Hey guys,
So I got my TapKing today, with 2 x bottles of Qld's finest. It seems like mrTbeer has done some awesome research and figured out how to hook up a minireg so that we can put in our homebrew, use 16g cylinders (threaded) and set our own volumes of CO2 (presumably).
I wanted to find out two things:
- the vol of CO2 that the beers come with; and
- the pressure of the regulator
So, sure you've all seen the front tap thingy down:
this tap thingy has a bit of tube in it, and when the TK bottle is engaged, a press on the TK tap lever thingy (not pull) pours out the beer. This tap elbow/nozzle I have removed to test, and connected some 3mm tube from Bunnings (pic below) to the tube from my regulator; see below:
Note that I cut the ball lock off this tube. This tube is 5/6mm PVC but I don't know much about it.
Pushing the nozzle down into the bottle allows the inside beer to flow, compresses the air in the tube and the regulator reads the pressure, which is...
...dammit, my regulator is shot. Can't remember the last time it was used, and I didn't test beforehand. Bugger.
But, the good news is this combination of tubing seals pretty well, even with only about 1" pushed into the tap nozzle and about 30-40mm pushed into the reg tube. The beer came down about 30-40cm, but there was plenty of air between the beer and the reg so no dramas about damage. So, you should be able to use the keg-side gauge of a regulator to find the pressure in these bottles. The temp they are at will then give you the volumes of CO2... cool.
This is the tubing from Bunnings. They also have 5mm tube, which appears to be the same stuff used from the regulator back into the beer within the TK head unit thingy:
5mm tube as seen through the cutaway:
So the plan was to pull the bottom bit of this out, insert 5mm Bunnings tube, insert 3mm tube as joiner into 5mm reg tube, connect a TK bottle (half empty or so) and read the pressure that the reg is set to. But again, reg stuffed.
I'll order another and update in the next week or so hopefully. Bugger.
actually - just realised... -
before you try this at home, you should probably use a t-piece for the cutaway pic above so that something is still connected to the beer side and it doesn't just piss out when you engage the TK.
