrade.co.uk/Catalogue/Chucks/Drill-Chuck-Arbors/Screw-In-Tangs

Note only M12 and 3/8 BSW available for MT3.

The tang is only used for ejection, not for drive, so anything that screws into the thread on the chuck and is of a suitable reduced diameter (tang A/F of MT3 is 5/16", see http://www.tools-n-gizmos.com/specs/Tapers.html#MT) will do.
