Will be interested to see who you go Roger, have tried to varying degrees of success to solder to Aluminium, if I remember the process it goes like this,
clean surface with non ferrous brush and coat the surface with oil to provide and air exclusion layer, clean again while the oil is in place (the hard part) to get a freshly cleaned surface and exclude the air so it does not immediately oxidize, apply heat to the aluminium via a soldering iron tip through the oil (not gas) and proceed to tin the surface of the Aluminium with standard 60/40 solder.
While I am working on my solder to stainless project on a 50 MHz yagi I am rebuilding (it has dissimilar metal contacts in the feed arrangement that is causing me grief), will see if I can revive my solder to Aluminium skills and if it works out will post a photo
