Nice attachment, Rick. There was a time I was looking like that in Chem labs.
Here’s the setup for the barrel. A quart Mason jar with an aluminum foil shroud (owing to the high vapor pressure of the organic solvent mix). The shroud kept VOC evaporation to a minimum and I only had to top it off once during the 3 week soak. Setup was staged outdoors on a covered patio and away from a source of flame. Two of the three mix components were supplied by a friend in industry and the liquid was funneled into a metal storage container afterwards ….. never know when I might need it again.
