I have a lot of small wild plum saplings where I live, up to 6" across, but I have not had as much luck as I like with them, because a LOT of them, almost all I have tried, have really twisted grain, like it can't be split and turns 60-90 deg over, say 4'. I have finished MORE knotty little plumb self bows than anything from them, bcasue a ton of knots seems to change the way they grow.
With a backing, do ya suppose I could saw out a blank from hearwood and ignore this twist? like grain angle might approach 5 degrees, Works with some selfbows...
