I need to add a resonator to my banjo and have the '70s Stew Mac
mahogany resonator for it. I have built necks in the distant past but
never drilled into the rim or resonator myself.
I had a friend in those days who would cut and angled the necks for the one piece flange and he also
installed the resonator for me at the same time so never did learn to do this.

This is for a Top Tension Siminoff pot so I'm presuming that I'll remove a couple of bolts adjacent to the L bracket placements but any other things to do regarding TT pots?

I've repeatedly read that starting placement 3 holes from the neck and tailpiece gave Gibson
style ll" rims placement in equal quadrants but wondered what "tricks" there might be for
being certain that they will line up perfectly when adding the resonator receiving hardware.

I figured on just dropping the thumb screw into the L bracket, and using an awl to mark the
placement but not sure how to be certain that the receiving/hex hardware is the proper height
between the top rim of the resonator and the resonator's bottom.

I've looked at Roger Siminoff's google books page online but don't have his book yet. I can do basic set ups fine.
I think I can get things lined up on my own, but wanted to know what the proper, step by step
specifics/measuring process is. Any online links with video of the entire process out there anywhere?

I realize that this is SO simple after having built necks, but I really really only wanna measure twice/drill once ;-)

Thanks, NB

Measure twice, drill once.

I usually install the hardware to pot screw the pieces together then slide the Rez to position then mark with pencil then measure down and drill the hole with tape on bit so as not to drill through. I’ve never had this fail the tolerance is fairly forgiving
