The problem is everyone is getting their hands in the punch, the stuff gets all over the place, no one is controlling it, and it just feels too much like a college party.
Now I wanted something to build that was useful, creative, unique and above all sets the standard for "not a typical college party".
Materials (all purchases at my local Lowe's):
3/8" Ball Valve #41977 $8.21
3/8" ID Tubing 25' #22273 $8.25
3/8" ID Adaptor #27971 (x2) $5.36
3/4" 90* Elbow PVC #23868 (x2) $0.60
3/4" PVC pipe >2' ---------- $1.50
Thread Seal #25010 $1.07
Epoxy Mix #20640 $3.77
Wood for Countertop
Large container for liquid
Brackets for Countertop
(Optional) Bracket for back of tap
1" Speedbore Bit
A means to cut the PVC
Step 1: Building the Tap
Use the 1" speedbore bit to cut a hole through the board. Now you will find the PVC shouldn't fit, PVC is measured by its Inner Diameter, the outter diameter is never exact, use sand paper or whatever means you have to slightly open the hole. You want it so the PVC fits very snug, the tighter the better secure it will be.
Once the PVC fits, feed it through till you meet the desired height you want for the tap, mark the PVC below the board and cut it to size. Mine worked out to be a tad over 12".
Step 2: Running the Tubing
Once you find the best fit area figure out how much tubing you will need. If there is no way to get the barrel upstairs you could even put a shelf above the bar as close to the ceiling as possible.
I calcuated my pressure to be around 4psi:
Density of liquid x Total height change = psi
.44 x 9' = 3.96 psi
Sure the equation isn't exact as I don't know what the final density of the liquid will be, and the height was calcuated from the bottom of the barrel to the end of the tap.
However as you will see on the final page it passes water with an amazing amount of force!
Step 3: Run the Tubing
Feed the tube up through the bottom of the PVC pipe. (Picture #1 and 2)
Once the tube is fed, put one of the 90* elbows on the top (Picture #3)
Now you will need to get some of the extra PVC pipe left over from when you cut the tap to height. Cut 2 small sections off of it so that you can extend the valve from the 90* elbow, approximately 2" long each (see Picture 7)
Now you need to assemble the valve assembly, make sure you put plenty of thread seal on and tighten them down. Once everything is epoxied in, there is no getting back to the thread if its leaking. (Picture #4)
Now take the 2 sections of PVC you cut and put them on either end of the valve, if one is shorter than the other like in my build, remember you want the valve standing straight up for off, and pull down toward you to start the flow!!!! Which for this model valve means handle on the right.
Use the epoxy to seal around the outside of the PVC and fill inside the PVC all around the threaded section, careful not to get any epoxy in or on the ribbed section where the tube attaches! (Picture #5)
Once the epoxy dries and the section is sturdy, finish the assembly as I have shown.
Step 4: Final Run and Finishing the Bar
Here is to show just how fast the flow rate is on this baby, it does come out rather quick and bubbles up the drink but I think with some tweaking it should work fine, and if I do keep it this fast who cares cause its only juice.
The last thing I have to add to this is a cooling system that will go directly below the tap to instantly chill the liquid before it is dispensed, aka ice cold drinks...without the ice :)
