This is a multi-part message in MIME format. ---------------------- multipart/alternative attachment Hi, I'm trying to improve my bridge notching. It's pretty good, but I'd = like it to be better. The problem I've been having is that it is very = easy to slightly round over the edge of the notch on the top of the = bridge with the back of the chisel. Any of you been there? =20 I've been using a standard Marples 5/8" chisel. I believe the bevel is = somewhere around 25 deg., but I don't have an exact angle. It does help = a lot if it's well sharpened. But is there more to it? Would it be = better to reshape the bevel side of the chisel (which I have down when = cutting out the top part of the notch) so that it's more of a rounded = shape, more like a scoop? Is there a special tool just for this = already? Just want to make em' as good as I can. :-) Also, more as a postscript, I had a problem with wandering drill bits = when I drill out the bridges. You may remember the thread. I tried = making my marks, and then using a sharp awl to mark them much deeper, = perhaps 1/8" into the cap in the direction the pin would go. That was = the ticket. The drill just followed those marks all the way. I just = finished up a set of bridges yesterday, and they turned out great. = Thanks to all for the suggestions on that one.
