I've been thinking about this idea now for ages. Turning a 25L Jerrycan into a fully functional Co2 injected keg at low cost. I'm happy to say I've succeeded!

Attach a screw on Co2 tyre inflator with 16g Co2 canister attached: £8.89 delivered - http://www.ebay.co.uk/itm/140827604903? ... 1423.l2649

And you've got yourself a JerryKeg for £21.87!



Simply screw the injector valve slowly to release Co2 into the keg. Keg holds up to around 6psi comfortably. Mine is reading 9 at the min but I think there's something up with my reader.
I've only started using this so am unsure how long a 16g bulb lasts etc. My plan is to prime with 30g and leave for a week. Can usually get through between 1/4 and 1/3 of the keg before I have to open the cap to let air in. Not any more!

I'll update here as I use it more. Either way... a f*cking bargain Co2 injected keg whatever way you look at it!
Let me know what you think.
