I saved all the parts except for the plastic because I knew I could end up using them later for other parts of the tank. So with all that out of the way, Let's build a tank!įirst thing to do was remove the batteries, controls, seat and plastic pits. I was home sick from work, throwing up with what was basically the flu. While I thought I was taking all the appropriate steps to avoid breathing in the fumes and had welded galvanized metal countless times before, I still messed up and took my mask off too early while cleaning up and ended up with zinc poisoning. You should try to avoid breathing in any fumes and a respirator is absolutely necessary. If you choose to use conduit and unistrut, there's a good chance you'll be welding galvanized metal. Welding galvanized metal sucks even more. T-shirt cannons are a lot of fun but could blow up or break something. This whole project was built out of some table talk, a great idea and some scribbles on a piece of paper, which was lost before the tank was even finished! My goal was to make it drivable with the operator completely hidden, allow the turret to spin, and have reloadable "shells" for the cannon.Ī good reminder is that you can build great things even if you aren't proficient with programs such as CAD. The coraplast is short for corrugated plastic pretty much plastic cardboard and is similar to foam board. The unistrut and conduit were left over from previous projects and helped to keep the cost down for this one. It's often used for suspending things like pipe and electrical in buildings.
Unistrut is metal that is basically square tubing, but with a notch in one side. The scooter was the kind that turns on a dime (just like a tank!) and is operated with a joystick.
I had an old mobility scooter I could use, was given some metal unistrut (strut) and electrical conduit, and told we could get some coraplast to make the skin of the tank. The only parameters I was given was it had to fit through a double set of doors and it had to be able to shoot t-shirts and beef sticks. Recently, I was asked to build a tank for a men's event I was helping with at my church.
