The main thing we are going to be doing this time is vacuum forming.  Here is a great instructable that outlines the process we will use:

http://www.instructables.com/id/Make-a-good,-cheap,-upgradeable-sheet-plastic-vacu/

A summary list of the items required:

? 1) Platen (board with a hole in it)

* 2) Pair of frames with clamps for holding plastic while heating

* 3) Stand for framed plastic in the oven

* 4) Oven

* 5) Vacuum

+ 6) Plastic sheets

+ 7) Molds

? 8) Window screen (placed under mold)

? Need it; * Got it; + Bring as much as you want

I have the oven and vacuum so please let us know if you can bring / make the other items in the comments below.  We'll only need one set of items 1-5, but plenty of plastic sheets and molds.  Anyone already have something they want to form?

P.S. If you've been to my house for a meeting before, you'll be happy to know that we've moved meetings out of the basement into the well lit and larger upstairs.

    It was interesting I have never seen it done before.

    For an oven stand to hold up the plastic frame I was thinking about something Houston designed for the electric chicken coup. The aluminum square tubing with holes drilled in one side and for aluminum rods. The aluminum square tubing would run horizontally across the oven grill and the rods would sit vertically to hold the frame. Sound good? If so, I can pick up rods and tubing. Am I making this more complicated than it needs to be? It doesn't have to be particularly strong... dowels in a 2x4 would probably work and make a more stable base. Any other ideas / preferences?

    A list of cool uses from the instructables site:

    1. intermediate molds for modifying and combining sculptural shapes (this allows you to sculpt in whatever medium is easiest, and transfer the shapes to plastic, making one copy or many)
    2. sturdy custom parts out of thick plastic to protect delicate machinery. (Using cheap homemade equipment, I've vacuum formed shells from 1/4" thick plastic that are sturdy enough to stand on.)
    3. three-dimensional, internally-illuminated signs from scintillating textured plastic
    4. flexible, cushiony custom liners from thermoformable foam
    5. relief sculptures of various kinds
    6. molds for casting chocolates, soaps, candles, or concrete relief sculptures
    7. decorative architectural reliefs, or decorative shells that can be reinforced for structural purposes
    8. stage props and costume parts in hard plastic or soft foam,
    9. zillions of things you'll probably think of.

    Found #2 particularly interesting: cases strong enough to stand on.

I'm surprised by the level of growth I've seen since becoming an organizer, it's given me more confidence in my abilities.
