I got 5 BR blanks. I've never turned it and I know this stuff is endangered and rare so if there is anything I should know to prevent any problems I'd appriciate it excessive hardness? tendencies to crack or tear out? brittleness?
If so, while it is hard, it turns fairly easily but it is a bit chippy. A co-worker just put in a hardwood floor using this stuff and gave me a cutoff. I turned it the other day and put a CA/BLO finish on it today.
I treated it like PR, turned at 1800 RPM with a scary sharp skew.
Jatoba is Brazilian Cherry. Brazilian Rosewood is considered THE rosewood by many. It turns very similar to Honduran Rosewood - not quite as oily as cocobolo. Some people use cocobolo as a substitute for Brazilian Rosewood. Personally, I think cocobolo is prettier.
First, it is not endangered or rare. The Brazilian government put a ban on exporting for the next 50 years due to overharvesting of 'old growth' Brazilian rosewood.
It's not a great wood for pens as it tends to have a straight grain without much character. It's beautiful in larger objects, like guitars.
It turns like any other rosewood. I't hard, should turn very nicely, is a bit oily and takes a very high polish. I prefer to use lacquer over rosewood as a finish.
