My father spent the last few years writing a book on how to fix door
problems. It's currently only available in electronic PDF format, but can
be purchased and downloaded at the site http://www.doortrix.com , which
has sample pages and more info on the book.
We're still experimenting with the price and looking for ways to make the
purchase process more user friendly.
If anyone is interested in the book, please go to the web site and check
it out. I sincerely hope you enjoy.
