If the gun is a proven shooter, I assume you're leaving the barrel and throats alone then?
I really like the long flute look, and Harton's chamfer is perfect. I would think cleaning up the machine marks in the flutes is some work if you do it by hand.

Now, for the sticky part. Ruger cylinders have a facet on the rear face. Every single one I have seen looks like it has been cut with a broken piece of glass. I always address this facet when I do somebodys sixgun, it just seems wrong to ignore it. This particular cylinder however had been dropped on a hard surface like concrete because it definitely bounced. It had TWO dents right at the juncture where the cylinder side meets the rear facet of the cylinder. It was just bent. So, what to do? How can it be made to look right? Well, the answer is by some visual trickery accomplished by some careful file work. What I am about to describe is what I call file bending. I first started with a needle file and filed out the machine marks on the rear facet. Then I progressed from a 220 tool maker stone to a 600 until I got that facet looking nice. That still left a dent on the side of the cylinder where the cylinder flat met the rear facet. So by draw filing with more pressure on the dent side and being careful to keep the radius little by little you can blend that dent into the curvature of the cylinder. Make no mistake, it is a flaw and it is there, but as you work the steel and go through your progression of grits you "ease" that transition a little more every time making it harder for even the most critical eye to locate. This is very simular to what I spoke of earlier about where sometimes for the good of a project you simply had to stop chasing that one pit in the steel and instead try to hide it by blending it into the grain. Here, take a look, again, very hard to take a picture of...

If the gun is a proven shooter, I assume you're leaving the barrel and throats alone then? NO, WE HAVE ALREADY CORRECTED THE THROATS. I AM GOING TO MEASURE THE BARREL FOR RESTRICTION AGAIN NOW THAT IT IS OFF THE SIXGUN. IF IT DOES NOT DISPLAY ANY RESTRICTION THAT IS A VERY STRONG INDICATOR THAT THE THREADS WILL NEED TO BE RELIEVED. ANOTHER THING IS THAT WE ARE WELDING ON THIS FRAME FOR SURE AND FOR CERTAIN. HOWEVER, THE WELDING WILL BE DONE IN INCREMENTS SO AS TO NOT AT ANY POINT INTRODUCE EXCESSIVE HEAT TO THIS UNIT. SO, IT IS EITHER GOING TO KEEP IT'S MOJO OR IT IS NOT. MY BET IS IT WILL BE SHOOTING BETTER THAN EVER ONCE ADJUSTMENTS ARE MADE THAT ARE PROVEN TO INCREASE ACCURACY. I really like the long flute look, and Harton's chamfer is perfect. I would think cleaning up the machine marks in the flutes is some work if you do it by hand. WELL SIR, TO BE HONEST, IT PRETTY MUCH BETTER BE AN HEIRLOOM BECAUSE THIS KIND OF RESCUE TOOK ME SEVERAL HOURS. IT CAN HOWEVER BE DONE AND I REMAIN AT YOUR SERVICE. STILL, IT IS ALWAYS BETTER TO BEGIN WITH SOMETHING WITH A LITTLE LESS UGLY ON IT!

Nice work, do you polish out the leads into the bolt stop notches as well. Love the BP chamfering.

The very last sentence in the quoted post says it all. This old crap I've seen perpetrated by various gun writers, kind of goes like this: I had this ole dog (insert your favorite brand and model here). I sent it to latest discovered hot shot by the author. The author goes on by blowing and going of what a great craftsman he/she is. Author goes on to state the "ole dog" had a bent barrel, no front sight, bulged chamber and you name the malady as a starting point with pictures. The author then goes on giving rave reviews of the resurrected dog, including it now shoots one hole groups at some distance with supporting pics. Guess what, the better than ever produced item didn't cost the author one cent. So for the rest of us it behooves us to start out with a fine example to begin with. It will be much more economical in the end.

Nice work, do you polish out the leads into the bolt stop notches as well. Love the BP chamfering. That's pretty hard to do. I know, I have tried to clean up the approaches. The cylinder can be set up on a machine and the approaches and the bolt notches can be recut or they can just be cleaned with a q tip and some blue remover. Re-cutting the notches and approaches will most likely require an oversize bolt. I will cross that bridge when I get to it.

Are you going to do the welding yourself Fermin? Mark, I am quoting you yet again since you asked in order to update you. I have been doing some TIG welding with a guy who clearly is one of the very best welders I have ever seen. His shop has more welders of different sizes and types than any shop I have ever seen short of a welding supply company. Between him, Alan and Ray, I would have to combine stupid and blind to screw this up. It would seem the benefit of finally having the correct glasses for what I need to see here are making a huge differences and I am confident I will have this narrow welding skill soon. I checked the barrel on the Dawg for restriction again while it was off the mainframe. There remains only a very slight amount as I can drop a pin gauge in the muzzle and while it does stop, tapping it VERY gently with a size smaller pin gauge will get it out the end. Examining the barrel under a good light does show some tool marks in the grooves so tomorrow I might tap a couple of slugs with some lapping compound on them through the barrel and see what happens. Maybe we can just "lap" the tool marks and the restriction right out.... I also checked the barrel threads on the frame threads and man were they tight. I very carefully started a tap into the frame to relieve the threads just a bit and backed it out and checked the barrel and it went it some smoother but then got very tight again. A little more with the tap and again checking the threads a couple more times until the barrel shoulder engaged the frame. I need to define what I did not want to happen. I didn't want to just run that tap into the frame threads because the possibility that the barrel might over turn from top dead center would require a bunch more work. Instead what I found was the shoulder of the barrel was contacting the frame way too soon and while it obviously could be turned back where it came from that would just be introducing all kinds of stress that didn't need to be there. So, I am going to have to install my freshly polished cylinder back into the frame and start the barrel in until it stops and have a look at A) how much end shake is present and B) what kind of cylinder gap is present. If I relieve the front of the frame or barrel shoulder the barrel cylinder gap will tighten and that might require some other changes be made. These would either be a built up gas ring or a bushed gas ring or taking a bit off the mouth of the barrel.

This is great work Fermin, thanks for sharing in such detail for all of us.

Speaking as someone who has worn glasses since the age if 5, glasses are only part if that equation. GOOD magnification and lots an lots of light are the others.
I'd like to see your whole shop one day.

I made a deal on a Miller TIG welder last night with all the necessaries. I will have it in hand before long. More to follow....

You come up with a name for your shop yet? Something along the lines of “Two Dogs Tawdry Tig Welding and File Bending”? Or maybe Fermin’s Famous Firearms Fixin’” would work too! Maybe “Neked No Neck Machining”! 😁

“Ferminator’s Phat File Restorations” Mission Statement: To boldly go where others fear to tread. Turning chicken shit into chicken salad served up on Ritz crackers with a side of Barranti leather. Can I get an AMEN?!
