Black Powder Chamfer Advice

[Aquarik]

I am considering adding a "Black Powder Chamfer" to a Model 36 as part of a restore & refinishing project. I've always liked the look on larger guns. The thing that concerns me is that the thickness of the material at end of the little J-Frame's cylinder and each of the charge holes is mighty thin. I'm worried that the chamfer will change the relationship of the cylinder gap, and could cause the gun to spit lead, or even worse crack or rupture the cylinder wall. I'm leaning towards not doing it, but would like to hear what others have to say. Any thoughts or experience would be much appreciated. Thanks in advance.

I don't think I have ever heard of a BP chamfer. What is it and why would it be done?

It is like the bevelled edge at the front of a Mountain Gun cylinder. I believe that it is supposed to aid in holstering.

Instead of a full chamfer, you could just bevel there corners of the flutes at the leading edge, like some of the older Smiths. My pre-27 has it and it looks good.

The only way I have ever seen it done the chamfer in no way compromises strength or barrel-cylinder gap. It's simply a slight radius on the front edge of the cylinder.
