Excellent results on my first test for CNC cut cross lap joint! Video below.
I’m using my LowRider v3 CNC to cut “test” spars and ribs for prep for the torsion box, my result was fantastic. The LR3 CNC is calibrated for dimensional accuracy. My test cut was based on the exact thickness of the plywood (as measured with calipers) as the width of the notch, and exactly half of the height that was to be cut as the depth of the notch. IMPORTANT: I did remember to enable the “Overcut” feature so the inside corners would not be a problem. By use of a hammer to drive the two resulting pieces together, this test was a huge success with a perfect result! Amazing friction lock on the two pieces.
