Thanks, Lee
One thing I have yet to do, and that I've done on the other baffles, is to pin the baffle material to the frame. I drill small holes around the compass points, and use long ball head sewing pins that I bag from Sarges kit; all black pins except for one red one facing forward. It helps a lot in keeping the material centered.
But, like I said,.. and this is silly since its a day old,.. I'd suggest the plastic frames as opposed to this bamboo, as the plastic has a beefier arrangement to close the loop. I saw metal closures with the bamboo frame, and, figured that was better. But compared to the plastic frame of my battle hardened 8" baffle, I'm guessing that the bamboo one will need to be replaced. c'est la vie.
