Jigs? I only use them for leather covered pads, otherwise I grind all my pads installed on the gun using a belt sander. Learned that way back in school and I have always gotten my best results with that method.
How do you protect the stock? Tape?
Yes, blue masking tape works well. Take it down to the tape, as close as you can without hitting the stock on the belt sander, then polish the remainder with emery cloth on a file, a hobby stick, etc., again using tape to protect the stock. Careful work and you get a nice clean fit.
