You’ve probably figured out everything about this post already, but I’ll go ahead and spell it out. I picked up a used scroll saw, for various purposes, but mainly for cutting bone blanks down to size for nuts. Gave it a quick try this afternoon and needless to say, didn’t work out very well. The blade picks up the material, so I was thinking about installing the blade upside down. Good idea or bad idea? And, should I use a spiral blade, or some other specialty blade? Bone is pretty hard stuff. Thanks!
