Today I went shopping and bought some South American mesquite (Argentina, I think). It's amazing how much color difference there is once you get it home and start cutting. Very much similar to the difference between African and Honduras mahogany. In fact, the texture of the SA mesquite is more mahogany-like than the Texas (honey) mesquite...and the grain seems to have more 'ribbon' figure, also like the mahogany(s).
So if anybody out there is interested (Mike Mastin?)...heads up. This isn't to say it's 'bad' wood...I just don't think it'll mix with the 'real' stuff.
I guess I'll have plenty of material for small tables that don;t go with anything.
