Well, this was a first for me. Inlay. First lesson learned from this was to select thinner wood....both pieces were 1" thick (or less....grand total was about 1 3/4" thick when stacked). Thicker wood probably needed a steeper angle, I did this at 2 degrees (more or less), following a nifty video I found on Youtube (looked suspiciously like Dave...). I had to hammer the two together. Also, most of my scraps are all the same color/flavor of wood (outer ring/wolf are red oak, I splurged and bought a board), so after rigorous sanding/filing didn't loosen the fit any, I didn't bother to go to the next step and sand them flat while joined. Just stained and pounded together.
This'll definitely go on my "look where I started, and how far I've come" pile.
Pattern was a pic I found on Google, its a design for guitar string pegs/tightener/doohickeys. Enlarged it, threw it in Inkscape to TraceBitmap and remove the jaggy edges, added the circle, and cut. Easy enough to cut.
