Thanks for the replies, I will investigate! Cheers, Pete

Hi Guys, I am about to start brewing the aforementioned kit. 40 pints at 4.5%. I prefer my tipple to be around 3.5 to 3.8%. Rather than just adding more water at the start, (how much water?) is there anything else I should add to keep the taste? Don't want to just end up with a "watery" version...

Hi Drunkula, I already have a schrader valve and a 15psi pressure relief valve fitted to my lids. If I was to get a CO2 fire extinguisher, are they easy to get refilled, especially if they have been modified? I'm an engineer, so not difficult to do mods, but unsure of regulator type...

Hi Guys, I have a couple of King kegs with S30 CO2 connections. Just wondering if there is any more cost effective CO2 options rather than continually buying bottle refills? Cheers, Pete

Certainly made me get my finger out to modify the keg caps 🤣

Hi dwhite60, After the second fermentation in the barrel, I started to lose pressure. I obtained replacement square section O rings for the crap King keg cap and swapped them over, chucking in a little dissolved sugar to get a second secondary fermentation. I knew this was risking the batch but...

New cap arrangement sorted. I cut the top off the original cap, cut out 3mm to tighten threads and put lock wire round the old cap to keep tight. Then machined up the parts as per the photos. I filled the barrel up to the neck with water and pressure tested at 12psi. With such a small air...

Hi Buffers Brewery, I love your mod, it has given me a few good ideas as well. I like the cut cap held with a jubilee clip, much easier than a split clamp. The wing nuts are also a good idea. I'll get to work on mine next weekend. Got house eves to paint first 😕 Cheers, Pete

Hi Buffers Brewery, Would be most interested in seeing your new cap. You have certainly got me thinking, a large diameter flat O ring and a flat stainless steel plate with my valves and guage fitted. A steel two piece steel band bolted to the bottom of the threads on the barrel with six or...

With the O ring removed, the cap screws down further. Pete

Hi Terrym, You have missed nothing, you are quite correct. If the two faces are as you say " two flat equidistant mating surfaces", you wouldn't need a gasket. But a softer gasket will take up the differences between the two. The trick is getting the two surfaces to as close as possible...

Hi Guys, Tested out the softer square section O ring, still leaking 😢 I need to check that the barrel lip is mating with the cap squarely, that's the next plan. Also to cut slots in the caps and feed lock wire round to get tighter threads. Starting to think I shouldn't have to do any of this...

Hi Buffers Brewery, Got the new square section O ring cut today using a softer silicone. Should get it tested tomorrow. I like the idea of cutting slots in the lid to tighten the threads. But rather than cutting the lugs the spanner fits onto, I will drill a small hole in each of the lugs and...

Hi Hazelwood Brewery, Have a look at my earlier posts, the pressure release rubber is long gone, it's such a poor system, I got shot of it right away! Experimenting with different O ring material now. The standard O ring and the replacement square section O rings are too hard in my humble...

Good point!

I also like your mod with the jubilee clip. I will cut slots in the lugs to feed the band round, that way it can't slip off and my spanner will still fit. Cheers, Pete

Hi Buffers Brewery, That makes perfect sense and would explain why the square O ring is no better Than the round section one. I will investigate that, thanks😉 Cheers, Pete

Hi Clint, I think the route cause of the leak is too hard a seal, be it a round or square section O ring. I have the kit for fabricating square section O rings from various flat rubber or silicon sheet. So the experimenting goes on. As a maintenance engineer for the last 45 years, I will not...

Hi Kelper, Ifyou have a look at my photo on an earlier post, you will see my modified cap. The original pressure relief valve has been blanked off and a professional 15psi relief valve fitted with a guage and O ring seal in the base. A schrader valve is also fitted for leak testing. The entire...

Hi Kelper, It is a genuine King keg. I have tried just hand tight to as tight as I can get it and everything I between, still leaks and that's with the square O ring. After everything I've tried, I'm down to liquid ptfe or a better quality cap. Currently trying out the ptfe, I'll report back...
