The only use I’ve been aware of for the heat strips is in lieu of a heat box; they go on the press itself between the aluminum pressure strip and the formica. This method makes more sense to me than the heat box; direct, even heat across the bow’s surface. I got a heat controller that was kind of a pain to wire up, but the strips work great, even though I’ve had a couple of bonehead moments. I sliced into one of them on accident, and once the thermocouple slipped out cooking a bow at 330 degrees for about an hour until I caught it. Everything was fine except the bow. These seem to be the same quality as the ones I bought from Mike Fedora years ago. Lost those in a house fire. They weren’t on at the time, btw.
