Summer is fast approaching and I wanted to jump on the cornhole bandwagon this year. So I know I needed a drag knife to cut masking in order to paint instead of engraving the boards. After a few iterations, I finished my design and it works!
The body is made from the leftover parts when I replaced the z axis. The plates are made out of Corian which is nice and solid but super easy to mill. It attached directly to the spindle mounts m4 holes. I added a rubber band mounts so it has some spring in case the surface is not flat.
Very well, the blade from a Silhouette Cameo that I picked up at Michaels. I just did a .005 depth of cut on the line, no special software. Here is a closeup of some early tests
$25 for just the plates, if you replaced your z-axis you should only need a few screws and the cutter to get going. I am offering the complete kit for $60.
