Here I will discuss how I go about scratch building the cab and adding detail to the inside of the cab. I will deal with the cab first of all and when I am happy with the results I will commence with the backhead. In the attached image A, C, and D were cut out on the pantograph machine and B was cut out on the cnc machine. The rivet holes on D were done by hand and the ones on B were machined on the cnc machine. The rivets will consist of scale rivets from ScaleHardware of America that have a .5
Having purchased a pantograph machine over a year ago I was eager to put it to good use on my Cambrian project. I decided to have the master laser cut in acrylic sheet at a ratio of 4:1. I could have cut out the shape by hand using another material but why make work for yourself when you can easily draw the artwork on the computer. When the artwork is finished it is simply sent to the laser cutter for cutting. The image I have posted shows three tender chassis sides machined using two different
As I mentioned in my introduction regarding 3D printing, I decided to produce my own axle boxes as there were none available that resembled the Cambrian one. I was fortunately able to obtain some good photos of the loco and a works drawing which helped me design the axle box. After creating a 3D model it was then saved out as a stl file for 3D printing. I am awaiting delivery from Shapeways where I have sent my stl file for printing using their frosted extreme detail material. The axle boxes wil
I have started scratch building a Sharp Stewart Cambrian 440 which will be in EM gauge and hopefully powered by a portescap motor on a split chassis. The choice of material is nickel silver (NS103-half-hard) as I believe this is superior to brass when it comes to scratch building. Tufnol rod will be used to make top hat bearings to isolate the driving axle from the motor and pcb board for the split chassis. 3D printing technology will play a part in the construction of the loco and will be emplo
