Hi all,
Needing to consider aluminium solder I looked it up and there seems to be something new around. It's only 300 degree C solder and fluxless.
Cheapish too. I've ordered some and will report back. "Film...at 11" as they say.

I'm thinking it could be ideal for the stern corners of the Hornet II model. My alternative was to make a press tool, which I didn't really want to get involved in. Apparently with this stuff you can even use a big soldering iron for smaller bits. The beauty of 300 C is there's no risk of melting the object being soldered and they claim there's no difference in hardness, elasticity, brittleness, etc, so clean up is easy, all objections to the original ally solder. I once used the original with complete success, then next time, complete failure. Maybe this new stuff will be the answer to a maiden's prayer, as my Dad would have said.

Cheers,
Martin
