Default Homemade carbonator cap


Air Chuck -- $2 (Lowes #3626 / 104ZN-RET)
1/4" x 1/4" Flare-to-Male Pipe Half Union (Lowes: #WATTS PB48)
Barbed Swivel Nut 5/16" barb to 1/4" FFL -- $3.25 (LHBS)
Tire Stem Valve -- $1 (Belle Tire)
2-Liter Soda Bottles & Caps

I also used a stainless T between my regulator and air chuck, so i don't have to constantly disconnect a gas QD to use it.

For the cost of The Carbonator, you can setup your CO2 and make 3-4 caps

Very cool. May have to make a bunch of these. Could also put some cool valve caps on top...

Nice! Now when you fill this thing up with beer and you wanna start carbing it do you use the same pressure as when carbing a keg? Same basic priciple as force carbing a keg and shaking it right?

I fill them with precarbed beer using BM's Beergun, then just drop 15psi on them to keep them carbed. No sense if using these to carb beer if you already have a kegorator. You can use these to carb up some homemade soda.

I must disagree on that reply I say this is a great idea when bringing a couple samples over to a party or friends house for the evening, simple small and cheap. The only expense is the valve stem price if a bottle was left behind or lost. So easy to take 3 or 4 different 2 litre brews along vs transporting 5 gallon corny's. I'm not rich enough and crazy to pay the price for2 or 3 gallon corny's. Nice to have yes but not the asking price of them.

I've made several, super quick and cheap. They work better than the commercial (expensive) type in that they seal more easily to the bottle. I have to take a wrench with me to use those. These are so cheap that losing a couple doesn't cause heartburn.

Dude, reread Arkadors post all he is saying is if you already have a kegorator then you dont need to force carb the beer in the bottle just transfer and then top off using 15 psi with the cap to keep it carbed .

I am going to build some of these this weekend amongst the 100 other things on the list...ohh crazy me with four 3 gallon corny's

These are good if you make a little more than 5 gallons per batch and then carb a few bottles without the wait for the priming sugar. It's also a good way to get a preview of the beer you just kegged.

Just wondering what kind of material the valve stems were made out of, should it be made out of stainless steel valve stems, or will brass be ok with the beer, or aluminum or chrome plated? or will any of them work? must protect the beer!

thanks!
