Brush fans aren't as dangerous as people seem to think. Just take extra care while the fan is on, especially when you first turn it on, and it should be fine. Just don't mess around or point it anywhere that would be dangerous while the fan is mixing.

I have the same opinion like Jumping Jehosapat



And 99,9 % you need a big free overjumping spark at propan/air.
At my ignition i had sparks which creep and doenst jump free. 90% Nothing happened and possible sparks at the brushs are much smaller.

That shoulnd say that its impossible but nobody holds the gun on people :wink:


Nice Gun :)

Nice cannon! Now I see why you were asking me for a cannon barrel that went down to 3" threads, but I only have one, which is way to big for that lil' chamber, (2-1/2" x 60").

popomon, If you read the spudwiki, your question will be answered.
I wrote the page for chamber fans, and the answer you seek is included.
