After hunting season I'd like to try my hand at making a glass recurve. I have some osage I cut and had sawn into 1" x 2" boards, mostly 84" long, two years ago. I was wondering what size of block do I need to start with for the riser? I was thinking of using the pattern from Bingham. I'd also like to go with a high contrast flare in the block and wonder what would be a good wood to contrast with the light brown osage ages to? I'm partial to cocobola myself but not sure what else would look good.
