In my next incarnation, the 4344, id love to keep away from mdf, its just not fun and to demanding. Pb is not with in
Reason, from my understanding, being the least dense,
1" pb was used in early cabinets at this size, so would a 3/4" mdf or bb equate to 1" pb. I have not seen or read other then maybe once or twice it it being used in place of 1" material.

I have to face glue my pieces my local wood distribution center has been closed. I can do 1/2(9ply)×2 or 3/4(13)+1/4(5) or 1/2+1/4 or 3/8(7ply)+1/2

Can anyone explain the density of pb vs bb vs mdf, and could I use a 3/4 mdf combination for the 4344.
