Osborne miter gauge. attached is a photo of some window casing I put in my daughters room today. The photo is of one of the corners I could post 3 others the same. I used my TS and osborne gauge and this is ONE cut set on 45% (WWII blade) no trim cuts no touchups and as you see I haven't even filled the nail holes or repaied the splitting from my help nailing them too close. (I'll post a finished pic. :P ) But when they say this gauge is dead on, man they mean it. I am just amazed how I lived with my stock miter gauge for so long. This is not a gloat but I love when something works as described.
