You could use 1" re-bar cut into pieces inserted into the edges a covered filled over etc. Easy to find cheap too. It has raised ridges so the interference fit may be a bit easier to insert... maybe....
I ruled out rebar mainly because I have no way to cut it. As for the molten lead and wood? Guess I would test it first maybe on the inside rout. I don't expect it go up in flames right off, but if it starts to smolder, it could pose a problem.
