OK, Kitty. <img src="/forums/images/graemlins/lol.gif" alt="" />

Here are the finished cam sprockets for the 3.0L SOHC engine:



Almost all of the work was done on a lathe - first a clean-up of what will become the sprocket mating surface, turning down the flat aluminum stock to fit the sprocket, removing the metal hub on the sprocket, duplicating the hub on the aluminum plate - the recessed slots were cut on a Bridgeport mill with a rotating table:



Finally, the center hole was counterbored to provide clearance between the retaining bolt and the front cover, the degree marks were machined and the advance/retard marks stamped:



So it can fit like this and I can still use the sprocket covers:



The degree marks are every 2? on the cam sprocket face (4? on the crankshaft) for a total of 20? crankshaft change each side of straight up. My old eyes would not do well trying to read marks any closer - and it's easy to put the dot between the marks for 2? crankshaft resolution - close enough.

I could have cut more aluminum from the sprocket faces and bored holes to lighten them a little and maybe make them a little better looking, but they should work just fine.
