And it works! You can turn it in a complete circle over and over and . . .
Saw this on Steve Good's website and it grabbed me right away.
What should have been a one day project turned into 3 - Murphy's Law paid me a visit with the tension knob not tightening. It's doing its job now, but I need to order a new one. The underside where the tension rod is - well, the indentations that the tension rod sleeve catches on were just about worn smooth. I noticed if I apply downward pressure while applying tension, it will tighten up just fine. If I just move the tension knob horizontally, it doesn't take up the tension like it is supposed to. Anyway, I had a happy ending once I got that sorted out. Thinking of staining/painting the support and base a darker color and just doing a clear coat on the shells.
