This is a cool technique you might be able to use someday then.
I make my living with inlay work and all my pieces are made with 8 to 500 parts that I mate using .003 offsets.
With the Micro fence I measure the bit, make the male part, then turn the dial according to the bit measurement from the dial caliper, add a .003 turn to that measurement, cut the female, fits every time like a glove. There is zero trial and error.
Or make a radius part using a circle jig, add or subtract .003 from the width of the part depending on which side you are mating. Swing another arc, the two parts fit every time.
I use .003, it works perfectly on the Micro fence and works perfectly in my CNC software. It fast and effective.
I made this particular inlay using the same technique, it's crazy colors, but that's up to the client. All the parts have .003 gaps of course when glued together that a perfect jointed part.

Everyone works different, if you are interested look over some of his videos, the one with the matched radii is nice, key really. Take it or leave it, but it works for me. My business is actually based off using the offset technique. Until I realized how simple it was to measure the bit and use an offset to make curved mated parts using this method I only made square and double square inlays. Now round inlays are actually faster and simpler for me to make.
This isn't the video where he actually demonstrates how to use the offset method, it's somewhere on his site. But for the other guys here is a quick view of how the mated parts look. Getting the curved parts to mate is really simple to do with the Micro Fence. It a similar doing the dados with their edge guide. The key is having knowing how far the a spin of the jig screw moves the bit in or out per revolution. So this technique could be used with any jig you know the screw information and a reliable way of counting or measuring the movement. We could make these if we wanted, but what a hassle. Believe me I made a similar jig on on my CNC it was not worth the trouble, I just buy them from Micro Fence. I did implant improvements on my jig though.
This video shows how to think in thousandths for wood working and why it isn't spinning your wheels.
