Hi, I was at a class, recently, where Andre Bolduc, replaced a pinblock in a Steinway. He did it in 3 hrs, and it included drilling the tuning pin holes. Previously, I had just used a centre punch, and dimpled the location for the drilling of the pinblock holes. He said use drill bit that just fits in the plate hole, and just start it, and remove. Then when you remove the block, to drill at the drill press with the proper size bit for the pins, there is no wandering, as the V dimple fits the profile of the drill tip. I think I got his explanation right, and I hope it would solve the problem of keeping the drill at the exact position you want it. Regards, John M.
