I have long wanted to attempt traditional bow making. Today I took a step in that direction with some Hickory. My question is on the possibility for the wood that I have, I need to further split the logs that I have down and seal the ends. The main reason I am posting is to ask whether the heartwood can be used from Hickory. I believe that there is enough material from each quarter to make at least 2 staves, should I attempt to get a third by first removing the heartwood?
