Cut the head off a 3⁄8-inch threaded bolt, leaving about a 6-inch shaft. Drill a hole in the base of the antler to accept the shaft; move the bit back and forth to widen the hole. Set the shaft in the hole with two-part epoxy, making sure that approximately 4 inches extends beyond the antler base.
Thread two 3⁄8 x 11⁄4-inch rubber washers and one 3⁄8 x 11⁄2-inch fender washer on the shaft; follow with another fender washer and two rubber washers. Attach the wing nut.
Drill a 3⁄16-inch hole horizontally through the bottom of the other antler base. Tie off 3 feet of black bungee cord.
- Mount the antler so that the two fender washers are against the top and bottom of the treestand floor. Tighten the wing nut.
- Tie off the bungee-equipped antler to a shooting rail or nearby tree limb directly above the mounted antler.
- To rattle, grasp the top antler and tickle the rack below.
