I have red oak board longbow #2 going. Have the measurements marked and the riser block glued on. I learned a lot from comments here, Sam Harper, and lots of great info on-line to make #2 a good shooting bow. I still have the pieces of longbow #1 to play with....backing, staining, etc.
After this one, I am going to scrounge for other hardwood pieces from contractors, lumber yards, wherever I can grab some hickory, etc.
Wish me skill and luck!
