I'm redoing the drive in my lathe and the final belt drive is of the timing belt type, 1/2 pitch, 1-1/2 wide. Anyway I need to buy a new motor pulley and they are available three ways; plain bore, you bore and broach keyway to needed size, QD style where you buy a hub that fits the shaft and the pulley, and 'taper lock', pretty much like 'QD' but with different hub and pulley taper dimensions.
As the lathe is out of commission that makes the interchangeable hub styles look more attractive. Is there any particular advantage in favor of 'QD' or taper lock? I'm not particularly well versed in power transmission but it seems the 'QD' is somewhat more common and is a couple bucks cheaper than the taper lock style
Any opinions on this would be much appreciated
