15. Tully likes to put screw recesses in the steering shaft to give the U-joints a secure mount. He mocked the shaft into place with the U-joint and marks the placement of the set screw. He then dimples the shaft with a transfer punch, followed by a center punch. Stainless is very hard, so starting with a ¼-inch bit Tully drills the hole, and then progresses to 5/16 with a drill press. He then installs the U-joint and tightens the set screw with a little blue Loctite.
