re: Found picture of jig

Brian – The tube is held in the jig by two spring clamps . I then take a curved pattern and lay out two lines a 1/4 " apart. Then looking in from the open bottom I cut the piece out free hand . The jig makes sure the cut stays parallel as I move the whole thing on my scroll saw . The arm of the scroll saw goes inside the tube as I cut . The n I remove the piece from the jig and glue a precut pc of aged cedar in the slot and clamp it with three large hose clamps . Being as the cuts are at an angle you have to clamp the sides so it doesn’t slip upwards when tightening the clamps . Let dry over night . Had to do this 20 times .
