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

hi rodrigo, i have been meaning to write to you about this but terrible/spordaic internet connections have made this difficult.
personally i'd use angle section aluminium rather than flat, then it won't twist, and screw it the the back of the board rather than the sides.
you could also then use the angle section to mount the board to a stand or something. two or three lengths along the back of the board would do the trick i reckon.
i hope this helps!
very best
