Genghis's 7mm Workbench

Just a thought. My train spotting days in the 1940-50 period, I never thought green suited the A4s especially on the Queen of Scots and tees Tyne Pullman’s. Blue seemed my preferred choice. Curiously I thought blue GWR kings ghastly, perhaps it was the subtlety of green…….but it was a long time ago!!!!!!! Hornsey bank and a bicycle are just a memory.

Hi John , Hornsey bank , was that near the Hogsback bridge at Haringay ?

The location was just below ally pally. A public footpath on the embankment allowed observation of railway activity from above. The position and height was approx. level with the rather large signal gantry. There was a branch line heading westwards where a GWR 1500 would appear with a few waggons. The signal gantry gave early warning of loco movements, a chime whistle the group would utter “streak” in unison. From memory the track plan was between 15 to 20 tracks wide thus there was a lot going on. Much better than Finsbury park where one had to squeeze behind the tennis courts to be a good view of the railway.
Not been there for 70 plus years……..probably changed a bit since then?

Ahh , I'm not familiar with your tennis court. The hogsback was at Haringay ( after Finsbury park heading north ) and before Hornsey . I believe the marshalling yards were called Ferme park and they had a public footpath above them where you could sit and watch . It ran from the end of the hogsback and finished at the head of a dead end street .

I am currently doing three jobs at once: an LNER F1, a Fowler 4P tank and the test build of the new O4/8 kit. Busy, busy busy............

If I remember correctly, the M52 driving trailer was Adrians first coach kit. Back in the day, my ready-built LNWR M49 was very popular in 4mm scale and could be worth trying in 7mm as a kit.

I used to enjoy meeting Adrian at the farm discussing my next coach, which we did for about 16 years. Ever conscious that many hours spent on a PC were not good for him, I used to keep requests for detail as simple as possible. Then one day, he phoned to say he could do me the LNWR non-corridor coach that I wanted, but he preferred to do the design work himself. What turned up were coach sides with far more detail than I would dared have asked him to produce on CAD and so from then on I left him to it haha. :drool:

Regrettably I didn’t get chance to complete the upper works. Still have lamp irons, coal rails, backhead and handrails to complete. I also have to scratch the mechanical GCR push-pull control that the loco sported till the end.

There will be a short hiatus as I am off to Taipei for a couple of days.

The F1 went on the back burner for a while. I spent a long time cleaning up the crossheads and slidebars only to find that they are the wrong type. Another set has been supplied by Laurie but while waiting for these I got on with the next job: Patriot ‘Royal Signals’ seen here waiting the paint shop.

Boiler bands, return cranks and deflectors to be fitted by Paul Moore, the painter.

At long last I have finished the F1. A couple of firsts for me: first build in S7 and first with working inside valve gear. I think that if you are going to have a go at working inside valve gear, Joy gear may not be the best place to start.............

The original kit was designed by Adrian Rowland, so you know it is going to go together as it should. Unfortunately I had to throw away nearly all of the frames. Well not true, I retained the sides and some of the spacers. The frames are wider in in the middle than the ends. I found I could use the wider middle spacers at the ends and cut new ones for the centre section. The kit was designed as a 2-4-2 with simple conventional pony trucks and drive to the leading axle. The requirement for working valve gear meant that the drive had to be moved to the rear axle. So no place for a pivot for the pony trucks so it has been built as a pseudo 0-8-0. There is plenty of lateral throw on the trailing wheels so it should be able to negotiate S7 curves. The driven axle is fixed while Slaters Hornblocks are used elsewhere.

I had spent ages getting the original crossheads and slidebars sliding nicely, only to realise when I checked the GA that the wrong type had been bought. Laurie supplied the correct type. If I hadn't have had a GA I don't think I could ever have made the valve gear work as I would not have had any dimensions. It wasn't a 5 minute task but it does run smoothly. If I can work out how to get a video in this post I'll provide evidence.

The particular loco requested by the customer retained GC mechanical push pull gear so I had to scratch a representation of this.

I am happy with the end result which will now go to Paul Moore for painting with strict instructions not to do anything to the valve gear!

The F1 looks very nice indeed. I'm impressed with the working Joy valve gear. As you say, not the easiest gear to build. Although there are no eccentrics (the main benefit of this type of gear, as I understand), it makes up for it with the curved reversing guides and multiplicity of rods and levers.
I'm hoping to install working Joy gear in my P4 L&Y Class 27 but have taken the easy road of contracting production of the curved guides and crankshaft to a professional modeller.
