im considering trying to make a bridge, ( or a few) from scratch. I know that many use quarter sawn hard maple, but I was wondering if other types of wood are acceptable. I might be able to get some Amish quarter sawn rock maple, but I also have a few large logs of black walnut from a tree I cut down I've been saving, possibly to make a banjo or at least the pot. I figure I might be able to take a couple slabs off the end with a chainsaw to get some quarter sawn pieces big enough for a bridge, and not really use up much of the log I'm saving for other projects. The wood has been air drying, not out in the weather but also not in a heated environment for a few years now. I know that in other types of instrument making, black walnut can be used for some of the same applications that more commonly use hard maple, like guitar necks and banjo pots. Any thoughts? Also fyi this is for a really cheap Engelhardt, I'm not a luthier, and I'd like to try this for fun.
