For grinding core lams for a glass bow useing maple ,boo or whatever you want to use face grain (horizontal) and not edge grain (vertical) .......right or wrong? :confused:
Thanks for any help

Under glass it doesn't matter. My Treadway longbow has flat grain elm on the back and edge grain elm on the belly.
What Pat said, it doesn't matter under glass..
Which way on a wood bow????
In glass bows there isn't a lot of difference. However, I think I'd give a slight edge to the vertical grain.
I think edge grain or bias grain has better resistance properties for board bows but you also have to consider the grain along the sides of the board. A run off is a run off, no matter whether it is on the back or side.
This way on wood..

lowe s has bamboo that looks like the above wood on the end (solid bamboo vertical) You have to order it at the store to make sure you get the right one.
I have only cut one board so far
I got 4 lams out of it easy, might could get 6
I was taught to use quartersawn lams for the center for slightly better strength and consistency, and use flat grain under the clear glass for looks, and that's what I've always done.
