Re: CO2 adapter? The results

Well that was a perfect project for a long lunch hour! The victim was an
old ISI soda siphon. I took an empty CO2 cartridge and drilled the back end
to 1/4". Inserted a piece of copper tube and brazed it in place. Then I
drilled a hole in the end of the recharging cap and fit the cartridge/tube
in it. Put a flare fitting on the other end to fit an old NO2 gauge and
changed out the gauge's tank fitting for CO2. (It pays to have a good
junk collection.)

Filled the siphon with cold water from the refrigerator dispenser and
plugged everything up. Ran the regulator up to 100psi and nothing happened!
Disassembled the siphon and used an air gun to see if it was plugged. It
appears that the valve in the charging port will not open below about
125PSI. SO I put it all back together and ran the regulator up to 250PSI
and it bubbled nicely. After about 5 minutes the bubbles stopped and Bingo!
Soda water!

The CO2 cylinder is an industrial K size and still has about 50 pounds of
gas so at 8 grams per charge I should be able to make enough seltzer for
about 1400 liters of Scotch. :-)
