SUPER CAT Stands
(Early Design Iterations)
To the left are pictures of some of the early
prototypes of the SUPER CAT stand. It was out of these iterations that the
idea of a "docking socket" evolved. Design notes are includes
I started with an idea from Bruce Strickling ("bstwo") about a making a base for the Super Cat using the bottom ½" or so of a second three ounce can fitted beneath the stove.
However, rather than making the union permanent, I cut a single slit in the sidewall of the lower can to enable the stove to be placed into or removed from the lower can at will, creating, in effect, a "docking socket" for the stove. Next, the docking socket needed to be anchored to something with a wider base than the stove to improve stability, especially on uneven ground. I created three iterations:
1. Base #1: First, I fastened the docking station to the bottom of a 5½ ounce pet food can using three aluminum pop rivets. The base of the the stove is now wider and the bottom edge of the new can holds better on uneven ground than just the stove itself. Better, but still not great. Weight for base #1: ½ oz.
2. Base #2: To build an even more stable base, I next cut a circle (4 3/8" diameter) from 1/8" thick masonite board. To it, I attached another docking station in the center, using three pop rivets. I then added three small (¾" long) brass machine screws near the edges of the masonite to create tripod legs for the platform. I used masonite, by the way, because of its relatively light weight and rigidity. This platform needs to be able to support the weight of a pot filled with up to a quart or so of water (approx 2+ lbs). Next, I "rubberized" the legs for better traction on rocks by coating them with a glue gun. Finally, I drilled nine 3/8" holes around the edge of the circle to remove unnecessary material in order to minimize the weight. Weight for base #2: 1½ oz. Though 1 oz heavier than base #1, it is far more stable.
3. Base #3: As a final trick, I used folding Primus canister stove legs, in conjunction with base #2 to create a super stable base #3. The masonite circle was deliberately cut to the same diameter of a the bottom of a Primus canister, which fits perfectly into the canister stand. Most people would probably not take this third step, but since I often carry the canister stand anyway, I decided to try it. Total weight for base #3: 2.2oz.
