I recently made a coat hanger from old skateboard truck bases. The original idea came from Steve Wolfe with Solid Foundation Skateboards. I saw the one he made for himself that he had nailed to his wall. I finally decided to make my own.
I used five Destructo truck bases on a 32 1/2 inch long piece of wood. I put about 4 1/2 inch space between the outer bases and 5 inch space between the inner bases.
