Pipe Insulation

Making your own pipe insulation out of polystyrene can save both hot water and money.

This bench, specially designed to turn polystyrene sheets into pipe insulation, serves two purposes: It holds the soldering gun in place (with a wedge to allow for easy removal), and its channel guides the polystyrene past the gun's hot tip. Note the rubber band around the gun's trigger.
