I need to cut several small (font size 40) words into .016 copper sheet. Very thin. I tried repeatedly going over it with a razor but it is just not going to happen. I know there are such things as jewelrs saws that use a thin abrasive string but i dont know where to buy one and dont have the time to order one. I need this done by thursday. I have alot of chemicals (i used to be into chemistry) but i dont know what will readily eat up the copper and I dont have ferric chloride. Any ideas please!? its very important (a gift for a deceased loved one)
