I saw that tip about the tape somewhere else too. Can't remember if it was Myka or not. I will try that. The funny thing is that I got a single coil pickup cover from Stewmac as well(I know they don't make them). The single coil template is even too big for the pup cover - the screw holes don't have anything to bite into.
Is any type of tape preferred? I assume you don't want anything that will compress very much as you roll the bearing along it. I have duct tape, masking tape, electrical, scotch...oh, and some binding tape.
Drak, I agree the extra wiggle room is probably good, I re-measured and it is about a 1/8 inch extra all around the single (I really exaggerated when I said a 1/4 inch). Still - there would be very little for the pickup screws to bite into.
Thanks for the input guys.
