Owl Circles Trivet/Coaster

Hardwood: 1/4" x 5" x 48" (Length is variable in 4.5-5.0" increments Backing material (optional)

1/4" End Mill (Stock Shaper Upcut Bit) 1/4" X 1/2" Steel Dowel Pins ([+0.001 diameter] 2 Minimum, 4 or more ideal)

1) Use a spoil board that you don't mind drilling through for the alignment pins. 2) Apply favorite method of double sided tape to spoil board and mount wood stock. 3) Add a grid of 1/8" spacing aligned to the straight edge of the workpiece and the left hand edge. 4) Import the Side 1 file and align to 2.5" X, 2.5" Y (assuming a 5" tall stock). 5) Cut the alignment pin holes first using "inside line", Helix, to a depth of 0.55". 6) Install dowel pins just in case double sided tape lets go. 7) Cut all lines "on the line" to 1/8" deep or half of stock thickness. 8) Recut each line in the opposite direction to clean up the rough edge. 9) Cut the circular profile "outside the line". 10) Remove wood, and tape. DS tape the other side. Flip wood vertically, reinstall on alignment pins. 11) Clear Side 1 SVG file and erase previous cut history. 12) Align Side 2 SVG file 13) Cut the new pattern to depth of 1/8" deep. 14) Assuming stock is slightly thicker than 0.250", progressively recut one of the lines at 0.005" deeper until the side 1 pattern shows through. My material choices ended up being 0.025-0.030" thicker. If you know this ahead of time you could split the difference on each side. 15) A backing material can be cut using just the outside profile cut. 16) I did mine with the stock shaper 1/4" bit and am only disgruntled with the amount of hairy shavings that were left over as the curves make sanding these more difficult. Might be worth going over the whole design with a downcut bit.
