I recall having done a calculation on the torsional strength of the C channel and comparing it to
a Shine bar, but danged if I can find that spreadsheet.  I think that what I chose was not too far
off, esp. considering available sizes.  Another thing I had considered was about what point a C
channel section twists - it's not on the member itself.  I forget that result too, and in the end
I think I just disregarded it.  The Cheapass Bar is just that - cheap.  It's easy too.  Cut,
drill, bolt, done.  It's better than nothing and far cheaper than a Shine bar.  Sorry, no
apologies for it!
