The Jetboil Halfgen propane stove was used for the project. It's large 9" stove top has a 10,000 BTU burner that can boil a quart in a few minutes or be turned down to a lazy simmer.
My construction is not an exact copy, but it rhymes.
The stove is fully gimbled both athwartships and fore-to-aft.
6mm thrust bearings reduce friction between 9" and 10" stainless cake rings.

The 9" form factor is suitable for most pots and pans as well as an Omnia Stove Top Oven. The rods on the bottom were added to support counterweights as needed to prevent it from becoming top heavy.
