First lengths of nickle silver wire, .33mm , were cut to size. Thin card was cut to rough size to pass through the upright handrails. The wire was held in place and a very small amount of flux was applied to the joint. Soldering iron tinned with a small amount of solder and quickly applied to the joint. The top picture shows the flux residue after soldering. I won't be bold enough to say that every one worked first time, it didn't.Some of the handrails are not exactly parallel to the sides wich made lining up tricky. However, after a couple of tries each van now has its handrails complete. Also there is no damage to the sides of the van.
Next job is to thoroughly clean the bodies of flux and then they are ready for the paintshop.
