127T/135T gear

[rpwilson]

I've got a spare 127T/135T compound gear, as used for cutting imperial threads on metric 5" and 280 Denford lathes. Its brand new, never been used, only slight issue is that the teeth are cut to 14 1/2 degree PA, not 20 degree PA, because I couldn't source a set of 20PA cutters. To be honest, although the theory is that gears of the same DP but different PA shouldn't be run together, I haven't found that at the speed and loadings on a lathe leadscrew drive, that theres any problem.
Anybody interested?
