You're absolutely smashing it Mike - The reverser is a jewel and the platework so crisp - you'll be steaming in no time :-) All the best - ~ Phil Thank you Phil, Unfortunately the plate work doesn't look as clever when viewed from underneath.

I have at last reached the stage where I can run the chassis on compressed air. I first connected the airline as shown in the pics and nothing happened. Being a Webb compound, it needs the HP exhaust by-pass valve opening to start (its the little button at the front l/h operated by a push/pull rod from the cab). I did this and the HP engine clattered into life. With the HP engine running I shut the valve expecting the LP engine to start. Being a Webb compound, It wouldn't until I revolved the front driving wheels by hand to a favorable starting position.ie just after front or back dead centre. In this position, both engines ran. It doesn't run very smoothly because the large single cylinder engine runs completely out of phase with the little twin hp engine. Although this should improve with the wheels on the rails and with a load behind it. Best of all, because its one of Mr Webbs finest, I am able to make the 2 sets of driving wheels rotate in opposite directions. So, im very satisfied with the results. I appear to have succeeded in reproducing and incorporating in my model, all 4 of this engines worst and famously, least useful features.

I thought that given the nature of the beast, you would expect your problems to be 'compounded'! Good progress though, and better than mine! John

There are not many locos I would go out of my way to see but I would to see this one running.
Keep up the good work

Great work Mike, and what a lovely loco to model. At the risk of alienating 80% of modellers, there is something very special about these early locomotives. Any chance of seeing some MP4 videos of your engine on compressed air? Ed

Count me in the 20% not alienated Ed. I have dreams of a Johnson Midland 4-4-0, maybe 1757, "Beatrice" lurking in the back of my mind. Jim

Hi Mike,
My congratulations also and praise! I remember reading Rodney Weaver's stuff on the Webb Compounds, and LBSC's description of his 'Jeannie Deans'. Absolutely wonderful for you attempt anything like this.
Perhaps for the uninformed you could explain why the LP cylinder can turn one set of driving wheels in the opposite direction to the other driving wheels driven by the HP cylinders?!
Cheers, Julian

Cheers, Julian . Thanks for the kind comments. The reason one set of driving wheels can turn in the opposite direction to the other is that: A) they are not coupled. The loco looks like a 2-4-0 configuration but is actually a 2-2-2-0. B) While the rear drivers are worked by Joy valve gear controlled by the screw reverser, the front pair of drivers are loose (or slip) eccentric and unless care is taken will revolve whichever direction the eccentric happens to have been running in last. Unfortunately I have no idea how to post a video. I will ask my son.

Not alienated here either! This era for me represents 'proper locos'! I'd love to see a video of her running also

It will be a while until it runs again. I've been fitting the boiler the last few days. It's a fiddly process that involves removing all the front suspension components and the radial axle, the running boards. Then trying to shoehorn everything into the smoke box and wiggle it into place and then trying to get an air tight seal around the base of the smoke box. I have had to make up a couple of long Allen keys to get down the chimney to reach awkward screws in the bottom of the smokebox. It's a bit like building a ship in a bottle. As it will eventually run with a displacement lubricator I won't be able to get oil into the engines to run it on air again. So the next run will be on steam.

Hi Mike – You’ve been awfully busy to get the loco and tender up to that standard, superbly done! If I may – given your frustrating experience with the plates (and if you have no other alternatives) I’d like to offer my help and arrange to have these made on your behalf @ cost price. I’ve quite some experience in designing + producing these kind of parts through Mike Jack in NZ. ( 44767 of BR Std 3MT fame on this forum ). Feel free to send me an email offline at philip.monsbourgh -(at)- gmail.com if you’d like to pursue it.
Best regards, Philip

I do appreciate it very much. Last week I contacted Diane Carney Nameplates and she came straight back with a quote. So hopefully I am alright now thank you. If I still have trouble I will be in touch. Mike

Absolutely fabulous, I have a 3 1/2" Jeannie Deans, which I bought as a non-runner, so I know a lot of the problems, particularly inside the Smokebox, I'm painting at the moment, the lining is murder, runs very quietly in action, hardly any blast. I use Guilplates in Guilford for nameplates and cab numbers etc very reasonable price and good quality,I've only just spotted this topic so I've got them all to read, once again, fabulous workmanship.

I find, as a builder, progress seems painfully slow. But when you look at updates one year apart one sees just how much is achieved; little by little. Yours is a beautifully made machine. Always look forward to the next photos...!

Decided to bite the bullet and start the horrible job of painting the tender. So made a start with the wheels and chassis parts this weekend. Because its made from wood held together with lots of little steel brackets it needed to be completely dismantled to the last nut and bolt to paint. Incidentally, when I built the tender I decided to incorporate needle rollers into the wheels like this:- Not very prototypical I concede: The axle is 10mm dia commercially available hardened and ground shaft. the "cannon" type axle tube is brass (bronze would have been better) and the ends protrude a bit to provide the thrust faces.
