First time build here, and I'm loving it. I'm about to install a set of Grover A-style tuners that I bought through Stewmac. I bought their drilling jig as well, because I'm sure there are going to be more mandolin projects in the future.
I've drilled all eight holes, no problem. The instructions with the drill jig describes the use of a stepped reamer for installing the bushings on the top side. However, Stewmac's instructions for the Grover tuners say to simply use a standard tapered reamer (which I have) to enlarge the holes for the bushings. My concern: with the shallow taper of the reamer and the required hole diameter for the bushing, that's going to also enlarge the entire hole going up to the tuner plate. It will be hidden, of course, but I'm surprised that Stewmac didn't use the opportunity to recommend one of their stepped reamers.
Any suggestions whether to carry on with the tapered reamer or stop and wait to get a stepped reamer first? I definitely want to do this by reaming. I've installed a katalox peghead overlay, and it would very likely splinter if I try to use a drill at this point.
Thanks
