I have a gravel drive that is convenient to the stoves, so for right now I just check he wind direction and let it fly, pun intended.
I just purchased an industrial dust collector with a cyclonic separator and 6" inlet on ebay. Am currently making a dump tray that will suck up the dust while dumping. I plan to collect the ash in barrels and spread it on the driveway when it gets icy. This unit will also be connected to the basement for boiler ash collection. If all goes well no more dumping ash and getting a dust cloud.
Matt, does that collector have an after-filter? If so, what is the micron rating?
Reason I ask is that I found the fly ash is SO fine that it went through a regular single ply industrial vacuum "trap-sack" filter bag. Fortunately, my super duper industrial vac has a secondary multi-layer cloth filter to catch it before it all flew into the room. I had to go and purchase some drywall dust style collection bags to be able to handle the fly ash. So far, so good. If you don't have any sort of super-fine filtering on that cyclone, make sure you blow it outside, as that is where most of the fine stuff is going to end up.
