1/2 " 2 1/2 " r^-> 1 1/4" Slowly feed the jig and the stock past the blade, keeping the back of the jig firmly against the band saw's fence. Cut tapers in the faces of the stock, turning the stock 90° between each cut. The blade should exit the stock at the middle holder, 30" from the bottom end of the stock. When you've finished this step, you should have a four-sided taper. If you were to continue cutting the corner tapers in this manner, they would exit near the bottom of the post. This is because the post is wider when measured diagonally than it is when measured across the face. To stop the corner tapers at the same point as the face tapers, you will need to cut transition curves in the corners. To figure the radius of these curves (R), subtract the width of the stock (W) from the diagonal measurement (D). Then subtract After cutting the face tapers, mark the transition curves on the corners of the post. I made a simple marking jig to do this quickly and accurately. Cut the transition curves with a coping saw. Take it slow and monitor the lines on both sides of the cut. Cut on the "waste" side of the line. Later, you can sand or file the curves to the line to shape them precisely. |
