That's probably old enough, and 9/16 W is just over an inch across the flats, them's big nuts ! springy

Unless the boat has significant age I would expect to find metric threads on the cap bolts. springy

I'm not convinced that mixing a diaphragm pressure pump and a centrifugal pump is going to work without at least some isolation, though that could simply be an "L" port valve joining the two outlets, (the handle of which could operate a switch controlling which pump ran), but don't forget to consider the size of the inlet - that pump has a 22mm inlet, if the pipe from your tank is 15mm it will restrict the flow, less of a problem if the pump is close to the tank but could be significant if the pump is some distance from the tank, any filters or valves in the line may also restrict flow. springy

A few years ago several of the balance beams on Walsall locks were cut off - turned out to be two guys with an old cross cut saw trying to see how quick they could cut through - some sort of fitness thing. springy

AIUI Claytons main cargoes were crude tar from a variety of midlands gas works to the tar distilleries; and lubricating oil or fuel oil from Stanlow to the shell depot in Oldbury. There were less frequent cargoes of "gas water" also known as ammoniacal liquor from the various gas works - this was water used to scrub the gas, removing ammonia, which resulted in a product which could be used as a high nitrogen fertiliser and probably a variety of chemical processes. I believe there were also bulk cargoes of the tar distilleries products - particularly creosote to the London area both for the railway companies and GPO Telephone poles. springy

I found this earlier today :- springy

The possibility of the bubble tester being faulty has been mentioned a couple of times, I've been considering the potential "failure modes" - did you check the fittings on the bubble tester itself with leak detector ? Could it be a genuinely faulty bubble tester which only leaks (up the button stem ?) when the button is held down ? springy

Grade 1 cylinders are tested to 3.65 bar, working pressure 2.5 bar (25m head), grade 2 - 2.2 bar test 1.5 working, grade 3 - standard domestic - 1.45 test 1.0 working. IIRC the one I purchased some years ago from a chandlery was 4.5 bar test, 3.5 bar working (still functioning perfectly). Apparently for cylinders over grade 1 pressures both ends of the cylinder have to be convex, with a foot ring on the bottom, whereas domestic graded cylinders normally have a concave bottom. springy

I had a vaguely similar problem a few years ago with my 1.8, intermittently needing bleeding, after checking all unions, filters etc. I eventually tracked it down to a crack in the lift pump body. There was no sign of fuel leaking from the lift pump but it was managing to suck air in. springy

And Chimney Collars if fitted springy

Fuel supply, most likely -check filter(s), pickup pipe, lift pump. Unlikely, but a friend had an LPWS3 which IIRC had similar symptoms, which turned out to be the return spring on the pump elements - 2 of the 3 were broken. springy

will the revs pick up in neutral - if so check prop isn't fouled, if not - broken/disconnected throttle cable could be a wide variety of things but that's where i'd start springy

If you can not get the inner race off in situ you MAY be able to remove the rudder in the water. Fit an eyebolt into the bolthole used to retain the swan neck, attach a length of rope to this. You will need a reasonable depth of water/canal below the rudder, and your other rope still attached to the eye in the rudder blade. Lift the rudder out of the bottom cup and lower below the boat using the rope attached to the eyebolt, retrieve from below the boat using the rope on the rudder blade. Leave the rope in the rudder tube for re-installation. springy

A quick google says capacity 20,000 containers, currently carrying 18,300. Wiki says 20,124 TEU (Twenty foot Equivalent Unit) so presumably forty footers count double. springy

AIS has it as stationary at the moment (happy nomad beat me to it), but there's a quite a stream entering from the med, and the first of the backlog held in the lake is just popping out into the Red Sea. springy

AIS has it well on the way, without the flotilla of tugs and making 9 knots https://www.vesselfinder.com/?imo=9811000 springy

Yes they look like standard 70's inertia solenoids, I think however they are insulated return ("Marine") units rather than standard units, which would just have one spade terminal and use the mounting bracket as the return, be aware that they are also available with an auxiliary contact (for a "ballasted" ignition system as seen on some 70's ford cars) which will LOOK like the units you need but the energise circuit is between one spade and the mounting bracket, the second spade (which may be smaller) is connected to the main feed when the solenoid is energised. The wiring certainly looks like they are paired in the positive and negative main leads - possibly a way of providing "insulated return" as Tony suggested earlier, and nothing to do with charge splitting. springy

And there's this a bit further down in the briefing :- "The backflow prevention devices will considerably reduce the rate at which water is dispensed from the taps. Please allow additional time to fill containers and bulk water holding tanks. Please also expect an increase in the amount of waiting time if the facilities are already in use." (my bold) springy

I have a similar setup using an "L Port" valve, many suppliers but usually 1/2 inch BSP-F so you will need fittings to suit, https://www.allvalves.co.uk/valve-actuator/1-2-brass-ball-valve-3-way-l-port-rb-bsp-lever-op https://www.directwatertanks.co.uk/1-2-bsp-female-3-way-l-port-ball-valve and in stainless somewhat cheaper than RS https://www.swiss-fittings.com/3-way-ball-valve-t-port-a-730-tt-1595?___store=en&gclid=EAIaIQobChMI9sK89Ym37wIVO4BQBh31bQiAEAQYByABEgJ4hPD_BwE avoid "Reduced Bore" valves. springy

This page https://en.wikipedia.org/wiki/Propane,_butane,_and_LPG_container_valve_connections has a table which lists 11 different sized "Quick Couplings" from 16 mm to 35 mm. including 20, 21, 21.7 and 22 mm ! It also has three LH-POL standards - two appear identical and the third (UK) is functionally compatible but specified as 5/8 - 14 TPI BSP thread form rather than NGO (National Gas Outlet - american NPT family thread). In theory an american spec regulator POL would be very slightly looser in a UK valve but within thread tolerances and the seal is on the cone seat not the thread. Also "patio gas" is propane but in bottles with a company specific Quick Coupling. springy

AIUI the industry standard for Propane (vapour take off) is known as a "Left Hand POL" - POL = Prest-O-Lite, the original manufacturers of the valves. This fitting is also used on most other vapour-take-off fuel gases such as acetylene and hydrogen. Non fuel gases supplied in bottles have the same fitting but with a right hand thread - oxygen, nitrogen, argon mixtures for welding etc. This is a cone seat fitting and relies on a metal to metal joint, unlike what was the standard "domestic" fitting on butane bottles which relied on a male thread on the bottle and a rubber washer. This was standard across bottled gases until the advent of snap lock fittings when the different companies realised that by using a snap fitting regulator of an individual size for that company they could more effectively "tie in" their customers (cynic hat on). I suspect that the potential leaks from a butane regulator fitted with the washer missing also prompted the change when mobile gas heaters (calor super ser etc) became common. This practice seems to continue to spread - many mig welding gases now come with company specific fittings, though arguably safer - the fitting is either on or not - it can not be inadequately tightened. springy

The louis ranger is designed to burn wood, not coal as usually used in a back cabin; it is of welded steel with (i suspect) no insulation on the back and sides. Unlike the typical back cabin stove which is usually a mixture of Cast Iron, a refractory brick lined firebox, and on the back and sides a layer of insulation under a sheet metal cover (why most back cabin stoves are much closer to their surroundings than the regulations would require for a stove with an un-insulated body). I was going to say its the wrong hand, but for £30 extra they will make one the opposite hand. springy

That's a tidal barrage to prevent salt water going to far inland, rather than a flash lock to maintain a navigable depth. And its utter mayhem at opening time. springy
