Wesley's Weekly HOW TO: Flag Gun Part II
POSTED BY Wesley Scoggins, 23 July 2008
Last week I showed a very simple design for a Flag Ejecting Gun, this week i'm giving you something extra by showing you how to make a trigger mechanism for it so you can actually fire it without having to hold the pull string taunt all the time.
First start out with a L-Brace you can get at your local hardware store, and a wooden dowel that can fit through it (it'll probably be a bit snug, that's exactly how you want it, you don't want it real loose.
Get a drill approximately the same diameter of the wooden dowel.
Pull the flag core all the way into the gun using the pull string, and measure about where the butt of the core dowel is when you pull it all the way back, and drill a hole all the way through the "barrel" of the gun that you can stick the dowel all the way through.
Mark a segment on top of the barrel.
And cut it off, I used a jig saw to remove the top, but if you have a thinner cardboard or different material for the tube, you might want to go with a different cutting method.
In the segment you cut off, drill two holes in the segment that is going to be facing forward, i'll explain why in a little while.
After running the dowel through the L-Brace, Put some rubber grommets on either end of the dowel on both sides of the barrel, this keeps the dowel from slipping around to much while you're working on the triggering mechanism.
Sketch out a trigger shape into something substantial, like some thicker cardboard or foamboard, not just poster paper.
Run the L-Brace into the "handle" of the gun, (I cut the handle apart so I could work with it.) then attach the foam trigger to the L-Brace. I attached it with hot glue.
Then I reinforced the entire section with some epoxy.
I then attached a wooden cube (I cut off of a piece of wood trim) onto the top of the L-Brace with more Epoxy.
On the base of the flag core, I attached another piece of wood, also with Epoxy, so it catches onto the other piece of wood when you pull it all the way back. When you get it "caught" on the trigger, all you have to do is pull the trigger, it will shift the bottom catch and release the flag shooting it out.
BUT, you'll have to reset the trigger each time, to keep it up so you don't have to reach in and manually put it on the catch, you have to have some kind of tension pulling the trigger upwards so it holds the catch in place until you pull the trigger.
I ran a rubberband through a hole in the L-Brace, keeping it in place with little bit of hot glue.
I then ran the two ends of the rubber band through each hole I had drilled in the top segment I had cut off earlier. The tension of the rubber bands keeps the segment in place, and holds the trigger mechanism up with tension, allowing it to automatically push it back up and letting the flag mechanism re-catch on it without having to reset it each time.
And there you go, after that, I put the handle back together, and now I can seal up the seams with some plaster, and give it a final paint job, and the build is complete.

thats awesome and will take effort and a while to build but it cool

wow, that is a real frankenstein project... Not the usual awesome project Wess, but thanks anyway for your effort.
Pretty cool.
nice
