Great. I knew it was doable for ya. I don't know what a smith would have charged you, but I would guess at least $50, plus down time in a shop too. Now you know why I have had to do all the fixing and slicking to my guns myself. Not only don't I have the money, but I like to do it myself and I don't like to ship my irons all over the place too.
I did send my Marlin 336 cowboy back to Marlin to have the chamber opened up and they got it back to me in two weeks, but I was nervous about it for the whole time it was gone. It was a warranty issue. There just are no cowboy type gunsmiths located around me.
You did good. Did you miss the ratchet sound when spinning the cylinders. I never seem to get used to the whiring noise, but they work as advertised. Great for reloads on the clock and poking empty casings out too.
