Why don’t you just copy the Mazda
timing ring and cut a few extra holes in it to lighten it up. You could cut it
to look like a miniature auto trans flex plate. Also, don’t forget about
metal fatigue. Aluminum is much more susceptible to that.

involved a magnet, or at least a dominant spike of metal passing the pickup.
Yes, this is
possible. I have operated a pip sensor with a steel set screw in an aluminum
disk before. However, a steel "ring gear" would be a better bet. You
know it will work if you made it look like the stock timing disk. It would be
less likely to vibrate out of position unnoticed.
