Not a scene from War of the Worlds!

Though it does look almost alien!

Furnace shell is securely held by 3 pipe legs.

Shiny copper plate hardware...

The new leg attachment hardware looks expensive, but they are called "split ring clamps" and I bought them at the local home improvement store for less than $1.50 each. The thick copper plate gives them good corrosion resistance. They are held onto the Stainless Tube shell with 3/8-16 stainless steel bolts, a stainless washer and nut.

Hot legs... You make me sweat...

At $15 each, the legs as a total will probably be the most expensive "part" of the furnace.

But to be fair, they are the only component that has a multiple of 3 .. Actually every thing else is a single component.

But it is clear that without a solid base, all else is futile.

You can learn something everyday !

Despite using what I thought was adequately thick material for the legs, in reality they acted like giant springs> With heavy hand pressure I could make the tube bounce up and down by 4 inches.

It seemed crazy, but that' s what the geometry and material produced. I decided to go with 1/2 pipe fittings to try and get a good structural integrity... I think it will work!

Sketch of the design

Often I'll use 3D modeling to create a model.

Truespace and Alibre are 2 I use now.

Truespace is now free and Alibre can be purchased for as little as $99.

But since I'm traveling, it's sometimes hard to beat a good sketchbook and colorful highlighters!
