I was rebuilding a transmission and had all the parts laid out on a table and my 2 1/2 yr old son asked me if I was building a robot. That night I woke up at 3:00 am and built the first one. Since then I've taken several requests and done art shows to sell these creations.
Most are made from auto parts and wrenches. They are stout, but are still just sculptures. They have fragile aspects. Great for garden or garage art. Or simply a gift for a gear head.
