If the geometry of the filter is a bit baffling in the photo above, this is one with the filter in-situ: 20200831_185856_WEB.jpg It wasn't my intention to include the old gauze "snorkel", but the filter was cut a bit short and the snorkel fills the space. With hindsight the snorkel relieves the filt...

More than two months later, the filter is built and in action: 20200829_160129_WEB.jpg Not before time: It's first job was for a 45L batch (+20L but same hops, 'cos this was a "parti-gyle" experiment too) of "historic" London Porter. Close on 1/2 kilo of leaf hops (it will block up with pellets, but...

I'm sure they are. There will be some leeway. Just as long as others reading this don't think there isn't an issue (they may not be so lucky).

Just like me suggesting you can screw male NPT (1/2" & 3/4") into female BSPP. It'll most likely work, but that doesn't make it right.

… Then there are the 5/16" (7.94mm) options, UNC/BSW at 18TPI, BSF at 22TPI, and UNF at 24TPI … Damn, missed British Standard Fine (BSF). Too late now, but I'll record the option here should I ever want to give it another go: https://www.ebay.co.uk/itm/5-16-BSF-Nuts-5-16-22-British-Standard-Fine-St...

Saw them, Amazon sell 'em. But they are best screwed into a threaded pipe fitting (a thermowell?) rather...

Angel Homebrew and Brewbuilder usually stock those type of probes. I must stop all this farting about; probe (1/4"BSP) ordered from Angel Homebrew (along with 14mm Q-max punch). He'll be amused, it's almost 3 years since he supplied the vessel drilled out to take these useless Chinese probes. Thank...

It could be an American thread (NTP?). Thanks. I looked it up because although it might not make sense to use a pipe thread in such a situation, it's just the sort of thing to expect from China. But in looking it up I was immediately reminded that NPT is a tapered thread. No luck there (the nut in ...

1/8 BSP?

Thanks. Haven't tried it, but 1/8bsp has 28tpi and a good bit larger than 8mm diameter (8.5 minor dia.). 5/16" UNC/UNF is 18/24tpi but both bind early. M8 is just over 20tpi and gives best fit so far, hence I think tpi is about 19-22.

Some controllers have a "dead-band" too deal with this, but not the ITC-308. I've fiddled with mine to try and reach a satisfactory compromise. 0.3C is a bit small, I've got mine set to larger differentials (but below 1.0) and not necessarily the same for heating and cooling. There's no point me dic...

I've an Inkbird PID. I need a stainless steel probe for the PID to fit into a HLT vessel, preferably RTD (PT100) type. Lots of probes on eBay, all from China. First one rusted all over within days. Second one remained shiny! But the nut attaching it rusted dramatically; it certainly isn't stainless ...

One problem I've had drawing together all this stuff about hydrometers: The theory is fine and it is all working as expected. But in the real world? It seems the (UK) scientific world is seemingly very much hanging on to the 60/60°F standard (hydrometers comply to a 15.6°C calibration and 15.6°C wat...

Just to expand on this subject of "reference density" to help you (and me!) understand it, here's some real-life examples of it applying. And yes it is applied to your hydrometer! But a hydrometer may be stuck with a scale using one reference density (e.g. home-brewing hydrometers). As a key: My pyc...

I'll list a few water reference densities you might come across (so I can refer to this record too!): Pure water @ 4°C (3.98°C) is 1.000g/ml (the default for laboratory or "scientific" hydrometers). Pure water @ 60°F (15.55 or 16°C) is 0.999g/ml (older and perhaps some country "default" hydrometers)...

For anyone else's benefit (I guess this is a geek only zone now?) … I'm not trying to emulate a hydrometer messing with pycnometers. Hydrometers emulate what a pycnometer can do! Hydrometers are more convenient for most people (not me) and hide away concerns about "reference densities". But as a res...

The issue I've had with refractometers is not the brix scale or even the effect of alcohol, but how massively they have been affected by wort colour. They're fine with most pale worts of course, but it seems like a different correction factor is needed for almost every shade once getting to things ...
