Notes: Kepro Circuit Systems, Inc. (800-325-3878) offers a cheap negative acting dry film photo resist copper clad. The development solution is a water based sodium carbonate (none of that nasty solvent stuff). I've had good luck with negative, 1:1, artwork on a laserprint transparency. One line between pin resolution. For great precision mechanical components of all types: Winfred M. Berg, Inc. (516-599-5010). They have this real neat 3-D (x-y-z) belt and sprocket product.
