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!




Next up: A GCR 11B.
