This one has me puzzled. It was in one of the boxes of change gears and/or tooling that came with my lathe.

Reminds me of a hypodermic needle, but on an alarming scale.

It looks like a tool for inserting pins in mil spec connectors. You solder the wire into the pin then the wire sits in the groove and the end pushes on the cup of the pin.

What is this used for? I've never seen a reducing sleeve like this before.

Description says: MT Spring Grip Emergency Sleeve.

I've never seen one of those, but... I can see how it'd grip a damaged morse taper, the direction of the spiral means it would tighten up under load and the tang would stop it rotating in e.g. a tailstock?

I have never seen or even heard of one

Good idea it would get really tight , but still release better.

Here are 2 examples of a rarely seen tool. Who can say how they would set one up & use it? I have them & know what they are, but......I really am a NEWB.

Looks like a diamond radius dresser for a tool and cutter grinder.

Correct kd4gij! Hoping some can say how they would set one up & use it? I see a big grinder in my future.
