Re: [oddmusic] DIY truss/bracing solutions? (for very low tension)

Man, O Man!!

I love your set up!! Now *this* is an inspiration!

Have you considered gluing or screwing square aluminum channel stock to the
backs?

Something like this works mainly because of the shape which resists
bending. Steel would be even more resistant but much heavier and probably
overkill.

Or.. if you can release the tension and drill a hole and then fill the hole
with aluminum or steel bar.
