Thanks Terry!
Here are the pictures I promised in the last post. Below is the original “horseshoe magnet”, and next to it the unpainted new version. Those early magnetos actually have two magnets mounted side by side. Since I thought it would work better to bend one piece rather than two (and hope they come out the same), and I didn't think that trying to make a cut after bending would work out well, I tried to simulate the gap between with a scribed line and and different shade of black to suggest the shadow in the gap. The bending worked well, the visual trickery not so much. Then it occurred to me that, since the back of the part is basically invisible, I could make a cut up the middle of the blank only part way, then do the bending. This worked well and looks much more convincing.
Here's the back side, showing how the cut stops short. I used aviation snips to make the cut. A razor saw would also work, but the blade in mine is toast. Needs to be but hasn't yet been replaced.
Painted and in place.
This last photo shows the two ali disks, behind each of the smaller gears, which will carry a Hall effect magnet for the ignition system.
Also shown is the “water pump”, which is due to get a bit more work for appearances sake. The mounting bar for it functions also to limit the movement of the camshaft in that direction. The cam bearing at that end of the crankcase is flanged, but the flange is on the outside so that it can be pulled out, allowing for the removal of the entire camshaft. Originally I had thought to fix that bearing in place with a set screw, but using the mounting bar serves the same purpose more simply. I also need to order some shorter set screws for the gears!
