These are plans for all kinds of interesting things you may or may not have ever thought about building. Many are scans from old books and magazines, now in the public domain. Others I have drawn and engineered myself, usually the ones I charge for. I'm a mechanical engineer with a long career of designing and building special machines and automated manufacturing equipment.
