After a month and a half of work my potato gun is finally finished. I unveiled it at our recent monthly Halo day. It looks good and my friends thought so as well. The only problem is the stupid thing won’t fire! The BBQ igniter I used worked fine when I was test firing it. But when I test fired it I hooked it up to the short wires connected to the ignition chamber so the charge didn’t have to travel but a short distance. The design requires the trigger to be about two feet away from the ignition chamber. The screws in the ignition chamber had about a 1/4″ gap between them and they worked fine. Once the trigger was moved farther away from the chamber, the charge couldn’t jump that gap and so I had to make the screws so close they almost touched just to get the spark. Well the spark is now too small to ignite the hairspray. All that work and nothing to show for it but a replica of one of my favorite weapons from Halo 3.
I haven’t given up on it yet. I intend to find some other way to send a charge to the chamber. Or maybe use another fuel source that is finer than hairspray. I don’t know a lot about potato guns and don’t want to try something that could literally blow up in my face because the ignition chamber is right beside your head when you hold the M41-PG.
Hardcore Halo junkies can probably pick out the inconsistencies with my replica. Heck, I can. For starters the paint job is lacking in details like the decals on the launcher itself. The only decal I attempted was the SPNKr logo and you can’t see it from this side of the photo. I intended to do some more detail work but probably won’t unless I can get the thing to work. To make the potato gun look like the M41 I had to do a little cosmetic work. The potato gun barrel is actually 1″ pipe and the ignition chamber is 2″ pipe. But I had to cover the 1″ with 2″ to give it the right look. I could have used bigger pipe but that would make the replica way too big and its already huge.













Wow, this is awesome. Do you have any pictures of the making of?
This was the most ridiculous waste of time and money (even though it looks pretty good. I need something stronger to charge it because the normal BBQ lighter won’t travel the distance of the wires running from the trigger to the ignition chambers on the back. Now it’s just sitting in a storage shed collecting dust…shame. I don’t have any pics of the making, but I could take it apart and shows some pics of the inside.
