*unless you include installation of a new boiler
I just had my boiler replaced with a fantastic new one. The first thing the plumber did was to put the old boiler outside our house on the curb. It was quickly taken by a scrap collector. This got me thinking about all the scrap copper pipe that was slowly filling up a bag in my kitchen. It's my copper, I should use the scrap!
I use copper for jewelry, printing, decoration, props, robots, and design projects. For some inspiration on what you can do with copper, just search for “steam punk” on this website! Sheet copper is relatively inexpensive, there are lots of suppliers on-line, but free copper sheet is... well... free! Also, if you only need small sheets (the 7/8inch pipe makes a sheet 2 ½ inches wide) why pay for the shipping? This project can be done in the time it takes a cup of tea (or coffee) to cool.
