I located Amerimax in two spots here Ben, but it's all .010. The Home Depot in Grand Rapids has everything but .014. Even found copper flashing at one old Hardware store, but it was way too thin and $15.00 per pound. Think I'm going to order the 10"x 50'. If my calculations are close it would make close to 24,000 checks. That should be enough to warm up the barrel a time or two.
