An improvement of the howtoons launch pad for the soda bottle rocket. While it worked in unison with the trigger quite good and was accesible and easy to make, I found that it didn't hold the bottle the best and flopped around quite a bit. Here is my version of the launch pad for "Soda Bottle Rocket".
I didn't include instructions for sawing the pieces, only the measurements. Why would I need instructions for sawing?
I also just figured out that it makes a handy foot rest :) Don't use it for standing on though! It could easily break under that kind of pressure.
Square-ish type piece of wood, can be rectangular, not too rectangular though. I used approx. 6 inches by 9 inches (that's 15cm by 23 cm).
Long rectangle pieces of wood. I used 5 inches by 12 inches (13cm by 31cm). DO NOT make it any shorter than 5 inches (13cm) high. If it is, you might not be able to fit your bike valve and pump head under it.
Screws or nails
Drill press or other tool used for making large holes
1 inch drill bit for drill press
Screwdriver or hammer
Step 1: Drill the Hole
Using the drill press or whatever you're using drill a 1 INCH hole. I mean it. 1 inch. Not 1.2 inches. Not 0.9 inches. 1 INCH. If you do this wrong it could totally wreck the launch. Unless you want a ballistic rocket flipping over and flying at the person who's pumping, don't screw this up.
Step 2: Nail/Screw It Together
Nail or screw the thing together the thing together. I used three for each side. Keep it simple.
