I've been an admirer and a member of this site for sometime without ever contributing anything, apart from a few comments on items which have been of particular interest to me, so I thought it was about time I started a thread about my particular interest, which is the Hull & Barnsley Railway.
Before, I reveal what I'm currently working on, I'll set the scene by giving a few details about a layout I'm in the process of building, which is a Scale7 Hull and Barnsley themed layout rejoicing in the name of "Staircliffe Exchange Sidings". It's a purely fictitious location somewhere in the Barnsley area , circa 1908 and represents some exchange sidings for the interchange of traffic between the Hull & Barnsley and other local railways. In the scheme of things there are larger 'off layout' sidings with a direct connection into the Great Central's 'Woodhead' route. As work progresses more will be revealed!
At the Telford GOG gathering last September on the Trustees an Executors stand I purchased a scratch built FS model of a H&BR Stirling F2 0-6-2T locomotive with the intention of converting it to run on Scale7 track. Comparison with drawings and known dimensions revealed it to be an accurate model of the real thing. At this point I decided that rather than convert the existing wheeled frames I would build new ones.
Working with what information I had and a number of good photographs, I drew up on my CAD system a new set of frames, which more closely followed those of the original design and profile, including joggled rear frames to incorporate a radial axle for the rear pony truck. Happy that the frames were as close a representation of the original that I could achieve, I transferred the dimensions to 0.028" nickel silver sheet and then used various radius gauges to replicate what the drawing required. Satisfied with things so far, I sweated a nickel silver blank to the one I had marked out. The two blanks were then attached to the wooden platen on my milling machine and as far as was possible were milled to the correct profile. A fair amount of work with needle files gave me a pair of frames I was happy with.
Spacers, designed on the CAD system were produced using the same methods employed in making the frames.
The joggle at the rear of the frames was achieved simultaneously in both frames by placing them mirror fashion in my 'Hold & Fold', ensuring that that they were both square to the bending edge, taking a deep breath, and bending them to the required angles.
The accompanying pictures show the frames in their present state fully assembled. As work progresses I'll post more pictures.
