Advise for Black Walnut
« on: April 05, 2011, 03:00:27 pm »
Hello Everyone,
I'm new to bowmaking and need some advise on working Black Walnut.
From searching forums, I'm coming up with conflicting info. One of the comments was that the heartwood is weak in tension and that the sapwood is better. Is that the way this wood behaves?
I just got a 1/4 split log that has 3/4" of sapwood on it. How much sapwood should I leave on the back?
What style of bow works well with this wood? The length of the log is 62" and I'd like around 45#.
Any other things to watch for when working this?
Any advise would be welcome,
Thanks

WALNUT: black .55. Semi-ring-porous, easy to work, elastic for its mass, similar in performance to cherry, but more tension-safe. Will try to chrysal where cherry won’t. A wonderful, overlooked bowwood. Bows can be all sapwood or all heartwood, or mixed, sapwood taking a bit more set in compression. The off-white sapwood can be worked down to 25% or so of limb thickness, creating appealing contrast with the almost black belly. Very high heartwood extractive level, so as with similar woods, it may be more resistant to water absorption. It’s reported not to warp with rising and falling humidity, possibly for this reason.
WALNUT, European .56. Design as per Black. Not as pretty, but makes a nice bow. Strong enough in tension to tolerate being a “backward” bow: the crowned sapling surface as belly, the split back surface tillered.
hope this helps, onemississipp.googlepages.com, this will give you a list of bow woods and non bow woods and their characteristics, Bub
failure is an option, everyone fails, it's how you handle it that matters.

On the few walnut bows I made I used the wood under the bark for the bow. By doing it this way you might or might not get any heartwood in it and it will only be in the handle. I used Paul Comstock's overbuilt bow directions for my BW bows.

Well number 4 is usually the charm you will get be patient and take your time, also try to learn from your broken bows figure out why they broke or failed and make the changes next time if you can. Also if you can post picture here and people can help you and give you advise on tillering and design ect. Good luck
