Being a lurker, I sometimes forget that I might should share things. So, today, after unloading more stuff from the Old Settler's Music Festival, I saw my portable keggerator and decided that I needed to share. A friend has christened it "Ned Keggy" after the Australian fellow with the funny outfit.
These coolers come without insulation in the lid, so that was fixed in the construction. This still has ice in it that was put there on Friday (4 days in the sun). The lid and tower are filled with insulative spray foam. It ain't pretty but it is bomb-proof and stays cold for a long damn time.
1 sheet metal place (approx. size of the lid)
Galvanized metal duct collar
Spare wood (2X2s and a 2X4 for the frame that the thumbscrews use to hold the bucket on top of the collar)
tap and hoses
paint ball tank
tee nuts and thumb screws
Basic build instructions.
Cut hole in lid. Cut hole in sheet metal. Place duct collar over the hole, place sheet metal over duct collar, drill holes around edge of sheet metal pop rivet in place. Screw three 2X2s and one 2X4 inside the collar (upright, height of the collar). Place bucket over collar, drill holes for thumb screws through bucket, collar and frame. Countersink the back of the holes for the tee nuts. Mark the location of the 2X4 in the bucket for the tap shank. Attach 2X4 to bucket and drill hole for shank. Fill the lid with spray foam and line the collar and bucket with spray foam, allow to cure. Carefully trim so that the foam in collar and bucket meet when placed together. Paint the foam for easier cleaning. Assemble tap, beer and gas lines. Caulk edges of the sheet metal place and any open spaces in lid.
Drip tray or bucket.
Something to hold the paintball tank inside the box.
Has run probably six corny kegs of drink (a few small meads, a small cyser, a Ranger IPA clone and a few of our House brown ales).
