Re: Sourcing approriate lumber for strip ceiling
Sapele is cheap, available, and absolutely beautiful. Not bad to work with and has a pleasant but light scent.
Sorta like cedar with a tiny hint of oak. A soft scent. Ahhhhh...
It compares quite closely with Honduras Mahogany in rot and insect resistance, but is slightly stronger (and very slightly heavier), and much harder.
I've found it to be relatively forgiving of bending to easy large radii (such as a hull liner) when its hardness is considered (harder than maple actually), but suggest you stick to nice, long, straight grained planks if that is your use.
Afromosia is nice stuff, too. Half the price of Teak, but twice the cost of Sapele.
Iroko would be an excellent compromise as well. Its price falls between that of Afromosia and Sapele.
