Not a good thing.
My solution was to make a tightening tool.
As the picture shows a tightening tool may not be the best solution. I made junk out of the upper blade holder.
PS It cooled off a little bit today the temperature only reached 69.1 deg.
I create problem solving challenges and opportunities for design modification, not mistakes.
