My first pinblock and it's a Mason & Hamlin !!!!!

[FIXPIANOS@AOL.COM]

I'm ready to take on the challenge of installing my very first block. As luck 
would have it, it's a Mason & Hamlin "B". I need some questions answered from 
those of you who are in the know:

1. What's a forgiving block material for a first-timer? I've heard that a 
lower-ply maple block works best and am considering Bolduc.
2. I know that the Bolduc calls for a .250" bit. Does that sound right to 
those who have experience with the Bolduc?
3. Is removal of the old block going to be an operation similar to a 
Steinway? I've watched Steinway blocks being removed so have a basic 
knowledge of what to expect.
4. What is the approximate location of dowels for a "B" at either end and on 
the stretcher and how many should I expect?

Thanks PROFUSELY from an RPT with 28 years of experience who is looking 
forward to doing blocks. Any help is GREATLY appreciated.
