I am putting ss gf, ejector shroud, hammer and trigger on a NM BH .357. The existing hammer has scratches on the left side. You could call them gouges. I did a search and didn't find a post on this. Has anyone else encountered this, and if so, how did you solve it? I can think of 2 solutions, file the hammer channel down, or mill down the thickness of the hammer a coupla' k's. Any suggestions? This is the worst of my Blackhawks,,, they all have some degree of this. Don't want to put a stainless hammer on this just to have it gouged....

RoninPA has a very good suggestion. That is a very easy fix that I use on several of my revolvers. I use a lot of hammer and trigger shims when tune my revolvers up. I do not like any of the parts dragging on anything.
 
what Ron said , shim it and polish out the scratches, its the simplest, but not that hard to remedy the issue of the inside of the cylinder frame itself, thats what WE used to do, not a firm believer in the shims for all too many applications, more so with cylinders.:rolleyes:;)
 
I just ignore those scratches most of the time; KISS works for me.

Me too. Just part of 'using' BHs.
Sorry, guys, I'm just not cut out like that. I installed the SS hammer yesterday so I could get a msmt for the proper shims. The hammer now is scratched as bad as the original. Means contact with the side of the frame, in a major way. I'm going to start by honing the side of the hammer channel, must have some burrs in it, then I will check msmts again, work the scratches out of the hammer, install shims, and see if that takes care of the problem.

Me too, but the OP's are pretty deep and could possibly decelerate the hammer fall? Dunno but if mine were that bad, I think I'd take off the offending frame high spots.
 
no, you do NOT hone the side of the frame all the way down to the pivot pin hole, just the leading ,upper, inside edge of the offending side, works MOST of the time...in fact MOST of the time the scratches get there in the beginning of the use of the gun and once the burrs wear down or off, it stops, this happens all too often with stainless models as they tend to burr too easy and often in production...heck we've even seen off set holes through the hammer itself causing the tilt.....it don't take much:cool::rolleyes:;)
 
I wasn't going to hone to the pivot pin hole, just the upper portion. I have been warned about staying away from the pin hole. Guess I should have made myself a bit clearer. This revolver has had several hundred rounds put through it by me in the last 4 years, don't know how many the previous owner shot. It is still rough enough to scratch the hades out of the SS hammer I am putting in it. The gauges show .017 K of play. Maybe honing it down will increase this by a thou, but the burrs have got to go. Thinking about calling Ruger, see how much it would cost to have them do it, work out some scratches on the main frame & barrel, and re-blue the whole thing.
 
To avoid many "frivolous" warranty repair work many companies have resorted to a "it meets spec" reply and dump it back in the box to be returned.

To be fair to manufacturers, I've read on some forums where buyers scrutinized the INSIDE of an automatic and wanted a new gun because the machining wasn't up to their standards. Not that it didn't fit properly or function or was not sufficiently accurate they didn't approve of the machining done.
 
There were some high spots in the hammer channel as can be seen in the photos. This is after 3-5 minutes of working it down with a very fine 1/4" file. Already the hammer is working freer. will file the other side, then polish them down with a finger nail file. with final done with JB polish compound. I am thinking about have the frame/cylinder/barrel done with the Spartan Shield, depending on how my .45 lc grip frame comes back. I had a scope on this revolver using a Weaver style no drill mount, scratched the barrel on both sides, Scope is not going back on.
