How To Use Rinehart's Brain Ridge®   Final Generation's patented Brain Ridge® has been especially designed to add ease and efficiency to your mounting. Just cut the antler base to fit over the Brain Ridge® and screw the antlers to the manikin. It's that easy to get anatomically accurate antlers. Step 1: Trim skull so that measurement A (antler base to back corner of eye) is the same as it is on your tanned deer cape. Step 2: Drill three holes (two in the front, one in the back) into the skull plate. Make sure holes are at least the diameter of your screws. Step 3: Apply adhesive (hot glue, epoxy, Bondo, etc.) to the underside of the skull plated and place antlers on the brain ridge. Step 4: Hold antlers in position until adhesive material is set. Make sure measurement A matches tanned hide measurement. Step 5: Drill screws into position so antlers are firmly attached. Caution: Skull plate will crack if screws are drilled too tightly. Step 6: In less than two minutes your antlers are Correctly aligned and ready for mounting. Rinehart's Brain Ridge® saves you time and makes you money!
