Hello everyone! First post here on the S&W forums. I stumbled on yall's FAQ and it is fantastic for the S&W revolver. I have a problem though with my Model 10 that I cannot figure out. I bought the gun cheap and bought it as a project, so I'd like to figure it out.
One of the cylinder chambers has a high spot in the gun causing it to seize when firing more than 30 or 40 rounds.
The cylinder-barrel gap goes from being approx 7 thou to 2 thou. There is no endshake. The timing on the revolver also tends to be a little bit slow (not terrible) on the one side of the cylinder.
Here's what I think it is NOT :
This is what puzzles me though... the cylinder face is ground within 1 thou, meaning that it is not uneven, so some other surface that the cylinder bears on IS. Getting this fixed by S&W will probably cost over 100 dollars, and that was never my goal in the beginning. I wanted to learn a bit more about revolvers.
What I'm asking is really what's wrong and what could I attempt to do? Access to machine tools is no issue, its really a mater of determining what's actually wrong.

Here's what I think it is NOT :
- A misaligned cylinder yoke. If this was the case, the high spot would not travel with the cylinder. The same would go for the timing of the revolver.
- A crooked or non-square barrel face. Again, just like above, the cylinder would be tight the whole time.
