I would assume I got the thin-wall kind. I mean it looks pretty thin, but its very strong. I got it at Home Depot. It's the only metal conduit they had; sold in 10 ft. lengths. 3/4" inch.
I tried heating it up with a small blowtorch, and heated it for a good while, but it still wouldnt flex. I'm just plain stuck! If I cant bend them somehow, that $70 bucks for the already made braces is going to look easier and easier. I hate to spend that kinda money on something so simple though.
