Ralph Onesti sells a set of tools for installing new inserts, of any wood of your choice. I think lemon wood is a good choice because it is hard as well as lubricious. Ralph's tool set is about $400.00. One of the tools I hated to give up when I left Rutgers. The set consists of about 20 sized feeler pins, an insert cutter and a key cutter that holds the feeler pins. Very nice and accurate. Onesti is in the directory.
