Now you are talking... Never measure when you can superimpose / trace...

Of course, the cam came with a nearly-free mostly-complete MKVII =) The guy I got it from actually had two

damagi - Can you also trace the outline of the cam profile and inside diameter with a sharp pencil and take a photo of just the tracing without the cam on the graph paper. A straight on view of the graph paper similar to your second shot would be great. That way, someone could transfer the shape based on the grid.
Sure is nice seeming one of these things in good shape. Seen a lot of melted ones.

Ya shoulda said PENCIL trace on graph paper!!!!:rolleyes: Dimensions of the cam surface thickness and the web thickness would be helpful as well as the hole location. Somethings are not 'imposable'.
FWIW, the profile should match the motion of the control sheave button when moved by the quadrant gear by a Mark 5/V.

You can purchase the speed control cam
I was given contact info for battles hardware in California. When I spoke with the gentleman. He said they can get the cam in metal for $97. Their number is 562-698-3714
QUOTE=gpartin]I am still interested, please let me know how it works out, I have my original Mark VII with the broken cam and recently purchased another headstock with the cam still intacted, was thinking of removing that one looking for a machinist as well........Thanks[/QUOTE]
