Seems like any WRT would do considering some of their tutorials. They can be made using barbecue grill if you need it cheap and can follow a fairly comprehensive guide. Not to mention that you can make this using a Pringles can. How to guide. EDIT: Oh, and a chemistry tip about removing rust from steel: just drop that shit inside a glassware that's big enough and fill with ~40% phosphoric acid. Works better on carbon-rich steel, but any type can be cleaned when soaked for long enough. EDIT2: I had to remove rust from one thing recently and made an experiment that's quite relevant. After applying heat to the object that had to be cleaned the rust almost slithered off of it in a way similar to cheap paint when treated with acetone. Phosphoric acid works, even without extra heat, but the result was significantly better and done much more quickly then without heating the object up.Antennas
