5 minute epoxy
black epoxy resin
CNC Mill (I have a Sherline 5400 but you could build your own . see www.buildyourcnc.com)
1.35mm End Mills (www.store.yahoo.com/drillcity)
7/64" Drill bit
flat wood scrapper
EMC2 (download from www.LinxCNC.org)
LibreCad (Opensource version of QCAD)
Step 1: Design the board.
Step 2: Convert the CADfile to CNC
Step 3: Carve out the Lines
Note: During the Line carving phase I added to "Dots" one ay point (0,0) and the other at (9.1638,1.375). These will be used to line up the board during the drill phase
Step 4: Fill in the Lines
First step mix the epoxy with a "Little" bit of black resin.
Second, "frost" the face of the board with the epoxy.
Then scrap the excess off the board.
When the epoxy is dry, use a wood scrapper to finish it off.
Note: The photo shows 20 minute epoxy but it bleed into the wood. I found out that 5 minute epoxy worked better.
