I drill the block in the piano, and haven't been able to picture = a=20 method of getting the varnish into the block without spending half a = day,=20 getting it all over the plate and bushings, or both.

Ron N My recent driving fluid experiment were on pieces of block = out of the piano and have yet to do it in the actual process. I've got = the messy thing too but from what friends have said is they swab a = couple rows of pins at a time, string ,swab more holes. It doesn't take = a flood of solution to make this work. You can even dip the pin in the = varnish, let it drip off then drive it in I would think. Probably easier = said than done but One other technique was to cut a slot in a hammer = shank and insert a piece of key bushing cloth wider than the shank but = smaller than the hole, dip it in the solution, then spin the device in = the hole. You know I bet Joe Garrett has some fancy fangled trick, he's = a neat freak guy ,right Joe? How about a hypo oiler. Put some drops = around the top of the hole then us! e something to swab So As I now understand it for a no. 2 pin fit in delignit, you bore = with drill sizes that are only a couple thous. different so the final = reaming isn't going to change the accuracy of the first hole drilled = it's just cleaning it up.
