Platform CNC | Making a Drag Knife

I have always wanted to develop my own drag knife to cut cardboard, wood veneer, paper etc... In this video I 3D print and test a prototype and then mill the final working knife out of aluminum. --- I figured I had better add a mechanism for sending out the cadwork for the Drag Knife since there has been so many people asking for it. I though this might be an interesting approach! http://www.grunblau.com/DragKnife.html Please allow 24 hours for me to send you the files! The bearings you will need are 1/2" ID X 1.125" OD bearings found here... http://www.vxb.com/page/bearings/PROD/1-2inch/Kit7527
