Hi Guys,
Today I've finally managed to complete my cardboard & styrofoam kammback and perform some tuft testing.
First tuft testing of my kammy - YouTube
Sorry for poor quality, but weather was getting bad and I was in a hurry to make any test. I had to use my old cell phone's camera because my webcam turned out to be a complete crap.
I need to improve my improvised tripod mounted to Berta and hopefully if weather will allow I'll try to roll another film from #2 tuft testing session tomorrow.
Hopefully you'll see that flow is attached to the kammback with slight turbulences on the edges, and big turbulence on the end because sides of the kammback are longer than the top (kardboard size was limited).
