And the Joy valve gear also suggests LBSC (the original was stephensons) so I can go with John's suggestion

Kennions can supply plans off the shelf for the 3 1/2" gauge Miss ten to eight, I bought a set last year when a chassis I started when I was 16 or 17 turned up in a box ,oiled up and put there when I married and left home in 1979! Bit of a shock as I'm an OAP now! Looks like you have a good start to a nice little locomotive there, plenty of help available from the G1 association, they do some good publications that may help, you could probably adopt the " Project " type boiler quite easily for that engine.

Hi Mick, back in the nineteen seventies Don Young designed a 4F loco in 3 1/2 gauge and that used Joy valve gear which might help. It looks like you already have the weigh shaft, however you would need a reverser in the cab and corresponding reach rod. I think I may still have the original article and could possibly email you the appropriate pages if you are interested.

Hi Mick H, I have spares of these three volumes that John has mentioned, they are not all it the best condition, but all the information is readable, and volume 82 was half heartedly bound. You can have them for the price of postage, or you could collect them in person, just PM me if you are interested.

Regards Nick.

Hi Mick

If it's any help there should be some pics of my 3 1/2" Miss Ten to Eight chassis as it is now cleaned up ans a bit more work done on it to get it to a rolling chassis, tried to show the layout of the valve gear and the general shape of the frames. But do ignore the back of the frame from the blue line backwards, as I've grafted in an extra bit to make it more like the full size and to give room for a sight feed lubricator oil tank. As an aside the parts had been dipped and sprayed in Shell Ensis fluid when packed and it had perfectly protected it in an outside wooden potting shed for over 40 years, an absolute pig to get off solved by getting it dipped in an engine builders hot tank. Worst bit was cleaning up the brass tender parts for soldering together, they had not been protected.

Thanks Mick, I have re-made some of it, teenage me was not quite as fussy as old man me!

I couldn't afford the castings at the time, so the hornblocks were steel and looked quite clunky, so I replaced them with castings, and bought the wheel castings from Kennions, but most of it is original. The cylinder block is cast iron made from the overarm of a Cincinnati mill that was being scrapped. At one point I may remake that in gunmetal as there is no room for cylinder drains as the bogie is really close. I may never finish it, too many projects, but it looks better on the shelf than a pile of bits, and as I look at the parts I remember the people I worked with who trained me and oversaw the work, I learned a lot. After all these years I clearly remember the conversation we had as I was putting the crank axle together, it was about the future of engineering in Britain – and they were right!
