      I went to the Doncaster Model Engineering show this year on 12 May 2018 and on the Locomotive and Rolling Stock section 39

      There was a very nice model of a 31/2 ins Talyllyn Railway 'Tom Rolt' by a N.Bennett ( Leeds).I wondered if anybody knows what drawings were used or any help would be appreciated.

          Erm… guilty as charged, M'lud. I used Don Young's drawings, but scaled down to suit. I built it purely as a test bed for Gas Producer Combustion and for exhaust systems. I drew out pretty well every part (there was a folder with a lot of them next to the loco) to the correct dimensions using SolidWorks 3D CAD. It was a vital tool for checking on the underfire steam supply and how it would all fit into place (or not) before I cut metal.

          Thank you for your kind words and interest, Nigel.(Great name…)

            but did it work? When do we get a write up?

              Hi Nigel

              Thanks for the reply and info, I read the folder as best I could and it would make a nice write up, perhaps even a series .

              I think that it might be a little beyond my expertise at the moment. SolidWorks is a program that I don't have access to just yet.

              I have always liked Talyllyn loco's and Narrow gauge and I will watch this space with interest.

              Many thanks,

              Nigel!!!!

                I don't know, Duncan – yet – if it works. I'm still screwing up the courage to spoil the nice new paintwork. I did run it briefly with the GPCS system turned on before I dismantled it to paint it, and all I can say is that the fire didn't go out!

                Yes, there'll be an article submitted to ME in due course, but only after I've done some significant comparative tests. Watch this space, as they say. And it won't be today because it's raining, and Cudyll Bach has taken Henry's correspondence course about What to do with your Nice Green Paint in the Rain…
