Hey guys, I had a mahogany neck blank in my wood storage for years and always thought that some day I would make a LP junior doublecut-inspired guitar out of it. Yesterday I grabbed it from the basement and started working on it: I cut the scarf joint at the headstock. I know that Gibson doesn't do that, but I prefer it over the short grain. It's not going to be an exact copy anyway. When I was measuring out the neck on the blank I noticed that the tenon would only sit about 5cm/ 2 inches into the black limba body. I normally use longer tenons if I can. However, the neck blank is really nice mahogany and I don't want to scrap it. The joint will be hidden by a pickguard, so that might leave some room to reinforce it. Do y'all think that using mahogany splines (similar to the ones use in broken headstock repairs) could be a good substitute for a longer neck tenon? I made a little sketch, see below. Or do you think it will be strong enough with the 5 cm set neck?
