I've written a series of three articles for a well-known kinetic art organization in the UK called Cabaret Mechanical Theatre. The first article in the series showed how to cut brass tubing, rod, bar, and sheet. The second article showed some tools and methods to bend brass. My most recent article describes how to solder brass parts together.
The techniques shown in the articles are commonly employed in my workshop. I hope you enjoy the articles and perhaps find them useful.
