Hello, going to try my hand at inlay done on my cheap china mill. first, just doing a 1" circle, make a pocket, simple enough, then a profile to fit into the pocket, here's where it all goes wrong, it's either to big or to small to fit. now I can change the size of the circle, I'm sure, but that wont work on an imported design, which is where I'm heading. need to make one fit in the other with a perfect fit. I have been able to get it so both are exactly the same size, but they wont fit together without some clearance, just don't know how to get the clearance!

Thanks for any help
