I used to use a little jig with a fine saw-blade insert to mark a kerf each side of the tail and then plane up to here, but I do it by eye now and it's just as exact. >I am however not happy with my spacing consistency in general, >so....does anyone have some other way to prove verticality when >hanging hammers? I have a "three-legged" tray with a plate-glass mirror top. The angle can be varied in both planes. The left-to right slope is to accommodate the angle in the bass and tenor of Steinways etc. I'll try to get a picture of it tomorrow -- I know it's one of a number of things that has gone into hiding! Here are a couple of pictures I took to prove the concept before I covered the tray. JD -------------- next part -------------- An HTML attachment was scrubbed...
