Restoring old uprights

Have been following all the tips on restringing old uprights that my original 
post a few days ago started.

Thanks to all who have offered many tips. It seems to me that the best way to 
go would be to remove the plate, bore the old pin holes to 3/8 and plug with 
3/8 hard rock maple dowels, or pin block material after adding a spot of 
epoxy or white glue for assurance.

My next question is, how does one bore the new pin holes at a 7 degree angle, 
which is SAP when boring a new grand plank? On a drill press it easy to do, 
but with an upright on its back using a hand drill that would seem to me to 
be almost impossible. Are there jigs to attach to a hand held drill that 
would facilitate this operation? Also is there a tool to make one's own maple 
or pin block material plugs? I'm 73 years old, and have not kept up with all 
the latest innovations in tools and technology, so please bear with me. One 
is never too old to learn!

Thanks once again to all who have contributed to this discussion.
