Have done quite a few myself. I use the stones from a Lansky knife sharpener. That way I can sort of "sneak up" on that perfect (to me) 2 1/2lb. crisp, clean, breaks like a glass rod, trigger break. After doing 10 or so, I ended up building a jig so I didn't have to keep re-installing them to check the weight. Finally saved up enough pennies though, and bought a used two-stage Kidd... and then another, and one more. That's the best trigger I've ever experienced...I have two 8oz/8oz, and one 12oz/12oz. They are dedicated Sage Rat guns, for sitting in one place and annihilating squeaks. I wouldn't pack a rifle with a trigger that light.
