Solving a 100-Year-Old Drill Chuck Issue

[HarrySTruman]

I have picked up a very old (possible 100 years of age), hand operated, bench drill. After cleaning years of dirt and rust off the machine it seems ready to go to work in the school workshop. There is a huge problem though, the drill bits will not centre in the three jaw chuck. I have had the chuck off and cleaned and oiled it. The three springs are present but I am wondering if they are worn. I know that it is possible to make your own springs with piano wire, and I have access to a lathe, but are there any other reasons why the drill will not centre? Also is there anywhere, preferably in the UK where I could get these small springs from if that is the reason why it won't centre?

Would be grateful for any thoughts on this.

Best wishes

Michael

Possibly made for bits that have a flat side.
