Hi Hopper,
Countershaft pulley is 8" diameter and motor pulley is around 3".The motor has 1452 RPM stamped on it, so the countershaft should rotate around 500 RPM. In the centre pulley position the headstock shaft should therefore be about the same as the countershaft, eg. 500RPM. I have been looking for a 2" motor pulley which should be a better deal I think.
Re. digital tachos, I found one on UK Ebay for aound £8.00. Anyone know if they are any good ?
Mike.
