I ran across a very interesting model shop on Etsy, NaturalBamboo (closed). Christopher has created a line of motorcycle and car sculptures incorporating various nuts and bolts. Each of his marvelous metal works is uniquely handcrafted, and I like his use of chain for some of the tires. He also makes novelty statuettes, including an impressive robot warrior, a ‘gone fishing’ pencil cup, and an out-of-the-ordinary cow coin bank.
Too many years ago I tried my hand at model making. It was a plastic model and took no imagination to put together. I had glue dripping everywhere, frustration took over, and I never finished.
Christopher builds his metal works in China, ships internationally, and can be found on Facebook (although I'm not sure how active he can be). Be sure to contact him through email firstname.lastname@example.org if you have a custom piece in mind. I wonder if he will ever make a dalek?
