Just working on repairing the seat back on the Pietenpol and thought I'd post a tip that has been mentioned before but it works so well it's worth repeating.
When cutting sponge foam such as is used for upholstery and cushions, use an electric knife. The one I use is one that came with a bread slicing setup, but most any electric knife will work. It cuts straight and clean through foams, unlike trying to use a knife or scissors. Mark your line on the foam with a Sharpie and just let the knife ease through. It'll cut as straight as you can mark a line with a ruler, or follow curves as needed. Be sure to rinse off the knife blades before you put the knife away, or your whole wheat bread will be "fortified" with foam dust next time you slice some ;o) Oscar Zuniga San Antonio, TX mailto: taildr...@hotmail.com website at http://www.flysquirrel.net
