Pulley Clamp


1.) Drill a clearance hole for a #4-40 screw through both halves of the clamp.


*** DO NOT tap the hole you drill. The #4-40 screw must move freely through the hole you drill. ***

*** Do not drill the hole too close to the body of the clamp. ***

*** If you do the head of the clamping screw and nut will not fit! ***

2.) The center hole is cut by the Lasercamm and will clamp onto the metal shaft. DO NOT ream the hole. No actions should be needed.
