I just got off the phone with my local luthier. He recommended rubbing the endpin real fast, and the moisture in your hand and the friction will make the endpin swell slightly, and will create a much tighter fit in the hole. He was a little aghast that someone would actually stick a soldering iron in their end pin hole. He said if you stick a soldering iron in your end pin hole as recommened, it will swell up so fast you couldn't drive an end pin in that hole with a hammer.
