Just putting this out there for you guys.

I recently built a small combustion and quickly realized I had a slight problem. The chamber is 1.5" sch 40. The problem I ran into was that I could not find a fan small enough for this chamber. I went to Wal - Mart and searched around and finally found something that worked. This link will take you to this company's sight:

I purchased the ipod looking fan (the motor fit in 1" pipe) and, after some modifications, it works nicely.

Like I said, I did have to modify to get the motor (cut the motor from the case, then make a blade). But it only cost me 3 bucks.

Heh, that's cool.
I dunno if the trouble of installing that fan was worth it though.
I mean, if your chamber's 1.5" how long can it be?
Most aerosal's spraying power probably mixes it very well.
I dunno. Mine's 1.5" * 3" and I don't use any fan. Just Lysol

Anyone that uses Methalated Spirits for fuel could find that misting fan very handy :)

I actually thought of that, too. But my little cannon is running off of propane. I probably could do without the fan and still get a goo shot but what the hell. I built a little bitty advanced combustion. :)
