Know of a way to make some assembly procedures easier? How about how to make a better sparker. This is the place to share and ask specific questions on design, assembly and use of all types of spud guns.

I have the same question. a few bags of spuds ago I built my first spud launcher. Combustion model with spark plug in the chamber with grill ignitor on the trigger. Inject hairspray(the cheaper the better $1.99 can) close up the back, press the trigger. Sometimes first time but a lot of the times many pushes of the button before it’ll fire. Anybody got any feed back? I have a photo of the assembled unit if anybody’s interested.
Well, Two Things about hairspray. One, it will gum up the igniter. When the fuel in the spray burns off, then the igniter and the inside of your cannon, as well as, the twist cap is left to deal with the sticky residue. Ugh! I fix to this problem is that most aerosols are lighter than air. So by positioning you sparker at the top of the cannon will make for an 75-77 percent sparking to ignition ratio. that is if you clean it every time. I have no problems with mine. and I will explain in step Two. My igniter is positioned on the bottom. What, I just said to position it on the top? Well, that is because I use right guard deoderant. This fuel is heavier than air. You will find that you ratio is much higher. I hope this helps. If you do not want to spend the time with fixing the postion of your igniter then switching fuels is reccommended. Before you do that, use warm water and soak the interior of your cannon to get rid of the gunky build up. Spray Starch is an option. So is bug spray, however, that gives off toxic fumes and is not conducive to firing in doors. Just kidding regarding firing in doors.
I would definately like to put your pictures on my how to section of my website itself. go to http://www.spudgunextreme.com and click on contact us section of the site. Include in your email your name, city, and style cannon along with the pictures. Thanks.
With regards to using bug spray/repelant, I would avoid using it entirely due to the fact that DEET (the chemical that repels bugs) can desolve most plastics, including PVC. Unless you want your combustion chamber to eventually disolve, I’d stick with the spray deodorant or my personal favorite Static Guard.
