I think McMaster-Carr carries both chunks and tape.

Thanks, Tim. Good idea. I actually have quite a bit of it.
Unfortunately, the design didn't allow for it. Adding the space for a
bearing would cut into structural parts that I wasn't about to change.

I think the Slip Plate will work for this application (there is a slight
amount of play that will allow for the coating thickness), and I through
this conversation I have a good lead on Tech Line Coatings that someone
sent to me offline. I'll be using several of their products in my
engine installation.

This is by far the hardest lesson about freedom. It goes against
instinct, and morality, to just sit back and watch people make
mistakes. We want to help them, which means control them and their
decisions, but in doing so we actually hurt them (and ourselves)."
