Anyone know of a source for these woods in pieces large enough for a riser?
For the kingwood i would try www.rosewoodarchery.com (http://www.rosewoodarchery.com)
For snakewood several exotic wood suppliers have it but not much longer than 12" from what i've found.
Saw some bigger pieces on the big auction site.

Make sure the snakewood is "stabilized", which I believe means they impregnate it with epoxy or something to keep it from checking badly. They're kinda secretive about it.
