Ride of the Valkyries

So, sometimes, I just have to stop and admit that I have a pretty awesome job. I work for a big box hardware store, as a technician in our Tool Rental department. I get all the general handy man projects around the store, and I was asked to build a tank for a competition between stores that is held every year. This thing is my baby, I’ve spent the last week and a half building this in between my normal work.

The cannon, which actually fires, is two inch PVC and has three and four inch PVC around it stepped down to the end of the barrel. The gun itself is a modified PVC t-shirt cannon, many of you have probably seen one on Make’s website. The valve is triggered with two 6v lantern batteries in series. The tank had to be parallel with the rest of the cannon so there’s room in the cockpit for a driver. I just added a 90 degree fitting after the solenoid valve.

The cockpit actually swivels, it sits on top of four casters and is guided by two galvanized pipes that sit in a circle cut on the top of the main body. The barrel tilts up and down hinged on two more pieces of pipe. The cockpit is made from two octagons, the one on the bottom is slightly elongated in the front in order to add a curvature. The curvature is achieved using 1/8″ Masonite, I attached it to the bottom and bent it onto the top. All the seams were filled with caulk give the illusion of welds.

The powerhouse behind it is a 3000 watt Honda generator fitted into the back. I added a long tail pipe to the end of the muffler to vent the exhaust out the back for the driver. Hooked up to the generator are the two front lamps, which are 250w halogen work lights painted black with high temp paint. It also powers the small air compressor in the front which is used to fill the PVC tank before the gun is fired. The filling system includes a modified tire filler with built in gauge so the driver can see and adjust the pressure as needed.

The main body was built around a lumber cart intended for flat goods like plywood and drywall. The frame is secured to it using metal strapping. The wheels are buckets spray painted black and the track is made from cedar edging painted black and silver. While I built almost the entire thing myself, I did have helping hands and helping minds for some of the creative pieces, but the awesome paint job was done by a fellow rental associate who’s an ex marine. He used camo paint and a faux brown stone paint to add the illusion of mud spray on the tracks and underside.

It’s really a testament to how great things can turn out when people put their heads and skills together. It’s was an extraordinary opportunity, and I’m extremely proud of how it turned out. I hope you guys enjoy the gallery below half as much as I enjoyed making this.
