And Now For Something Completely Different ........
Something completely different indeed. Having been casting about for ideas for something new to astonish the exhibition circuit when it comes out of hibernation, I have eventually decided on something based on the Black Country tramways – a massive system of 3ft 6in tramways that had all but disappeared by 1930. As this is a completely new venture for me I decided that certain things would have to be tried out first to see if the idea was viable and first up was a tram! I was much encouraged here by my friend Trevor who kindly volunteered his skills to develop the chassis. Only trouble here is that he is in very locked down Wales so much discussion was needed via Email and as yet the two halves have yet to meet. More on the chassis later but for now the body.
The closest I have ever come to building a tram body was a Branchlines railcar kit several years ago but in my true pioneering spirit I decided that it couldn’t be that hard! In actual fact it hasn’t been really, just take each bit at a time and try to work out how the original was constructed and be guided by this. As this at the proof of concept stage I decided that if I was going to make mistakes it would be much better if they were small ones, so, having decided between us that the Cradley Bogie would be the first victim I set about building a third of one!
After much thought I started on the sides with the construction owing much to my days of building model aircraft. I was actually quite good at this but awful at flying them and there were only so many times you can take your pride and joy home with you in a bin bag before you become disillusioned! So, I identified the pattern of the ribs, made up a set by making a Nickel Silver sandwich and filling them all in one go. They were then soldered to a plain backing piece over the plan and a thinner outer skin bent to shape and soldered on. The resistance soldering unit was very useful here as was able to press them into shape while the solder hardened.
The window frames were added by soldering brass channel over the ribs and soon a had a basic side – rather boringly I then had to make another! The floor was easy but then the fun started with the partitions. I probably spent far too much time on these but I really wanted to get them right. Nothing really hard, just a lot of fret saw blades gave the ultimate sacrifice. In all I counted 51 separate pieces went into the inner partition.
The BluTack of previous pictures has now been superseded by solder and here we have a basic body end. As I said it is a proof of concept and it has certainly proved that I don’t have the time or patience to make the dozen or so vehicles that would be needed in this way. So, next task is to start working out what I can replace with etched and 3d printed components.
As you may have guessed by the size of my hand this is in 7mm so track will be an interesting 24.5mm but I will tackle that once we have a working chassis and more on that next time.
