David Kirk Posted October 25, 2004 Share Posted October 25, 2004 I've been wondering if you could use some ordinary good quality art cardboard, soak it in varnish or resin of some type and then dry it out for use as a battery box material. The old stuff seems a lot like treated paper. Link to comment Share on other sites More sharing options...

H.I. Gosses Posted October 26, 2004 Share Posted October 26, 2004 If I am not mistaken the thick cardboard started life as gasket material. ( You know, between the valve cover and the mainblock etc.) I have reams of it in all sort of colours and thicknesses from a defunct engine-repairer. The "copper" contacts, are usually Phosphor-bronze. This is "springy". Ordinary brass is plastic (i.e. it takes a shape), to maintain good contact the strips should be elastic. Does anybody have, or know a source of, 2 D-cell metal, round, flashlights? For a small series of DIY-robots, I would like to use them asremote's Link to comment Share on other sites More sharing options...

Robotnut Posted October 26, 2004 Share Posted October 26, 2004 If you would have ask me a month ago you could havehad a dozen of these. I picked up a box of these oldstock lights from a guy who used to own a hardwarestore. They were from the late 60's , early 70's anddidn't sell due to the funky colors. I sold a few and gavethe rest away. This last one will be appropriate for thekids to use on Halloween. You're welcome to it afterthat... :P Link to comment Share on other sites More sharing options...

The old stuff seems a lot like treated paper.What you are looking for is called "phenolic". From the San Diego Plastics site: Phenolic sheet is a hard, dense material made by applying heat and pressure to layers of paper or glass cloth impregnated with synthetic resin. These layers of laminations are usually of cellulose paper, cotton fabrics, synthetic yarn fabrics, glass fabrics or unwoven fabrics. When heat and pressure are applied to the layers, a chemical reaction (polymerization) transforms the layers into a high-pressure thermosetting industrial laminated plastic.
