Haughty Hand-Held Howitzer V2.0

Unread postAuthor: Zorrowannabe9 » Sat Sep 09, 2006 5:47 pm

<b>Haughty Hand-Held Howitzer 2.0</b>
<b>Description</b> - Propane powered combustion constructed primarily of ABS. The Original 4H was in need of some serious overhaul and cleaning. When I began to disassemble the chamber, I quickly decided to upgrade it to a 4" chamber. This time I planned on using more nuts and bolts to secure things, so that the maintenance and cleaning would be much easier to do later. The cannon was redesigned to be comfortable and light while still sporting all the "bells and whistles" that come along with combustions. The chamber fan was upgraded to fit the new chamber diameter, and a control box was constructed for the switch and power source. The handle is bolted on, and constructed of PVC 1" pipe screwed together, to be taken apart easily if wiring is ever in need of maintanence.

<b>Combustion Chamber</b> - 15" x 4"
<b>Barrel</b> - 60" x 2" (features stenciled name, and vented muzzle)
<b>Ignition</b> - BBQ ignitor producing dual sparks near the rear.
<b>Primary Fuel</b> - Propane Injection (no meter, just guestimation timing)


<i> full gun shot, barrel was never repainted after last launch</i>

<i> Why the radiation tape?</i>
Because I had it, and a friend mentioned that this looked like it belonged in <u>Ghost Busters</u>, so I slapped it on.

<i> Where did you get that radiation caution tape?</i>
I recieved it for Christmas a few years back from a friend of my mother's. Where she got it? I have no idea.

killagorrila, "damn" is still not spelled with a "<a href="http://dictionary.reference.com/search?q=damb&x=0&y=0">B</a>".

Hasn't that launcher been posted before? Or was that just on Spudtech?

Let me ask a question (as if you could NOT let me ... :) )

In the combustion chamber, there is a fan. WTF is that for ?

The fan is at the back of the cannon. It is used for mixing the gas and air for better combustion when the chamber is sealed and venting the chamber after the combustion has taken place. It isn't neccesary but it is better.
