I made this at Techshop
1x2" pine wood. i bought 12 8ft sections. I have extra. but i did screw up some.
Nail gun with brads
Screen from abandon starwars bike. (Note If you don't have a abandon Tie Fighter starwars bike then maybe your loud neighbors don't need their screens. No screen = bugs. Bugs = closed windows. Last resort is to buy some.)
Staple gun with staples
Pocket hole jig with bits
A base board would have a hole in it for a household vacuum hose. A small frame would be built in the center of that measuring 11in x 11in. It would be glued to the base and then later sealed with caulk. A square section of pegboard would be glued to the top of that frame and act as the bed for the vacuum former. Separately, two frames made of MDF would sandwich the material to be vacuum formed and those would be held together with bolts. Some sort of rubber tape would run around the perimeter of the frame to form a vacuum seal. This frame with the material in it would go into the oven to heat the plastic and then be placed over the bed to form the part.
I bought the following parts from Home Depot for this project: 1x2-8ft Strip: $0.98 White Peg Board Panel: $8.45 3/8"-16 Wingnut (3 bags): $3.54 Hex Bolt, 3/8x2-1/2 (8x): $2.96 Foam Tape: $5.67 1/2" 2'x4' MDF Project Panel: $9.73 The following are extra parts that I used to make the table a little more user friendly and had lying around: 1x4-8ft Common Board: $4.12 3/4 PVC Pipe: $1.23 3/4 90º PVC Elbow: ~$1 The total cost before tax of this vacuum form system is about $38.
You'll need basic wood working tools for this one: a miter saw, circular saw, and a power drill. Wood glue is a must and caulking is optional but recommended. I found a Dremel was just fine to do the job of cutting the center out of the frames, but any method you prefer will work too. You may also want some type of square to make sure those corners are 90 degrees.

After the first few years of growing in these, we realized that not bending down was not only comfortable, it made weeding enjoyable! This made fewer weeds, which meant bigger plants. Because of this, it's very useful for those who don't want to bend down to weed but still like to grow a garden, like your parents or grandparents. Although our first gardens were made from tractor tires, we had a few semi truck tires around too. These turned out to be movable with the fork lift, and therefore pretty handy to give away as presents (yes we asked first). We filled the bottom 2/3 with mulch created as waste from a pallet recycler, filled the top with locally produced compost, and wrapped a "skin" on the outside made from off-cuts of the hardwood and lumber industries. When we found out that one of the world's largest tire dumps which is visible from space, was about an hour from us, it occurred to us that we could perhaps call these neat little gardens "99% repurposed materials"!Materials:
Tires, any size but each tire must be within 1" of the tires on either side of it in the stack(I'll explain later)
Tractor tires: 75" and up
Semi tires: ~36"
Car tires: ~18" (good for replacing those rotten whiskey barrels in your front yard!)
2" stainless screws
Mulch for the bottom 2/3 of each stack (your city probably sells it from trimming operations)
NOTE: If you're making tractor tire gardens, they don't have the support to use mulch in the bottom. Take up some space with a few short logs, and see if you can find "fill dirt" which is cheaper than topsoil
Planting soil for the top of the stack (local compost is great)
Skin material, which can be:
Paint, look for old 1/2 cans at a hazardous materials redirection sites
Wood scraps, such as: crown cuts from sawmills, straight liner cut offs from hardwood processing, old fence boards, or pallets (if you're desperate, they're hard to disassemble)
Seeds or plants
If you're using wood scraps, you'll need a way to attach them. We have a pallet bander, which works beautifully, and that's a great option if you can borrow it from your shipping department. Black ratchet straps will work plenty fine, although the buckle might be in the way. A winch and small aircraft cable would work as well, as it can be crimped out of the way. As a last resort, you can screw the boards to the tires.
****IMPORTANT**** You must cover the tires with something (anything) light colored to prevent overheating of the soil and the plants.
Plastic pallet if you want to be able to move it later with a fork lift [optional]
Tools you'll need:
Jigsaw with a lot of carbide wood blades for cutting the sidewalls out
Wheelbarrow and shovel
6' Level or string level and string
Corded drill (no really, putting screws in rubber will destroy the trigger circuitry on a cordless)
Measure all your tires before you pick them! One of the things you'll notice at the tire shop is that the tires have no common diameter. In semi truck tires alone we've measured up to a foot in diameter. In order to stack properly, a tire must match the one below it in diameter by within an inch, less if possible.
