Oh my gosh! I never thought of that, and I actually have rivets. The flashing idea with rivets just made thoughts of the next processing day way better. Glad I popped in to read this morningRod, I made my cones out of a heavier aluminum and riveted the seam. If the duct tape fails, you might could try a quality pop rivet. Aluminum rivets should hold and are easier to pop by hand if you don't have access to a pneumatic gun. Mine I know will last my lifetime. I made three different sizes.
