Quadzilla

Unread postAuthor: PCGUY » Sat Feb 12, 2005 8:43 pm

<div align="center">QUADZILLA

Provided by Boogieman - <a href="http://www.advancedspuds.com/">http://www.advancedspuds.com/</a>

This cannon is called Quadzilla because comes from the fact that there are 4 sparks inside the chamber that spark simultaneously from a 200,00V stun gun system, and all of the electrodes are stainless steel. This chamber includes a fan to help the fuel mixing and exhausting gasses. It is a breechloader that uses cam lever couplings in the breech loading system. There is no on-board propane meter, so the overall weight of the cannon is fairly light. This cannon also has a stand, as you can see in the pictures, which allows for persists changes when shooting for distance.

This cannon was also painted with <a href="http://www.krylon.com/product/gp_product_detail.asp?sgID=GP07">Krylon Fusion</a> paint which is the perfect choice for all plastic spud cannons. There are multiple barrel attachments too, like a Breech Loadable Rifled 1.5" SCH 40, Breech Loadable Smoothbore 1.5" SCH 40, Sleeved Golf Ball Barrel, and 2.5" SCH 40 Tennis ball barrel. This gun can also use the burst disk attachment and its various size barrels. Quadzilla will soon be getting a 3" barrel for pop cans/bottles and a 2" barrel for limes and large spuds.

The COUPLER is there so he can put the bolts through a double thickness of pipe. (ok, the coupler's a fitting, not a pipe, but whatever) This is recomended, as it lowers the chance of the electrode coming out or the pipe failing.

All pipe and pipe fittings are put together by using primer and cement. In the Quadzilla his method of ignition required him to put screws through the chamber that would carry an electric current and provide a spark inside the chamber.

Since putting any kind of hole in your chamber isn't a good idea, he decided to use couplers to ensure that where he needed to make a hole and put a screw, the PVC would be twice as thick for added safety (pipe slides inside of couplers and is glued there, making parts of the piece twice as thick).
