Well, I was thinking it over last night.... since my C02 tank and regulator are set up to carbonate 2 or 3 liter bottles directly, then I could just use the 2 or 3 liter bottle for a pressure vessel instead of a keg and use a y adapter to hook up three tubing lines that connect to 1) Co2 tank/regulator, 2) 2 or 3 liter bottle (which i already made an airtight attachment for) and 3) the beer bottle - this tubing line will have picnic faucet, drilled stopper, racking cane. I would hope gravity would allow the carbonated drink to flow from the 3 liter plastic bottle to the glass bottle without a problem. I also would hope the pressure from the CO2 source would keep it from backflowing into the CO2 line. I can adjust the drilled stopper to let out excess gas, I think. I've seen someone do that.
Haha this will be quite a contraption and I'll let you know if it works, the problems etc. after I have it made and test it out. I'll definitely be wearing Personal Protective Equipment! Please don't hesitate to let me know if you think there's obvious problems I should consider. This idea is kind of out there and I wouldn't take offense!
