Back in the 1970s, when I got Falconwood pinblocks from Cliff Geers, it came with a booklet about installation. Originally he was the only supplier of this dense kind of pinblock in the US, if I recall. I do not know how the density of the Falconwood differs from the Delignit. They recommended using a .272" drill of the high helix variety. They also suggest speeds of 900 to 1000 r.p.m. I would also recommend buying a copy of the Piano Technicians Journal Reprints: Pinblocks and Plates and searching this list's archives for more ideas, there is plenty there!
