I went down to Antifriction yesterday afternoon. They gave me a coffee and were very friendly and helpful - but didn't have what I wanted. I was there the best part of an hour whilst the young fellow pored over his three day old catalogue, ably assisted by his mate and their boss.
Eventually, they appeared with a solid steel pulley that would act as a pretty good flywheel on a bigger engine than the one I'm working on! It cost £17.00 odd, plus another tenner for the tapered fitting in the centre that they'd have to order - and the boss was far too big for the application I'm endeavouring to complete.
So I thought I'd try this Fount of Knowledge ;o))
