Re: Types of Mahogany?!?
Having cut a few thousand feet of Mahogany, I'll give my response
What was said about Philippine "Mahogany" is correct, it's not Mahogany at all. It has similar grain, in fact I've got a speaker cab made of it in plywood form, they call it "Luan".
Honduran Mahogany _on average_ weighs 3lbs a board foot, African Mahogany weighs 3.5lbs a board foot on average. That's fairly irrelevant, though, because Mahogany varies wildly. You'll know the weight of the wood if you're buying off a good online wood seller or from the Warmoth showcase. General rule: lighter is warmer, heaver is brighter.
Much of "Honduran" Mahogany (I use quotes, because it's usually just South American genuine Mahogany) being imported now, is poor quality. The old-growth stuff is excellent. The newer stuff is often very young growth wood.
The African Mahogany coming out now is generally very good quality. It can vary in weight and density from one end of a board to the other end, but is generally easy to find, affordable, looks good, sounds good, and is easy to work with. African Mahogany's color can vary from shades of brown to pink, almost like a piece of steak. Genuine South American Mahogany is usually the rust-color, sort of an orange-light brown-amber color like honey or maple syrup color (sorry for the food analogies, just trying to be descriptive).
Fuzzy grain is actually due to a board not being cut totally straight grain when it was originally milled. If the grain on the edges has a slight incline (like \\\\\\\\), then if can be fuzzy. Good fresh planer blades can normally smooth that out.
For consistency, weight, and tone, African Limba (Korina) is still king.
