Well, though I've saved the pics onto my pc, can't seem to copy/paste them here. Here is a link to the Dyson Baidarka page, most of which seems to be under construction (else I would have emailed him).

Let me know if that works. It's basically a small, gear driven tubing bender. I can find larger models and smaller models, but nothing that will handle 1/2 and 3/4 inch tubing. I'm contemplating a conduit bender from a big box store (rhymes with Nome Keepo). Conduit is a bit softer than 6061 T6 though, so I don't know how much of a pain that would be.

Any input or ideas are welcome. Thank you.
