And for heat you just use a heat-gun?
My former is not nearly as nice. But I built it back in High School and have never seen fit to change it. Just a box and a few frames where I heat it over the stove top and drop it over the master with the household vacuum hooked up. Very un-professional but I have used it for about 35 years!
Very nice work Al and great to meet and learn from a renaissance man!
