I would like to create something in the rough shape shown below. My bike already has a pannier rack on it and I'd like to affix this structure to it, probably with plywood or similar forming a platform on the bottom, either side of the wheel. My question is what sort of steel tubing should I use (e.g. round vs square). The grey bars represent optional bracing which may or may not be necessary.
It would be great if I could do it this without special tools but there's an art facility in Edinburgh which I may be able to use if necessary. I have a small gas torch which I could use to braze joints to avoid welding. Could I braze square tubing to avoid having to try to bend it?
