The minute I saw "Mythbusters: The Search" I knew I had to make this. I had a limited amount of supplies and not a lot of time to go and get materials so I had to work with what I had.
Step 1: Materials
-1 2'x6' of 1'' board
-Bolts and nuts
Step 2: Tools
-A cutting tool(I used a sawsaw)
-drill or drill press
Step 3: Cut Your Board
All you have to do is cut a circle in the wood. The size of the circle is directly proportional to your weight. I weigh 150 lb and my circle is about 1 1/2' in diameter.
Step 4: Attach Your Foot Rest and Handle
The most important part of this step is making sure that the screws don't break through your circle. this will result in a loss of pressure.Your handle can be anything. Make a L shape at the bottom so you can rest your foot on it
Step 5: Drill Your Holes in the Circle
There needs to be two holes in the circle. One for the release valve and one for the hose.
Step 6: Attach Your Hose
All there is to this step is stick the hose in the hole and caulk around it for an airtight seal.
Step 7: Add the Release Valve
There are many ways to make a release valve. If you want to go find one on the internet, be my guest. I just used a plastic mouse trap with a circular piece of a sanding block on the end.
Step 8: Add the Vacuums
Just hook up the vacuums any way possible. Since all vacuums are different I cant tell you how to do this one. just make sure its airtight. Make sure you keep the on/off button.
Step 9: Add Gasket
For maximum suction, you need to add a gasket. I used a septic tank gasket and glued it onto my circle
Step 10: Add Foot Clamp
This allows you to lift up the suction cup with your feet as well as your hands. This could be anything from a zip tie to a boot screwed into it.
Step 11: Repeat
Repeat steps 3-10 for the second one. Stick the two vacuums in a backpack and plug them in. Now you're ready to scale a wall.
