Lee Slikkers, I cut them with a chainsaw after I split a short block from the stump to verify that the grain was straight.
Easternarcher, it is paper birch......I will use them as self bows. I hate to use backings(personal bias and lazyness)
I find the straightest grain birch usually grows in a deep draw or sheltered north slope.......otherwise they tend to be twisted, and I can't tell if it's gonna be straight till I split it.......birch bark gives zero indication that I can see.
I have made birch bows 1 3/8 wide and less than 68 inches long with heat treated bellies that pull upwards of 70# @ 26 inches and with minimal set and no frets. I am looking to increase the draw length to 28 for the 100#er as that is about as far as I can draw a bow reasonably (I'm a half breed garden gnome/hobbit
) and then only if I get it close to my ear like the english archers do.
Gonna be a while before I get to it though, busy time of year for me.
