How Do You Make A Self Healing Archery Target?
“Self-healing,” targets are a misnomer: Genuinely self-healing materials are very expensive polymers that return to their original state when heated, but none of these are used in the manufacture of archery targets. So-called “self-healing” targets are made of various closed-cell urethane foams, usually polyurethane. When an arrow is removed, the foam presses the hole closed so that it is virtually invisible. Eventually, the damage will be extensive enough to require replacement, which can cost $250 or more. Fortunately, the clever do-it-yourselfer can produce an inexpensive (less than $15 per target), portable and practical alternative made from materials found at the local home-improvement center. Cut the insulation into eight 24-inch squares. Plan on using two pieces for each target (producing a 4-inch thick panel), so one sheet of insulation provides enough material for four targets. Glue two insulation pieces together with spray adhesive. Spray both surfaces to ensure a firm bond.
