Jig Clamp ? and new Stumble Bee Jig I tied

[Cane Pole]

Firsty, I picked this jig clamp up at a yard sell. The shaft clamp screw is broken off, so I just used my pcb vice to hold the jig clamp. Works fine. I cleaned up all the rusty parts too.

My question is what is the round spring on the clamp for? It is rusty, so can I get a replacement or is it really needed?

This body, I first made a solid hot pink chenille then overlapped it with a fine black chenille. Better finish on the head this time too. I think. I don't have any head cement, so I just used some waterproof super glue.

This is jig number 2. Nothing to do today except wait for the Brady Bunch.
