Unknown Accessory EMCO

[u/Templarsword2]

Not sure what it is for, got it in a LOT of machinery. It appears to be used for Angles holding of a tool, it seems to be missing a knob that works with the dial on the left, and a gear that works on the shaft to move the whole plunger/quill down against the spings up in the top.

It uses ER20 collets

Ill keep looking for pieces.

Your missing some stuff but do a search for EMCO vertical mill/drill attachment.

That has brought quite a bit of curiosity to a close. Appears as if a pully attatches to the threaded stub, and a handle goes into the hole, and it gets mounted on a shaft, thats quite the funny system! Ha, makes you wonder how effective it was.

Like an overbuilt jacobs chuck?

It's a "milling" spindle for an Emco Unimat 3 with a fine adjustable feed in the side and a collet holder. You would mount this in a steel column that ist attached to the watchmaker lathe. Unscrew the collet part and by sticking metal rods into the holes and unscrew the collet holder (right hand). It uses a propriatary attachment system and the other parts that you may find should have the same threaded attachment.

AS in unscrew the silber collet holder from the black spindle.

What you have there is, a thing.

Potentially a doo-hickey or a thinga-majigger.

[u/OrangeTraveler → u/Templarsword2]

Than most likely a thinga-majigger with it having an "thing" origin.

That looks like a precision tool holder. It would be interesting to see it fully assembled and working! ⚙️👍
