Nothing too fancy, but a nice unique-looking piece. This was a scrap of 1" thick Red Oak left over from cutting an oval picture frame. Bowl is 11" long, 3.5" wide. The back surface is flat to sit against a back splash, back board on your dresser, etc. The front and sides are smooth curved.
The bowl was made by cutting the outer ring 1/4" thick with a 2 degree angle using a #5 blade. Use a 1/16" bit and drill vertically (not at the 2 deg angle) just inside of the cut line. The inner section could then drop down about 1/4" into the ring. The center was removed then resawn on a bandsaw to 1/2" thick, and the lower piece glued and forced back tight into the ring. The pilot hole winds up at the bottom edge of the ring, which is covered by the center, and in the top end of the center, which was cut off in the resaw, so no need to patch it. The center protrudes about 1/4" from the bottom of the outer ring. Round the sharp edges with a belt sander then finished with Howard's Feed-n-Wax.
This can be done with about any odd shaped piece of hardwood that you don't want to waste.
For the next one I may use a steeper angle - maybe 30 degrees - to make it easier to scoop change out, but that will need to be pilot-drilled at a little less than the cut angle so it is hidden. Then resaw the center to split off the bottom 1/4" (rather than 1/2" on this one) to glue back in.
