Single-Sixer
A friend brought over his single ten so I could install a set of Wolff Springs. He had mentioned slight binding to the cylinder while having the loading gate open. I noticed the same thing but didn't give it any thought at the time (figured some of the internals were rough). I disassembled it to polish any rough spots (1000 grit wet/dry) as I have done to all of my Blackhawk's. The pawl was in good shape on the top so the only thing I did to it was smooth the backside where the pawl plunger sits as it had a really rough surface there.
After reassembly, it will cock, but when I open the loading gate, the cylinder is bound up. After I get the cylinder lock lined up in a slot, I can close the gate and I can cock the hammer again. I've disassembled this thing a half dozen times and I still have the same issue. While disassembled, and the pawl plunger isn't in the hole, the cylinder will spin. I've looked at the pawl under a magnifying glass and there are't any burrs on it at all and the slot it rides in is smooth and clear of any burrs. I replaced the pawl plunger and spring in case that might have been a problem. The base pin doesn't have any roughness to it's surface. The ratchets on the back of the cylinder look good to my eye with no obvious burrs.
I notice where he had let the hammer/firing pin fall on the edge of a chamber, but there isn't any issues of putting a round in that chamber and no metal is displaced that might cause the problem I'm having.
The revolver is a few months old and has been shot a few hundred times. I've got 4 Blackhawk's of different calibers, and have changed springs in all of them and have smoothed all of their internals (to include installing free spin pawl in all of them). I have never messed with a Single Ten before and this issue has brought me to a stand still. I'm not an expert here, obviously, but I have never had an issue with disassembly, reassembly, and changing out parts.
