alternatively, the original poster might be able to set up a slow drip of
vinegar over either just dry baking sode or a condensed baking soda
solution. i bet the rate of liquid drip would be easier than needle
valve regulation (that's pure speculation on my part). once it gets into
an air line, i suspect it would be the same as any DIT CO2 system.
