Hello David , This are the best shots? . I had a look at their website. Very impressive. When I watch your engine it is not shaking like mine. Maybe I will have a look at my springs. Regards Michael Hi Michael As you can see, mine is a MoK too. When starting mine does sway from side to side due to the leverage from the pistons but settles down after about 100 feet or so. After that she just runs true. And, when I open the regulator fully en route to accelerate quickly she stays as steady as a rock. I find the best plan is start slowly and gently I supposed instilled into me by the Princess of Wales I run as well. I very, very rarely have a slip with the PoW and only then when mucking around. I will try to find a clip of her starting at Gilling. If you watch the average(?) driver of a miniature loco, they open the regulator fully and away it goes sounding a bit like an outboard engine, the acceleration would please Jeremy Clarkson whereas prototype locos start quite slowly with low acceleration and chuff chuff away, so that is what I try to do and the swaying is minimal. Have a look at this for inspiration! bracknellrailwaysociety.co.uk/index.php/a4-class-bittern-stops-at-bracknell-station/Cheers Daviud

I love these ground level tracks, it's so much more authentic, as are the carriages. What a cracking setup! I invite you to visit me and bring your loco for testing on our track ( www.asafegi.com/modelisme/tren-tripulat/ ) during your next vacation. Great climate and many things to do in the region, which is among of the most visited places in the world.

I think I've got at least three more years on my build to go!

Further to my diatribe on starting gently I have managed to extract this little snippet from a rather long video. You need to go to minute 2 to find the bit to look at. I had been held this this signal for about two minutes then it was pulled off. You will see that as I go over the bridge that has aluminum rail I get a little too greedy on the regulator and generate a slip. By putting the reg back to where it was I can continue up the hill to the next signal which btw stopped me so there was no hurry at all. So here is the clip, just a little ego trip for me!!! www.youtube.com/watch?v=gw-Qyj3AWGMCheers David Now back to making a new whistle valve for the Princess, by far my favourite engine!!

David, your PoW is a real princess. If there is a moment you shouldn't don't like her anymore I would know a good place for her. Yes, your starting is like the real one. I like it. Did you build in an axle pump? What drawings you had for your midland compound? Cheers Michael

i agree with Michael... she's a real jem.... I would love to build a single...for me it would have to be the stirling... not because they are any better than the spinner.. it's just a preference of railway company that decides it for me...GNR or LNER every time....mind you I can see myself building a crimson loco just as easily as a green one....

Pete, On YouTube I found some videos from a stirling single in 7.25". Do you know who has drawings and castings for this loco? Michael

sorry Dave no I don't....that would be a lovely loco to build though... i seen to recall a 7 1/4 stirling being mentioned before in another thread.. alas i can't remember where or when... Pete

Singles, aluminium rail and gradients do not mix. years ago when I was a member of UDMES there was a member with a Stirling single, his dream loco. Urmston track is aluminium with a couple of long uphill sections, the poor Stirling just slipped no matter how gentle he was

Cheers D PS She is my precious, you will never get your hands on her, other than as a guest at our singles day, then you can trickle her fancy all you like!

Pete Dear GG I started with the Stirling but was drawn to the Spinner as she was a Johnson and Martin Evans did a build series. So I do not really know whot what to do. I love the Compound and the 4Fs but love Gresley so I am a bit if a tart, just like the latest boy on the block. And of course, arrived in the UK in Yorkshire IN 1977 and discovered the A class L & Y so I am trying to build one. I have one in O Guage but in 5" wow, my wife bought me the castings!! Do you do therapy??? try www.sfmes.co.uk/ydrRoot/newsLetters/minutes/201503.pdfThis may explain a bit. I think sleep beckons, thankfully, at last we raised £305 for the air ambulamce today Nite nite D

Michael Hi , Martin Evans described the 2-2-2 version for both 5" and 7-1/4 gauge though sadly he made a complete mess of both . I have dim memory that both Clarkson and Greenly had designs for the 4-2-2 version in 7-1/4 gauge . Some of their drawings may still exist . The 4-2-2 version would be a simple engine to design and build from scratch in 7-1/4 gauge in any case and the full size drawings are available . The 4-2-2 version seems to have been a popular engine to build for apprentice training in years gone by . Students at Regent Street Polytechnic and one of the big locomotive works both built examples in very big model gauges - guess from pictures 15" or 18" gauge . Both Greenly and Martin Evans attended Regent Street Polytechnic at different times I think. There were pictures of a delightful 3-1/2" gauge model of the 4-2-2 on the cover of a 70's ME . MichaelW

michael will know a lot more than me about this but in theory a 'spinner' has a lot going for it than may at first appear. if properly sprung (not often done in miniature but something i always do) a single wheeler has an awful lot to recommend itself. after City of Truro's famous run in May 1904, the train was taken over by single wheeler Duke of Connaught from bristol to paddington and put up as impressive a performance as the City. i am quite a fan of the LBSC Stroudley single wheelers which lasted until around 1907 when Marsh prematurely scrapped them and his own replacement locos werent up to the job!
why a single wheeler has the edge on some bigger locos is a very interesting subject, and as stated before on this forum a GNR single wheeler in 5"g won IMLEC a few years ago against all the odds!
cheers, julian

Aluminium rail looks to be the biggest problem, though I'd hazard a guess at springing not correct too.

Did you build in an axle pump? What drawings you had for your midland compound? Cheers Michael To answer your questions properly!! Martin Evans drawings, exactly as described in the ME, two injectors only, no pump, hydrostatic lub. I bought it part built around 1982-ish. Did some work, then a divorce caused it to be hidden away from view for about eight years with a friend who did a lot of work for me. I recovered her (was tearfully reunited!) around 1990 and had to buy a boiler (Bushell). Have remade the main crank twice, once because an expert showed me how and his work lasted about ten minutes, he could not drill a hole straight (through the webs) I have remade the valve gear in total and loved her, cursed her, but she still runs just a she should. She could do with a bit of tarting up of course. Will probabaly take her apart completly one day and do a major overhaul. If you are still following these threads, you will have to wait until I die to get her as no-one in my family is interested. Cheers and toot toot, David

Hello David, I hope you have many many years left here on earth to have fun with your locos. My MoK has the pump build in but not connected. I need to find out what my both injectors likes at best. The left one was working ok, but at the end of steaming he did not liked to work at full pressure. The right one only worked short after firing up. Then I needed to cool him to make him work. Either there is the steam valve leaking a little bit, or the clack valve is not OK. It doesn't help to let the water flow through the injector. The injector was hot all the time.

Thank you for this link, I saw it also and the driver seemed to be a little bit disappointed. He has real problems to keep the engine going.
