Nice job Tom. Experimentation is all worth it in the end. BTW, if you want a simialr product to Cold Weld, without the skunk smell, then try Milliput. It's a two part epoxy putty, which can be moulded, tapped, drilled, sanded, filed etc, and blends very smoothly. It's a British product (well, Welsh, to be exact!), and is available from some outlets in the 'States. I've used it for well over thirty years, and can't find a fault with it. When it sets, it's rock hard, and I once made a temporary filling for a tooth with it, which lasted about five years!!
