Thanks, Alan. I'm happier with the props now. I altered the shape somewhat and took almost half a millimetre off the width of the broadest part of blades.
I've been thinking for a while how to make the Scarff rings. The first attempt was using plastic bar but I couldn't get the join right and then ruined it when trying to get the ring shape to be perfectly round by taping it to a paintbrush and immersing it in boiling water. The glued joint came apart so it went in the bin!
Then I considered opening out the hole in a washer but that didn't have quite the result I wanted so I called in the heavy artillery.
The result: two brass rings.
With the rings drilled and brass rod soldered in they were placed on the fuselage but not yet fixed in place. I have to make up the small details on the gun mount. I think these are going to be no more than some tiny slivers of plastic just to give the impression of the mount details.
