Agreed, a dust collector isn't really suited to what you're talking about. How 'bout getting a ventilator from Harbor Fright http://www.harborfreight.com/8-inch-...tor-97762.html and fun the fumes outside. This one is good for 1500 cfm which should do fine. With a 20% off coupon, it's about $65.

The downdraft table jody describes would be great, but you'd need a pretty capable blower to make it work.
