This all started when I started trying to build a PDK Kit for a J17 to P4 gauge. I rapidly had to abandon the instructions and many of the parts because the compromises made were just too much for me. Before long I was replacing large parts of the kit and designing replacements both in etch metal and with 3D prints. This lead to a conversation with Brassmasters about the possibility of making my design available as a kit. Modelling the firebox/boiler/smokebox in 3D case was quite a learning experience as the model was probably an order of magnitude more complex than anything I'd done before. I decided that I wanted to try and use the etch metal to give the appropriate strength and thinness to the foot plate and cab sides. I originally 3D printed the entire tender in one go but decided quite earlier on to instead etch the chassis, a decision which I was very happy with.
If you want to purchase one take a look at the Brassmasters' website https://www.brassmasters.co.uk/ger_j17.htm
ExpoEM was proceeded by a large amount of 3D printing to provide some kits 'for stock' and putting the final touches to the instructions. The show itself was very enjoyable with a good selection of layouts and excellent trade. I can't think of anything else which would make a trip to Bracknell so worthwhile.
In the best tradition of 'no peace for the wicked' I'm now working on an extra etch for the cab front to allow an alternative 3D print to make a round-boilered J16 together with more parts for a Coronation.
