IVe “successfully” set and sharpened a handful of saws, far from perfect, but good enough for me. These have been larger saws, 5-8 tpi, which I suppose are a bit easier than fine saws. One of which was a 12Inch Disston back saw, I filed to rip - was in very bad shape, and it still is, but it cuts adequately. Recently I decided Id finally get around to a beautiful split nut 14inch brass backed saw I bought years ago and have never touched. It’s 11-12 tpi and Im filing it for crosscut. The teeth were all different sizes, no set, and dull. So I first jointed, taking passes with a mill file until 90+% teeth had been contacted. Then I went straight to setting, then filing. Long story short, I messed up. It cuts, but is dull. The teeth look a mess. I realize now that I should have, after jointing, re-defined the teeth by filing with no fleam - then setting - then filing fleam. Im wondering if Im using the right size file because it seems to be a little more aggressive than Id like. Im using a double extra slim 6Inch bahco. And I want to verify something - I read once that when the file is placed in the gullet, the tooth should measure slightly less than half the width of the file. Part of me wants to sent it off for a professional because its such a beautiful saw. But the other part of me is stubborn and determined to learn this better. Any thoughts would be appreciated.
