Buccaneer,

Your idea of the spring loaded ball and detents in the timer is similar to the early Lockwood timer. It also used that assembly for ground see the Lockwood side view on page 5 and the bottom of the homemade timer on page 6. The Ferro used exposed stops as Tom stated but Lockwood had them hidden underneath as seen on the Homemade timer. Lockwood mounts were like a half round as seen in the side view which allowed for stop clearance and the stationary stop. Or you could do that by milling slots in your mount. My Ferro RBM and inboard engines only have about 25 degrees of traveI, but are designed to run in only one direction. The Lockwood travel about 150 degrees to allow for reversing. They also have insulators in the bottom of the timer base to break the ground at each end of the travel to shut off the engine. It’s hard to see but look at the end of the detents on the homemade timer, the bigger rounds are insulated. Hope this makes since.
