I am not responsible for the foil once you start handling it. The smallest burst of air can flip the foil over, bend it, or tear it. If you fold the material on accident you can smooth it out easily by putting it back in the tracing paper and running your fingers over the tracing paper until it is flat again Kit Contents Lundahl LL2912. 1 Tube-Wringer Model 401. 6" of white Evidence Audio The Lyric HG™ hookup wire. 6" of black Evidence Audio The Lyric HG™ hookup wire. 2 feet of WBT 840 Lead content silver solder. 1 sheet of either 1.8µ or 2.5µ aluminum foil. 2 micro plastic clothespins to use, if you wish, to tension your ribbon. Tips For Cutting Foil UPDATE! I have a video that shows an alternate method to what is described below. I will email you the link once you make a purchase. Past purchases are welcome to the video. Send me an email from your registered paypal email address. Use a cutting mat not a cutting board. You can find on amazon or a local hobby store. Make sure to clean the mat of debris to keep your cut nice and straight. Use a very sharp cutting tool (exacto). Cut slow and steady. Avoid starting and stopping. I like to keep the foil between the two sheets of tracing paper when cutting it to the desired width. This will help to avoid tear out on the edges. Buy some extra tracing paper to store the foil because every time you make a cut you will also cut the tracing paper and eventually run out of the supplied tracing paper. Use a flat ruler as a guide and apply enough pressure so the material doesn't move on you. Cut the ribbon to an oversized length. I like to cut a piece the entire length (longest dimension) of the raw material to make sure I can handle and install the ribbon properly. Have patience. It takes some practice. Try practicing on regular foil first to see how the material responds to cutting. You can also buy some 0.3µ-0.6µ imitation silver leaf to practice on. If you can cut this you will have NO PROBLEM cutting a thicker foil. Tips for Corrugating Ribbons of 1.8um to 2.5um. Buy some tracing paper. Tracing paper is great because you can see the ribbon through the paper. You might need to double up the tracing paper. Also, tracing paper has low friction so be careful when moving it around. The ribbon can slide out. Cut small strips of the tracing paper and fold it in half. Unfold the paper and place the ribbon inside the paper at the fold and make sure it is laying straight. Fold the paper again so the paper is on both sides of the ribbon. One edge (length not width) of the Ribbon should be at the fold. Place one end of the paper into the tube wringer. Try to make sure that the fold in the paper is perpendicular to the gears. You want the ribbon to be as symmetrical as possible. If the ribbon is at an angle when you place it in the tube wringer you will get corrugations that are at an angle. Turn the handle. Done! Packaging Of Foil I package the material between two pieces of acid free tracing paper. The material and tracing paper is then sandwiched between two pieces of thick poster board. Domestic Shipping The kit will ship USPS priority mail. International Shipping The kit will ship USPS priority international mail. Returns Returns are NOT accepted, but I will replace the material if it is damaged in transit. A few nicks in the material edges will not be considered damaged. This is normal for this thin of a material. International Buyers – Please Note: Import duties, taxes, and charges are not included in the item price or shipping cost.
