Cut a triangular piece of shrink-wrap long enough to wrap three times around your rod. The width of the base should extend slightly beyond the foot of the guide.
 Cut off the threads and foot of the broken guide with the razor.
 Select an appropriate-sized replacement.
 Tape the new guide to the rod blank.
 Wrap one foot with shrink-wrap.
 Heat with a hair dryer. You'll need electricity, so swing by a gas station or 24-hour mart. They'll usually let you plug into an outlet.
 Repeat on the second guide foot.
