ROA with converter problem

[Jethro "Black Jack" Harris]

It's good steel, but it machines very easy.

And it did. My friend set it up on a lathe and I did the turning. Once around (~0.001) and it was still binding. Twice and the binding was pretty much gone. A little burnishing with fine sandpaper and it fit pretty well but was still hanging up in one spot. Turns out there was some deburring needed on the cap of the cylinder. I don't know the correct term for the holes that the hand goes into to turn the cylinder, but it was having trouble getting into one of them, apparently because of a burr. Was the burr there originally or did it result from the binding? I don't know. So, we smoothed that out with sandpaper and the cylinder turns properly. Except, in that same spot, if I cock all in one motion, it's fine, but if i half cock then try to full cock, it won't always go. Takes some manipulation to get it past that spot in that case. Pretty sure this isn't the result of anything we did. Is it possible the cap is just a little off on one of those holes? The other 5 cycle just fine.

Any thoughts?

I think you have just identified the chamber that stays empty.  As in hammer down on empty chamber.  Paint the nipple RED and don't load it.  Then, it's a problem you can live with.

Good luck,

Thanks, Dick, I was thinking along those same lines. But what I want to know is the why. Is it a manufacturing defect of the cylinder cap? Is it the wrong cap? I notice the cap is a different color than the cylinder. Is this normal? Cylinder is beautifully blued but the cap is more of a bronze.
