A few things of note from the wood data base concerning Santos Mahogany
Color/Appearance: There is a fair degree of color variation between boards of Santos Mahogany, ranging from a lighter golden brown to a darker purplish red or burgundy. The color tends to turn more red/purple with age. Quartersawn sections can show a striped or ribbon pattern.
Grain/Texture: Grain is usually interlocked, with a medium to fine texture. Good natural luster.
Endgrain: Diffuse-porous; medium pores in no specific arrangement; commonly in radial multiples of 2-3; reddish brown heartwood deposits common; growth rings usually indistinct, sometimes distinct due to discontinuous bands of marginal parenchyma; rays not visible without lens; parenchyma vasicentric and confluent.
Rot Resistance: Rated as very durable in regards to decay resistance, with mixed reports on susceptibility to insect attack.
Workability: Santos Mahogany has a noticeable blunting effect on cutting edges. Working characteristics are rated as fair to poor, on account of both its density and its interlocked grain. Staining or
gluing can sometimes be problematic, though the wood finishes well.
Odor: Santos Mahogany has a very distinctive spicy scent when being worked. Trees from the
Myroxylon genus are used to make Balsam of Peru, an ingredient used in perfumes.
Allergies/Toxicity: Although severe reactions are quite uncommon, Santos Mahogany has been reported to cause skin and respiratory irritation. See the articles
Wood Allergies and Toxicity and
Wood Dust Safety for more information.
Highlights: Interlocked grain, severe blunting effect on cutting tools, distinct spicy perfume when worked that is know to cause respiratory problems (seen that one first hand), gluing is problematic. No, not the board you want to saw in half and reglue (because its likely to spring like heck fight you all the way), and definitely not the place to start practicing hand tools. Great floor or counter top in your bath room though!
I can remember one day in the flooring department of the millwork shop I was at for years they were running Santos in one room and Cumaru in the other. Cumaru has a distinct smell like horse manure when milled, santos wreaks like strong perfume. One of the younger helpers was walking from room to room cleaning up and commented "Man, one room smells like a French whore and the other room smells like a french horse...." Hysterical and accurate! Enjoy that stuff!
