Before we go too too far down this road of beating up revolvers with babbitt bars, know that that's not what they were designed for. Babbitt is designed as a bearing material. About 100 years ago it was common for machine tools to be made with plain bearings made of babbitt. The bar part was just a convenient way to transport the babbitt to the tool. Where upon, the babbitt was melted into a built in mould surrounding the ferrous journal that needed support. It's a nearly dead skill set and I've hardly given it justice.
