Brass roof soldered to whitemetal sides

Finally, some free time to carry on with the Wickham trolley.  

The obvious next job was to fit the roof. This involves soldering brass to whitmetal. When I fitted the handrails, I had to tin them with normal solder before attaching with low-melt. This time I've bought some more 100 degree, to replace the pack I've mislaid, from C&L. 

For a while, the roof has been kicking around but when I come to fit it, it's disappeared. Probably to the same place as the old solder. 

Not to worry, a new rectangle of thin brass was carefully cut out and then curved in the rollers. 

Then a few blobs of Powerflow flux and a bit of soldering iron work and it's in place. I use the normal iron for this although the low temp one will work. If you are quick, the brass acts as enough of a heat sink to avoid damaging the whitemetal bits, and these are big enough to survie a bit of heat. 

While I was at it, the front bumper bar (if this was a Volkswagem we'd call it a "nerf" bar) was made from some nickel silver strip and brass rod. It's done by eye but looks OK to me and is an essential feature of a Wickham.
