Hi Regards the pusher prop question.I built a Supermarine Walrus a few years ago which has the engine mounted as a "pusher" and bought a left-hand prop for it.Saves all the mcking about with props fitted "backwards"which do not give enough power .

Ali.cans can be annealed easily by rubbing hard soap on one side and heating the other side with flame(ie.over the gas hob on the cooker) when the soap turns a dark colour quench the ali.in water and you will find that you can work the material easily
