The message from Steve Blackmore contains these words:
The TAIG motor pulley is presently 1/2'' but i cant bore it out to
5/8'' without losing the smallest pulley diameter, what I need is a pair of replacement pulleys one at 5/8'' and one at 1/2'' so i can use the motor with the 5/8'' shaft, it is a high quality GEC motor, brand new and unused running at 2850 rpm so would be perfect for my needs,regards, Terry
