I am back working on my Silver Eagle. I purchased it back in 2002. After I drilled the hole for the governor shaft and found that it would not turn.:wall:

I contacted Margaret and she sent me a new set of drawings. At this point I found out that that this dimension has been corrected. I corrected my problem by lapping the gears.

But now I am double checking the dimensions on the other governor parts and found that there will be interference between the governor arm and the root diameter of the thimble.

Has anyone encountered this on their build?


What date is on the revised drawings? I am curious if I have the latest set with my castings.
I contacted Margaret and she sent me new drawings. There are many changes to the drawings but unfortunately most of them are not dated. I built one head with the intake and exhaust reversed. This has been fixed in the new drawing.

I have not been able to find the cam timing. There are still a lot of things I do not like about the drawings, but I will work through them in time.

If I had it to do over I would do the Breisch/Peters Associated as my first engine. I have all 4 styles how. I will be doing a production line on these at a later date.
