J&D Model I Potato Cannon Instructions
Above: Our equipment, in storage. The totally finished J&D Model I Potato Cannon is at the far right.
Here's what your gonna need to build your own J&D Model I Potato Cannon. Get your ass into the nearest Home Depot, Lowes, ACE, or any other place that would have some Schedule 40 PVC. Make sure its Schedule 40 or else you will be picking shards of PVC outta your arse after you light the damn thing! When you get there you will need to buy:
Since PVC usually only comes in 10 foot lenghts, you will need 10 feet of 4 inch PVC, 10 feet of 2 inch PVC, a 4 inch to 2 inch reducer, a 4 inch end piece, a 4 inch end cap, PVC glue, and a BBQ Lighter. [Make sure the reducer has a rim on the inside of it. Trust us!
Ok, so by now you've probibally checked out and are at home looking at a whole crap load of PVC and a lighter! Here's what to do with it:
Step #1: Cut 2 feet off of the 4 inch pipe with a hacksaw, and glue it to the 4 inch end piece.
Step #2: Now glue the reducer to the side of the 4 inch pipe without the end piece on it.
Step #3: Take the hacksaw, and cut 3 feet of the 2 inch PVC, and glue it to the reducer.
Step #4: Get the 4 inch end cap, and drill a hole in it big enough for the BBQ lighter to fit into. Then mount the BBQ lighter to the 4 inch end cap using the PVC glue.
Step #5: Take some sand paper that you have laying around, and sand the end of the barrel of the Potato Gun so that it is sharp enough to cut through a potato.
Step #6 --> Testing: BE CAREFUL!!! Take a piece of paper, and stuff it into the barrel of the Potato Cannon, use a broom to push it all the way to the back of the barrel but NOT into the 4 inch PVC!!!!! Remove the end cap. Take some hair spray [preferably 'Aqua Net' Hair Spray], or some GUM-out engine cleaner, and spray it into the 4 inch PVC through the hole for the end cap. Quickly screw on the end cap, point the Cannon up at a slight angle, and click the BBQ lighter. After 2 - 5 clicks, the Cannon should light, and shoot out the piece of paper with a loud thud. If not, remove the end cap, and check to see if the BBQ lighter is ignighting properly. NOTE: Some modifications may need to be made to the BBQ lighter!!! Soddering a piece of a paper clip to the ground wire solved the problem for us! Just make sure that when you click the lighter, a blue spark glows from the tip of the lighter, to the paper clip! Repeat the test again.
