I updated this on 1-27-14 with somethings I learned while using it:
-The Edgestar tap is good, but the regulator is a pain. Buy a real one, and the basic adapter to paintball CO2 route if you go that way.
-Don't bother with the glue
-If you go with Edgestar regulator check the comments for fittings.
I got this idea from: https://www.youtube.com/watch?v=JbLjPP7W5Q4
Step 1: Gather Needed Items
Krups Beertender (model B100)
The Edge Star Mini-Keg Conversion Kit
Drill - If you have a right angle drill, i would use it. Space is very limited
1/8" Drill Bit
7/32" Drill Bit
1/4" Drill Bit
*Loctite Clear Silicone Water Proof for Aquariums (if you are able to find specifically food grade sealant, I would use that. However, the aquarium sealant is perfectly safe once cured)
*This isn't needed and this is what came apart when I had a regulator fail. I rely on friction and have had no problems
*The 'Adapter II' (make sure it goes paintball to 1/4" right-hand threaded)
*Brass 1/4" to 1/8" Reducer
*Brass 1/8" to 1/8" (short)
20 oz CO2 Paintball Tank
*See comments regarding beer gun regulator nut and 1/4" to 1/4" npt
**I had some major problems with the EdgeStar Regulator and went to a normal regulator and adapter for the paintball co2 tank.
My local sports store sold me a tank for around $25. I switched to this, because the 16g CO2 cartridges run you about $2 a piece, and it costs about $5 to fill the much larger canister. It should save money in the long run
Please keep in mind, with the larger CO2 tank you are dealing with very high air pressure. I used brass fittings, since they can take the pressure. I wouldn't use plastic or PVC on the tank side of the regulator.
