First picture showing the build so far. Brake blocks with their hangers suspended from even more hangers (?). Not sure what they would be called
I wasn't sure how to fix the springs in place. Normally there would be pins fitted into the backs of the springs which would be fitted and glued into holes in the W irons. I have done this on whitemetal springs but, I thought that I may break too many twist drills drilling into the laminates of the springs. I was thinking about this problem while in the shower and the idea came to me to solder the springs to the W irons. Each spring/W iron was placed and clamped into position and then soldered. With the first attempt, the heat travelled up the screws melting them very slightly into the styrene which meant that on disassembly, I had to unscrew the screws. I'm sure that you know what I mean. With the others, I clamped tissue, soaked with water, to the W irons which acted as a heat sink. After the soldering, the screws easily pushed out this time.
In the picture, the spring/W iron units are held in place with 14BA machine screws and nuts with the spring hangers simply butting up to the solebars. I'm thinking that on final assembly, I may place a drop of Araldite on the hangers gluing them to the solebars but, they seem to sit okay at the moment without any glue. I'll have to give that one some more thought.
The next job will be to machine up some small tubes which will be silver soldered to the backs of the brake hangers and will eventually take the brake rods.
Second picture showing those whatdoyoucallthems.
Third picture showing a goods brake van in the background. This build will be very similar except it will be painted green instead of grey.
