Wow making progress I’d love to see this to a finished file I just don’t have the knowledge or experience to get it there…Thanks for working in it
Almost there:

Unfortunately, failed to:
- add additional geometry for the outer profile to allow V-carving the perimeter
- remove the grey highlights from the white area of the bird
- properly separate the white areas of the runway
Anyway, the basic principle is to:
- calculate how wide an area one needs for V-carving to the desired depth
- add an inset along that centerline
- adjust both paths so that things are rounded off so as to eliminate peaks
Would it be possible/ easier to cut the interior around the eagle and runways out completely with a straight bit?
It would depend on the scale and size of the bit relative to the piece. Basically inlay options go this way:
- straight bit, inlay with vertical sides
- smallest detail limited by endmill diameter
- any narrow feature must be at least endmill diameter+10%
- V-carve with angled sides — through cut
- all inlay pieces must be same thickness
- detail limited to one’s workholding ability / options / patience
- V-carve inlay with pockets
- requires specialized software or careful toolpath planning

Is there a way to stop it from cutting all the way through?
Further adjust the paths, or use a tool which limits depths, or use a shallower angle tool, or a thicker material.
I figure I’ll just fill w/ powdered enamel and epoxy.
Anyway, finally found time to cut this w/ the right endmills:
Need to get a loupe from work and deburr the edges and then work out some way to infill the colours.
