Great job Adrian. Are we sure that there's nothing else from peroxide that could cause oxidation? My quick skim of wiki on methylene blue indicates that it does go blue in any oxidative environment. Interesting that you can create peroxides from it too. Anyway, I'll pipe down as I'm a...

Good stuff. Yeah with cable pulling the devil really is in the detail. Can be really quick (and cheap) if it's an area with good access. If it's a rabbit warren or a long run, it's going to take a lot longer

Yeah, you can see why the availability and capacity of industrial utilities are often the first thing to limit a brewery's output. A single refrigeration compressor at a large brewery can easily draw 400A on its own.

You're sailing very close to the wind indeed, and this is the exact reason why I moved from electric to gas on the kettle. I still have an electric HLT and HERMS. Your household wiring will cause an unacceptably high voltage drop and in turn get rather hot. If you have insulation in your walls...

If you're not experienced with electronics, the one thing to make sure you nail is the circuit breaker/RCD (different things but can be one combined into 1 component these days) and earthing. Then at least you know you're not going to burn the house down. I'd get a CB/RCB combo for each main...

Known as seamers in the industry. I'm lucky cos I get to play with industrial-sized ones. https://www.youtube.com/watch?v=V_02BjDtqtA

While they are obviously doing it for business reasons (ie not charitable), I agree with Lion/Chuck on this one. The whole "craft" thing is just a joke, similar to "organic". That said I don't like how they do throw their weight around, but let's be honest: Lion can produce a keg of beer for...

I'd recommend a cold mash in. Then, if you're really super-duper keen, you can build a mechamasher which is what's used industrially. This is an auger inside a pipe which mixes the incoming grist with strike water, and the mixed slurry flows into the mash tun. This'll get your mash all nicely...

That's my whole point though, bigger doesn't mean better. You can get the biggest fridge system ever built, but if its suction and evaporation pressures aren't set up around your duty point then it can never get there. A freezer isn't just a more powerful fridge, for example. A freezer has a...

Clever idea, but I don't know how many leaks I have. I know it's definitely more than 1. They're very, very slow indeed. For all I know it could be a systematic issue with all the hose clamps or disconnects.

I did. Picking up sunday. I knew that box of old triclover clamps I had lying around from work would eventually come in handy!

Haha thanks Grott. I've completed one 24 hr pressure test on line "C". There are 7 other lines, so this will take some time :(

Super cheap auto has enough metal polishing tools and consumables to choose the right one from. Can't tell you off the top of my head sorry. In saying that, it sounds like the heat affected area of the weld. In this case it may have to be pickled instead. This involves applying pickling paste...

Cool stuff. When's the brewery intended to move on from proposal-on-paper to project-in-construction?

Based on my experience with triclovers I am a little worried that simply using the clamp to hold the separated bits of tube (with adhesive) will be a bit physically weak. Pushing on and off beer taps places quite a bit of force and torque on the font. Triclovers are strong if the triclover...

You can't just chop stainless and join it again with a triclover. You need to weld on the triclover connections (with argon purge), and then pickle them. Apologies if you know this. stainless welding of tube is NOT for the beginner. If the font chrome-plated brass, you're going to deeply regret...

... I think I got a bit carried away when I thought I needed a whole sack of biscuit... Just cleaning up. PALLET 1 - Joe White/Best Maltz/Simpson/Briess etc 1. PRATTY - Joe White Pilsner 2. PRATTY - Simpson Maris Otter 3. PRATTY - Joe White Vienna - 1/2 bag (split with MATTYH77 ) 4.BREWHART -...

Yeah I've SMSd him. :beerbang:

:ph34r:

This is also how I feel at the moment. 24 hour Pressure test on bottle and regulator - pass 24 hour pressure test on lines - all isolated at manifold - pass Soap test on all joins; isolated at manifold - pass Soaped 2 kegs (the only kegs I have full ATM) - found one leak in lid. Re-seated lid...
