grips for combustion

Unread postAuthor: the_beaver689 » Thu May 17, 2007 5:33 pm

I am in the process od building a combustion launcher with stungun ignition, propane metering, and a chamber fan. I have looked at many other lauchers for inspiration and I was wondering, what is the most prefered method for making grips?

I was thinking of using a tee fitting, cut in half, and using hose clamps attached to the chamber.
Are there any better way to do this? Any info is greatly appriciated.

thats exactly how i do it, but i connect a elbow to the tee that way it is like a m-16 grip, it is also much more comfortable to hold and fire than a vertical grip.

That's exactly what I did. I got 2" x 1.5" Ts, they're 2" on the "left and right arms" and 1.5" on the "down arm". 1.5" is a good size for the grip. I sawed them in half the long way on the 2" side, and used a file/ruler to get them smooth and level. Then I used big black industrial zip ties (hose clamps would be fine too) to secure it to the chamber. I was able to get my ignition circuit contained entirely in one handle, and my fan controller and batteries in another handle. Works out great.

I've seen nice handles made from wood, too.

If I build another (or seriously re-model my current) combustion gun, I'd set it up to be held down at the waist, with the grips on top (like miniguns in video games).

Peace,
Pete Zaria.

You can also use 3/4" pipe, a T and end caps.

Extend the top of the T with a couple inches of pipe and an end cap in one direction. A standard BBQ piezo's fit perfectly into 3/4" SCH40 pipe. So, insert a short (~1") length of pipe into the other end of the top of the T to hold the piezo. Run the wires through the top of the T and the longer piece of pipe and finally out a hole (or two) in the cap at the other end of the top of the T.

Use big-ass hose clamps to hold the top of the T to the chamber.

A vertical piece of pipe from the T is the handle, capped if you prefer.

If you replace the T with a Y you can get the handle at 45 degrees instead of 90. (but the piezo button might not be in a nice place)

burntlatke.com has instructions on a pacific and guano grip both look nice and are fairly easy to make
