I thought you used a long brad point drill that did pierce the bottom of the block. So my question in terms of the ability for air to circulate is what's the difference between a small hole and a larger hole.

Except, I do not drill all the way through even with the "#2 drill"(??? what the heck is that???)! I don't allow any air from underneath. AND, I've found that the tops of the pins will be just fine, but the bottom will have rust on it. I suspect, (can't prove), that the lack of air circualtion in the cavity is somewhat the cause of this. Also, my studies have shown that the area of the Willamette Valley, (where I live, more or less), is an ideal mild climate that is consistant and favorable to/for pianos. That "wet" B.S. is put out by the Native Oregonians, (of which, I am NOT), just to keep the rest of the world from moving here!<G> In short, I think drilling all the way through is unnecessary in the process.

Anyway, I do seal the block, I do use a pin driving fluid which puts a light coating of varnish on the pin and inside the hole and even if you don't drill all the way through with the #2 drill you are poking a hole in the bottom that allows air to move in and out. If you want to avoid rust you have to move out of that rain soaked northwest where you live!

More often than not, they are rusty! Gee, I wonder why? Personally, I don't want ANY moisture getting into the pin block if I can avoid it. Hence, I do not drill all the way through. AND, I put a finish on the pin block...completely! In 37 years of doing it this way, I have had 0, (zero) failures, even on pianos that were subjected to extremely adverse conditions! So, there's the reason to NOT drill all the way through. Just another "fine point", like the Becket thingee!<G> Regards, Joe Joe Garrett, R.P.T.

Double drilling would make that possible and then the slight bit of wandering and run out as you line up the hole for the second pass would only impact the bottom of the hole and not the top. Drill the first pass from the top and then flip the block over and run the second pass from the bottom. Assumes, of course, that you don't drill the block in the piano after it's installed." David, That also assumes that a person would drill the pinblock ALL the way through.....Which I don't!<G> (with good reason, IMA) Regards, Joe Joe Garrett, R.P.T.
