Interesting failure mode on my NewVaq...

Folks,

I was doing some work in the shop that involved grinding on copper pipe. I was also cleaning my gun nearby...far enough away from flying copper chips, or so I thought.

Heh. Not.

So I put my NewVaq357 back together, go to open the loading gate, it's stiff. WTF? Go to cock it as it's still unloaded. I can work the action but there's a weird "click" in the middle.

Odd. Take it apart, check everything, put it back together, same issue.

Whaaa?

Take it down yet again. This time I don't just pull the loading gate out, I pull the hammer/pawl/transfer bar assembly and scope 'em out in detail.

A chip of copper had gone down in between the frame and the transfer bar, way low, had gotten smashed flat in there against the transfer bar and was screwing with the transfer bar's ability to go up and down. It was sticking a bit off, not enough to render the gun a total doorstop, but the transfer bar was out of position just enough to block the loading gate from opening.

Huh!

Once cleaned up it was fine.

Lesson learned: at least in the mid-frames, the channel that the transfer bar rides up and down in is a damned tight thing and if anything gets in there, it can mean trouble. If you have any "hitch" in the action, check that channel in detail with all the action parts completely out.

The good news is, with the hammer fully down this area is pretty well protected from a failure of this sort, so I don't think the SA action is any more vulnerable to "junk dropping into the guts" than any other revolver type.
 
Thanks for the lesson Jim. Good point to remember. Bet you're glad you didn't have to send your "slightly modified" Vaquero in to Ruger for repair. :wink:
 
Heh. 'Zackly.

If it's not clear yet: I don't know if the clearances in this area are any looser in the large-frame guns. I suspect not - both take the same transfer bar, hammer and pawl so...the channels in the frame for those parts are likely similar if not identical.
 
What was really odd was, the copper shaving was smeared flat into what looked like a copper-colored stain on the transfer bar metal. It wouldn't have been very thick AT ALL yet it was enough to gunk up the mechanism.

Oh well. It was a good excuse to take a toothpick to every corner of the innards and just go to town on a detail clean...given that the gun was bought new in 2005 it wasn't that bad in there but you could almost eat off it now.
 
finish one job, and go on to another, it will never fail to happen, that 'something" will fly, jump, spill or fall over, onto, into or against anything adjacent, nearby, and cause havoc, yes, Uncle Murphy was an "optimist" in my mind...and the shirt says it all "S@#t Happens..."

same goes for using the same towels ( rags) to wipe something off, and I've seen guys wipe down a High grade shotgun, with a 'rag" that they just got done wiping "metal chips" off of a piece of 'other' work.......duh......
those are the the kind of folks we stay away from..................
