Thanks for the wood info Justin. I usually use local wood here, juniper, serviceberry, chokecherry... I have had good luck with yew. That stuff is hard to break. The biggest enemy is central air in my house. The ac sucks the house pretty dry in the summer, but not too bad. The floor vent heater dries the already dry winter air to the point where all the bows that took a while to finish broke till I started paying attention to humidity in the air and moisture in the wood.
I have a question about just how low moisture can get in a normal looking stave. I have a cheap moisture meter and it had sometimes read 0%. It had read this in finished sinew backed juniper bows that shot without exploding. Is this possible or do I need to get a better meter?
