Water valves are on / above the injectors, one on each side, operated by the sloped rods emerging from the Firefox cladding. Inside the cab they are simply bent TO THE LEFT (both sides) at 90 degrees like damper handled commonly are. One seat only for the driver on the Bressingham loco Can't find a slacking pipe...

Here's the mystery of the steam reverser..... although this is from a larger Garrett

Phil Parker has taken some very useful photos on his Flickr blog, which includes the cab showing the various levers. Meanwhile here's the plan and elevation. That lever looks as if it's the water feed to the injectors ( which should be two separate levers...?) It's all a bit confusing on the drawing.

Simon, Here's the view of the RH side of cab.... The highlighted bits are I think the reversing linkage to the steam reverser, but what the lever is like.....

Simon, don't shoot the messenger, but I've just noticed you've got your cab beading fitted the wrong way round - the handrails are in-board of the cab sides, not out board. I made the same mistake, due to incorrect kit information if I recall, and had to un-solder them and refit them on the opposite sides...... So sorry!

I think I would be inclined to go for a maximum of 150rpm, or even 100rpm, given your using 1:1 bevel gears as final drive. 15mph equates to approximately 130rpm at the wheels by my reckoning

Hi Jerry, These are the bevel gears I tend to use when I've got room.... https://www.technobotsonline.com/mini-plastic-bevel-gear.html

Purely for informations sake - I have made some embossing tools for sets in 4mm (as well as 7mm) which emboss partial rows. This was probably six minutes worth (of actual embossing) into rolled out modelling clay. After painting, ash or similar powder is brushed over it and into the cracks, being fixed with very dilute PVA.

I was just trying to remember what I did with mine..... Looking it up, it was sprayed black overall, and then red. In the past I've ever used a dark green as an undercoat, which was quite nice! Its all looking lovely and familiar! It's really nice to see some good builds of these things.....

Very very nice!! (When this is all over, we should have a gathering....)

I'm guessing the bottom one is the slew. You can see a sheave on the column above the bottom ram

Lovely to see it move Simon! At the very least it must be reassuring! I used a Loksound on mine, with a Pannier file, with the double-heading option enabled. I didn't worry too much about it as not too many people will remember these particular locos in steam!

Slightly off topic, the stage machinery- in particular stage lifts of London's Theatres were powered from the mains for very many years. If I recall, the Hydraulic lifts in the Opera House were only removed in the early '90s (although long since disconnected..,) We still occasionally use jigger rams for elevators, either vertical or horizontal, although of course now modern high pressure oil type

Couple of others for the list..... Tank lifting eyes Engine steps Narrow Planet did me some correct work plates, incidentally! Looking good!

Nice to see it running Simon! Just four sets of valve gear now......

Looking good - on a vehicle like that, have you thought about using a linear actuator to steer, rather than a servo - or isn't there sufficient room?

...Absolutely!

Definitely Saturated boiler, not Superheated. Also, I believe this valve was fitted from new, as one of the works grey photos show it.

2mm couplings here.... the 1mm type are identical, just with teeny magnets in the same place!

The magnetic strength does very much affect the performance/attributes, insofar as a magnet that is too powerful makes for unrealistic coupling, and one not powerful enough won't pull the train - so therefore experimentation was necessary. These couplings have two magnets per fitting - one facing North and the other facing South - always the same way. This means that you can put the stock on any way round and it will always couple. I think I will use the more powerful 2mm dia magnet couplings for stock that I intend to run in a fixed rake - I've not quite made up my mind! You certainly can go for a single magnet - but then the loco and stock must always face the same way........ There's a possibility I could put this stuff up on Shapeways or Thingiverse if people wanted it - although I've never used these companies, do I don't know how it works. PLA is certainly a good material for the Scotch mechanism, and it's nice and strong for the couplings, though it lacks resolution, so a different material might be better for them. The Scotch blade is proportioned for narrow gauge or 4mm standard gauge, but it would be very easy to substitute an 0 gauge standard gauge one.

Here's the Bressingham jobbie - sorry - the photo was taken mid '80s. The pipe in question is on;y about 12mm OD max, and is cleated next to the boiler band, dropping to the back of the frame in front of the boiler feedwater pipe. it may be the one that then runs forward along the centreline, entering the smokebox saddle

I agree..... although there is certainly a valve shown on one of the locos on that fitting. I'm struggling to think what else it could be round there.....

I'd forgotton this.... this is the business end..... a Scotch

To date (about ten years) I've not had any problems with Deltang stuff at exhibition (even including Warley!), although I do recall reading of some other 2.4Ghz platforms having issues.
