[chbot] Fw: Alluminium in small quantities etc for wheels

Sun Feb 15 23:55:41 GMT 2009

I have used a business here in chch called "the little metal(s) company". 
They sell all sorts of sizes and will cut to lengths less than a metre! I 
once bought 30mm of brass off them and they had no problem with that. They 
have alluminium, brass, copper etc in every shape and size imaginable and 
are very well priced. I was building a miniture steam engine to try out my 
new lathe and milling machine. I am also happy to machine small jobs for 
people if required. I love a challenge!
