If I am not replacing the block I usually ream with a #3 reamer and then install Low-Torque pins that are 3 ½ in the block portion. I prefer to ream as it gets to some new wood and often the tuning holes can be slightly burned when you extract the old pins.   You’ve received a couple of suggestion for going to 2 ½” pins as well as up a size and I think you need to be cautious about that unless you are reaming. If you don’t ream then the #3 (or larger) pin will extend deeper into the hole originally drilled for a #2 pin but was not reached and therefore expanded by the original pin. That can make the pin very tight at the bottom of the hole and can create some rendering problems. So, if going up in size in the original block I believe you should stick with the original length.   <div> David Love davidlovepianos@comcast.net www.davidlovepianos.com </div> -----Original Message----- From: pianotech-bounces@ptg.org [mailto:pianotech-bounces@ptg.org] On Behalf Of Paul Chick Sent: Tuesday, June 17, 2008 5:00 AM To: Pianotech@Ptg.Org Subject: Original pin block   I’m helping a person put his Steinway L together.  It has the original pin block that came with 2/0 pins.  The torque on all the pins was very consistent ( 100 “#), save the first three.  What size would you install?  Would you ream the original holes, and if so, what size drill/reamer would you use for example a 3/0 or a 4/0 tuning pin?  I put in a new block when I’m redoing a grand, but this one is nearly perfect and I didn’t want to replace it unnecessarily.
