    I think the details of my vent are in the archives, but I can't
    ignore a challenge based on my own "survey"! I have a very effective
    vent system that looks like hell, but it was cheap and easy. I bought
    an enclosed blower (round inlet, round outlet, powerful and quiet)
    from American Science and Surplus for $15. They don't currently list
    them in their site or catalog, but something similar should be
    available from Grainger or other supplier. I used dryer hose, the
    flexible round metal kind, and hose clamps plus duct tape to run from
    the fan out, and from my desk, um, bench to the blower, so the fan
    can sit still, and I can move the intake. At the intake end, I used
    heating and cooling duct parts from the home center to expand the
    hose to a galvanized steel box, maybe 10" x 15", that sits right
    behind where I'm working. Smoke and fumes make a straight line right
    into the vent. The fan is quiet, but the air is noisy, so I plugged
    it into a switch which in turn plugs into a power strip conveniently
    placed so I can turn it on and off as needed. This doesn't vent my
    pickle pot, but I use citric acid, and keep it covered. I don't
    actually do much buffing, believe it or not. So this setup works well
    for me, and cost almost nothing. I already had a roof outlet for my
    ceramic kiln's vent, so I just switched it over. I feel very
    comfortable knowing that the fumes are removed, not just diluted.
