Did you inside and outside faces?

all this belt changing is a pain..
Isn't it just !

I've been looking at the possibility of using a Scooter variator (CVT) but the standard 3:1 range doesn't seem enough to be worth while (My Hardinge manages to get 8:1 out of similar sized pulleys so I'm still investigating the idea).

BTW does your machine have a proper 'B' section stepped motor pulley?

Mine is fitted with an 'A' section which is eating the rear belt - I'll have to make a B section step pulley for the motor because they 'don't exist', according to every supplier I've spoken to! - I have some nice new fenner belting waiting to be fitted.
