I'm scraping binding on an old Gibson resonator that had lost much of its old cracked binding. Before finishing I wanted to find out whether the edges of the binding at the top, flange side and bottom or rear / back of the reso should be scraped and sanded to an angle or even a curve or should the top edge be flat- I'm guessing so and the back edge have a similar angle to the top of the binding as the curvature of the resonator back itself? It's a 28 tb2 resonator with two binding channels, the upper one being additional to my taste. As the resonator was in bad shape and needed a new veneer it's far from original. Thanks for looking.

It's been a while since I've had an old Gibson banjo in my lap, but yes, I would at least blunt the sharp corner so it doesn't hurt your arm or leg. If it were me, I would probably round it a little for comfort's sake.
Since it's no longer in original condition anyway, a minor liberty probably won't hurt the value, as long as the work is well done.
For the record, their guitars from the same period have a beveled top edge on the binding, with the sharp corner knocked off.

The edges are relieved a little. How much, I don't know.
The way I did it on the grand total of two resonators I finished was to roll a small piece of #320 or #400 sandpaper into a tube and go around the edge very lightly two or three times. Just enough to knock off the right angle. I'm pretty sure I read to do that somewhere. Not the type of thing I'd think up on my own.
I believe the edges of the peghead are also typically relieved or softened.
Answer is yes without question the edges are rolled, if you dont when you rfinish you will lern why its always done
Thank you Scott & guys, seemed most likely but best to check before regretting doing it another way. I'm using your finishing guide Scott which has a really clear sequence and explanation. Thank you for sharing this with our community.
