[pianotech] Bottom Board Material

[Delwin D Fandrich]

But it does hold screws well. It is, after all, made of birch through and
through. As such is it is not particularly cheap though I wouldn't call it
frightfully expensive either. Yes, it is consistently flat. It machines well
though you can pick up nasty slivers if you're not careful. It has been used
by many manufacturers for making jigs and templates that have to last a
reasonable amount of time and remain stable and accurate during that time.

So if it is not screw holding ability that makes you favor Baltic Birch
plywood, what is it? I know you have written about it numerous times in the
past that it is your choice for jigs and other applications. Cheap?
Consistently flat? Easy to machine?

Thanks.
