Offset / kerf when fitting one cut out into another

A kerf measurement tool may help:

You can find other tools using the same idea, but the general idea is to measure several cuts at once, then find the average to reduce the error.

You can apply the entire kerf width to one part or half to the part on each side of the cut. It’s easy to get the setting wrong, so practice on scrap before spinning up the irreplaceable veneers.
