One of these links has a little more play then I like and I was considering repouring the babbit.
I see that a copper shim was babbitted in one of these two links. The other one may have had also had a copper shim and perhaps it wore off and fell away.
Is there a useful resource that explains the practical aspects of babbit work?
I can weld and solder, I have done a little brazing. I have watched videos of other people pouring babbit in much larger rotational bearings.
This website has at least 8 different babbit alloys available in small quantities, I'm not sure which alloy, or if any of them would work:

The other option I was thinking of is to buy some stock and try to machine a replacement link.
