Jacobs chuck key

[charlieboy]

Just bought an old lathe with a No 32 Jacobs chuck (1MT, 0-3/8", 1/4" pilot hole), but no key. Does anyone know which key I need. I think it may be either K32 (10 teeth) or K2 (11 teeth), but I'm not sure which.

I had this problem once with a drill chuck key, I ended up taking the chuck into a shop selling chucks keys and after a minute or two found the one I needed, so perhaps try that - saves guesswork.+

Thanks guys. I'll try the K32, as advised by Phil.
