    Default DragKnife

    I was doodling last night and drew up a drag knife
    DragKnif.JPG

    The blade is 0.5mm behind the center line , so it should turn the spindle axle when the machine go's around a corner
    it has 3 blade angle settings , 30deg , 45deg , 60deg with a 6.5mm diameter shaft and uses standard " utility knife " blades
    I HAVE NOT TESTED THIS

    I'm probably not looking at it properly, but the blade looks as if it is in the holder the wrong way round. IE. with the back of the blade facing the cutting direction.
