>How much did tuppers help? Some new challenge for Autumn?

Uh, mechanic work is man's work. We'll make the lemonade and sandwiches and bring them out wearing low cut sundresses.

>Also is there any downside to aluminium (aside price I suppose)?

[Bear] Not really, and price wasn't an issue.

>This aircraft grade alu stuff appears to be extremely tough. Not steel but almost for far less weight. Lots of gun parts are made from it.

[Bear] 6061-t6 and 1018 have nearly the same yield strength but steel is tougher and aluminium will age harden and become brittle after a very long time. It also can fatigue crack and steel is virtually immune to that.

[Bear] It even sounds different which is weird. I know intake manifold design makes Porsche sound the way it does. They actually amplify that intentionally.
