Re: 1" Bore Timing Pulleys

We use HTD5 all AL pulleys and then bore them out on the lathe. Plastic pulleys we have found do not have the clearance to drill out with a key way. We found it better to drill in several steps from 1/2" to 1". Our HTD pulley supplier got out of the business and we are looking for a new supplier. Lead time can be a problem.
