Looks like I guessed wrong on that dimension for the wooden insert.
And now I see what it's saying. It's saying that the centerpoint for BOTH circle is 1/16" above the surface of the wood. That makes much more sense. I've attached an updated drawing.

I still don't get the interference fit between the wooden insert and the clamping plates. A 1.490" wide block isn't gonna fit into a 1.469" wide groove!

And again, I can save these in any format you need. Just let me know and shoot me your email address. I'll send them over.
