When attaching coupling, gear, or pulley hubs to the shafts of either the driving or driven equipment, a key is commonly used to engage two keyways (cut into both the shaft and the hub) to help prevent rotation on the shaft and to assist (to varying degrees) in the transmission of torque. From the end of the shaft, you could drill a hole with the centreline on the border between shaft and pulley and install a dowel pin in the hole. Or drill the same hole above and use a safe edged file to square up the corners for your key. A C Richards Knifemaker / Craftsman / Service Provider Joined Apr 14, 2006 Messages 3,815 Mar 5, 2010 #4.
