- Fit a corny, ball-lock keg into a cooler (48 quart/45L)
- Use a single 20 or 24 ounce C02 tank (paintball) as it should get me through a single keg for pouring
- Keep the beer/gas lines inside the cooler.
- Make it handy/re-usable for other outings
Other thoughts:
- I would pre/force carb and pressurize the keg with my 5 pound C02 tank.
- Pack any remaining space with ice.
- Possibly port the beer line.
- Bungie / secure it like mad
The canoe run I do isn't overly difficult and always a fun time. After some thought, I decided it would be best to try and keep the keg upright. Gentlemen, I give you my solution:

It's about 4 to 5 inches short, but I'm making it work. I picked one up at Kent. I'd like to note that the bin itself sits nice and snug in a standard milk crate. Might be good for stabilizing in the canoe.

I spray foamed in the deepest part of the bin and also added some flat packing foam at the very bottom. The picnic tap and lines I ordered arrived in the mail. I also acquired a paintball c02 tank adaptor so it fits onto the regulator. The tank fits well in both back corners of the bin even with the keg in place. I think I will add a shelf/container to raise it up a little from the bottom of the bin, keep it separated from the ice and to prevent the tank from tipping over.
Before the hardware arrived, I had made a cap with the bottom of a bucket and Styrofoam which I then spray painted to an almost matched green. Once the ball locks and lines were put on the keg, however, I found I did not have quite enough clearance so I may try to find some more scrap Styrofoam and double up the thickness, unless I can think of something better.
I also decided it was easier to widen the hole on the top and use the lid with the keg in place (Lines are a pain). Since the pics were taken below, I borrowed jigsaw and angle grinder to clean up the rough edges. Apologies for the crappy cell phone quality images.


Not quite finished, but getting there. Also, a small note, a bungee cord works well over the top between the handle and lid lock.
