My Latest creation, this one has been a long project in the making. All built from scratch. Lots of original ideas. Works remarkably well. Even the driver boards were designed with the help of my brother and I. This CNC mill was specifically made to cut balsa and foam. It's quite accurate, within .01" tolerance which is plenty for rc stuff. Now I can finally focus on some RC planes I've been wanting to build.

People would be very interested in a low cost, even DIY, CNC machine.
