Hello All, This is an offshoot of the original Metallized Paper thread started by Darwin and is still ongoing. The material discussed and shown here concerns the uses of aluminum foil paper which I've developed from 100% cotton paper and common kitchen aluminum foil. Some results are shown first to generate interest. The photo below shows three hemispheres of various sizes (small is 12.7 mm, large is 18.0 mm wide) and a cyclinder with an oval top (8.7 mm wide). All were prepared from aluminum foil paper (home made), dapping block & punches and Aleene's Tacky glue. The reason for making The hemisperical shape was developed as part of the Wright Cyclone design which requires it as the forward part of the crankcase and to help suspend disbelief. Both the Wright Cyclone and the Pratt & Whitney R-2800 require a similar structure in the front. The cylnder was embossed, rolled and capped. Doesn't look like any engine part except a cut off bolt end...., or maybe a WWI rotary cylinder..., there's an amazing number of applications for this technique once mastered. The aluminum foil holds a very crisp embossing and forms without crinkling (paper does that somewhat on the inside but it doesn't show on the surface). And remember all the while, "Did I tell you it's made from paper"? Best regards, Gil P.S. There really is paper on the other side!!!
