I took a long aluminum rod tube and wrapped it with the heating elements from an electric heating pad and wrapped that with some fiberglass insulation. It maintains an internal temperature of about 150 degrees F. It hangs above the workbench and keep strips dry in the summertime. It also dries soaked strips in just a couple of hours.
