Matt writes “My short how-to on making a doorstop form pvc pipe. I like to think of pvc pipe as the modern day erector set….an old house and the inherent settling which may and does occur; our floors and doorframes aren’t exactly level or square. This being the case my office door has a tendency of closing on its own ever so slowly. While I have done my best at making adjustments to the hinge locations it still wants to close. Now I could buy a doorstop at my local home improvement mega-store but what would be the fun in that? Hence my homemade pvc doorstop.” Link.
