I also agree with this philosophy,,,,, but I also add one
thing.
Burnish the holes with a 50-50 mixture of chalk and rosin. This IMHO will give
a better long term fit and control to the pin. The gun brush will clean the
hole of any burn and char that is in the hole and the objective MORE surface
contact area. ( Did you ever wonder why tuning pins are threaded?) To keep
them from being pulled out YES,,, BUT to give them MORE contact area for
friction. I would bet that the thread doubles the surface area (I dont know)
but to me , IMHO, it stands to reason
