Brazilian Rosewood
Might we see a pic of said Rosewood?
Brazilian is rather rare and some might like to be reminded of what it looks like.
As to the length, 24" I believe you said that you want to make 1pc butts.
If it's 24", it will have to be lengthened as most butt-sections are 29"+/-.
We have a board-stretcher that gets passed around for whenever someone needs it, as in your case.
I can't remember who had it last, maybe Brent, Rick, Joey, I forget.
