I found this and thought that it might be useful for anyone wanting to make their own wire frames or anything else involving steel. http://www.paramountbrowns.com.au/hardware-machinery/products/machinery/metal-working/rolling-forming/hand-ring-roller/ It's a hand ring roller. For all those people in SA it's from Paramount Browns, I am sure everyone in SA knows the place, and it's a fairly reasonable price too $141.55 online or $149 instore. Personally I would drive there to get it as postage to Munno Para is $10.95, which makes it more expensive than the in store price and I drive past it every day. I am sure for people in other states you would be able to find a similar product for the same price however just as an example the shipping estimate to Sydney postcode 2000 is only $19.95 so could be ok. It says that it will do 6mm round and 25mm x 4mm flat bar, however you may be able to modify it to do slightly wider bar won't know till I get one.
