Poured-in-place bronze bushes?

[Pete O]

As I progress through my tractor rebuild, thinking ahead to tasks that still need to be done, I have been contemplating how I might line-bore the bucket pivot holes for the front-end-loader. I'm too stingy (and the budget has already blown out too much) to pay someone to line-bore it. It occurred to me that I might be able to put a long shaft across the two arms and pour bronze bushes, similar to babbit bearings. I have in mind a setup and process that would make it possible, so that isn't my question; rather I'm wondering if this might produce an acceptable result, or is there some major drawback that I am not foreseeing?
