Step 1Procuring your Precious Parts...
- CO2 regulator, available for $38.95 from BeverageFactory.com or $50 from Kegworks.com...
- CO2 Tank; either ask to put a deposit on a 20lb CO2 tank for around $100 at a local beverage supply, bar supply, restaurant supply, soft drink, or beer distributor in your area, OR buy your own for around $100 from BeverageFactory.com (according to a hot tip from user Greenbriel, their prices are lower on ebay than on their website, and they will pricematch with their own ebay store...based on feedback from users, you likely won't get your original tank back if you swap it out for a new tank; price out the options based on CO2 suppliers in your area...Regardless of whether you end up buying or putting a deposit on a tank, you can swap out empty tanks for about $15. To find a supplier, call around, search google maps, be creative; as an example, Barmade, the bar products company that I found in Los Angeles was very helpful...
- Locking Ball Chuck, either available at Harbor Freight or Monkey Grip part #M8871, available online or in stores at Kragen Auto Parts...in testing, users have said that the Kragen/PartsAmerica locking ball chuck wasn't as sturdy as the Harbor Freight chuck...and it's also an excuse to visit the tool mecca of Harbor Freight.
******Update! Harbor Freight has put out a coupon through August 15 for a Locking Ball Chuck for 99 CENTS! (you might get them to honor it even after the 15th?) Check it out here...
The picture of the coupon is also below in case they take it down after the 15th...
- Monkey Grip Rubberized Snap-In Tire Valve part #M4130, available online or in stores at Kragen Auto Parts...
- 1/4" Threaded Full-Port Ball Valve (inline shut-off valve), available at Home Depot...The part number is 107-701HC; the SKU on the bar code appears to be 32888 07701...
- 10 foot roll of braided vinyl tubing, 1/4" internal diameter, available at Home Depot...The external diameter of this tubing is 1/2"...
- (3) hose barb adapters, 1/4" barb x 1/4" MIP, available at Home Depot...This part is a "Watts A-192" or "A-192/225." Do not get the "192B"...
- (4) 9/16" hose clamps, available at Home Depot...I found these in a package of 10, with a listed "range" of 1/4 to 5/8.
- (3) 3/4" plastic pipe clamps, available at Home Depot...
- roll of 1/2" teflon tape...
- a 2 liter bottle and cap.
Note:
After completing this instructable, I happened across an attachment for a screw-cap bottle that's not quite as DIY, but slightly more elegant (and slightly more expensive) than the tire valve solution...I haven't tested this option at all, but I'd assume it would work as an alternative...
