I am making a glass laminated longbow. I have a chunk of bubinga wood that I think I can get two longbow risers from, but I am wondering if the grain angle will be an issue in the fades.
If I cut it in two, the grain will hit my fades at 60 deg. (looking at the end grain, the rings would come closer to being perpindicular to the fade tips). My original plan was to trim the board, and the end grain would have been a more horizontal 30 deg. Here's a photo:

It will be just fine.
Yep, doesn't matter.
You will be fine. Of course the strongest way is to have the flat grain on the sides. Looking at the end like in your pic the grain would be straight up and down. But being your fades are sandwiched between lams and glass you have no worries.
I always try to have my grain running as close to perpendicular to the fades as possible since that's what Jack Harrison said in his book...but given what others are stating, maybe it's not a critical as Jack describes.
Thanks Guys I am going to go for it.
I made this riser out of a 3/4" or 1" thick board and some glass, I think the grain (30degrees) was similar to what you have. no problems with fades, bow is a fine shooter (http://i596.photobucket.com/albums/tt46/Robertfishes/riserRC14b.jpg) (http://i596.photobucket.com/albums/tt46/Robertfishes/riserRC14a.jpg) (http://i596.photobucket.com/albums/tt46/Robertfishes/april2012bow2.jpg)
I got a killer deal on a shedua board, I have cut 2 risers out it..I used the piece on left on a build 3 years ago. You can see that the grain runs straight thru the fades on the last picture (http://i596.photobucket.com/albums/tt46/Robertfishes/2ndlongbowriserblock.jpg) (http://i596.photobucket.com/albums/tt46/Robertfishes/2sheduariserblocks2-1.jpg) (http://i596.photobucket.com/albums/tt46/Robertfishes/2ndlongbowriser4.jpg)
