I recently came across a small PC fan, little over an inch tall, and about a quarter inch thick. I rigged it up to where the fan and all the wires/battery/switch are on the end cap.

I know it does'nt do much for venting the chamber out after a shot but it still mixes the fuel and air.

Works fine for me, and I mainly did it cause I did'nt want more holes in my gun than needed. I'd have pictures up, but my scanner's USB cable is gone thanks to my brother.

Any thoughts on an end cap mounted fan, mainly safety and all that good business.

Unless you have a auto feeding barrel of some sort, the fumes should be able to exit the via the barrel. Ive always wanted to do this...

Well, the cannon was built with a 12 inch chamber and 4 foot barrel. I did'nt see this little one inch fan doing an amazing fume job. I just un cap it and set it on the ground while I found a good potato and get the propane ready.

Im trying to get pics up in the next day or so.
