Finally got around to trying my first inlay with this machine. Tried to challenge it by using a series of line widths, 0.5mm up to 3mm. Classic walnut and maple. 70x70mm square.

Used a 30 degree V bit, 2mm inlay depth, 1mm glue void depth, 1mm air gap above.

Plug and base (are there real names for these?) - Ran the cut twice on each to clear up some fuzzy bits - suspect my feeds and speeds arn't quite right, but I was being conservative.

Glue time.... used some pretty standard PVA, that might come back to bite me but seems to be working.

Trimmed the excess slowly and gently... reveal time!

Some sanding through the grits, add oil... et voilà.

Not perfect; looks like theres some reaction going on at the interface between the two woods, and I think there was an imperfection in the maple or the plug cutting that caused that slight discontinuity, but overall quite pleased for a first attempt.
