While we're on the subject of flexible wire.. I'm looking for a source of small diameter wire rope or cord, maybe about 1/16 diameter, able to go round a pulley about 1" diameter. I can find lots of aircraft control cable, but it al seems to be too thick for my needs. It doesn't have to be wire.. some kind of very strong cord would be OK as long as it didn't stretch much. Something like dial cord, but thicker and stronger. This is for a machine with parts that will be moved by pulling on wires. Hope this doesn't count as threadjacking ;) Neil -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
