Hexapod Pot Stand

Postby WanderingStovie » Thu Dec 25, 2014 8:42 pm

This is my hexapod stand. It evolved from the hinged stand with two "U"-shaped pieces. It folds flat. It can be assembled and disassembled without tools, to pack the pieces in a smaller rectangle.

I cut and bent six "J"-shaped legs from 1/16" diameter music wire. I inserted the short ends into a brass tube with an inside diameter of 3/16" (7/32" outside diameter and 0.014" thick wall). The wire and the tube came from K&S Engineering, and are sold in some hardware and hobby stores.

It's clever.....what type of stove will you use it with?

I have a 43.5 mm tall 38 mm diameter alcohol stove with a capillary strip around the inside, or I may use it with a CHS.

Nice......I like the fact that it has 6 points of support.

I calculated other combinations of tube and leg diameters for varying numbers of legs. The general formula for the inside diameter of the tube D is given in terms of the number of legs N and the diameter of the legs d.

D = d * (1 + 1 / sin (180 / N))

The K&S Engineering / K&S Precision Metals tubes have a 0.014 thick wall and outside diameters varying by 1/32". I computed the inside diameter for 3 sizes of brass tubes.

3/16 - 2 * 0.014 = 0.1595
7/32 - 2 * 0.014 = 0.19075
1/4 - 2 * 0.014 = 0.222

Some practical combinations are as follows, with the first three fitting inside a 7/32" tube and the last inside a 1/4" tube:

N = 4, d = 0.078, D = 0.1883
N = 6, d = 0.062, D = 0.186
N = 7, d = 0.055, D = 0.182

N = 5, d = 0.078, D = 0.2107

All your calculations paid off, you got the maximum legs in a nice size tube. :D

Will you put something on the ends of the wires to prevent sinking into the ground? Bicycle wheel spokes have little curved ends that might work if the wire is the same size to fit inside the tube.

I sent KSMetals an email asking prices and availability of 1/8" square steel (solid) for a project I'm working on. Thanks for the links ;)

I was thinking about round plastic feet, but have not looked for any yet.

Old rabbit ears TV antennas have nice round pieces at the ends to keep people from poking their eyes out. Maybe something like that would work.

A pair of needle nose pliers can curl some nice rounded ends. :idea:

Have you made or purchased a Capillary Hoop Stove? What is your thoughts on them?

I have made a bunch of stoves based on Tetkoba's Capillary Hoop Stove. They are easy to light, warm up quickly, and have a steady heat output until the fuel is nearly gone. They have inward jets that converge into a miniature tornado of flame, making them a good show and tell item on the trail. I like using them, but not making them.

I looked for plastic feet but did not find what I had in mind. It probably exists, but I do not know how to find it with a search engine. What I want would be shaped like a "T"-nut, but it would not be threaded, and it would be closed at one end. I suppose I could just use "T"-nuts with epoxy.

I could cut some round discs, drill holes in them, and solder them in place.
