If you are not going to recap, then simply plane the top of the cap down to 
the string imprint depth, renotch to mid-pin line, put a couple drops of 
thin epoxy down bridge pin holes, dip new pin in epoxy and insert pin into 
hole. Clean up squeeze out with acetone.

You are not going to make any kind of super material out of a piece of maple 
by trying to "soak" glue or epoxy or whatever into it. Just epoxy the pin in 
place and you'll be fine.
