Check out the “Let it Snow” Xmas 2020 Group youtube project!”
I related in another post that my best option for getting in some practice time is to practice at work, and that I practice outside since my violin with mutes is too loud for an office environment.
Plus I'm not ready to debut Damon's 5th Scheechophany in D.
Today I noticed that while I was playing my bow hair was right up against the bow while I was bowing. I thought maybe I didn't tighten it quite enough and re-tightened it. After the re-tighten I was playing better for a bit, then noticed after another 5 minutes or so that the hair was back against the bow.
After a web search I see that rapid temperature changes might cause this, and could also damage the bow. My question to the group is does anyone have first hand experience with damage caused by this sort of thing? Also, if I want to play outside should I leave my violin in the car so it gets acclimated, or would that be more harmful?
I haven't actually experienced this, so I'm just making a wild guess.
Is the screw you turn to tighten the hair loose?
Maybe it's somehow turning back on it's own from the tension.
My other thought, which I have had happen, is the wood wedge piece that holds the hair at the frog end has slipped out of it's slot a little bit.
Meanwhile, I'm sure someone with better knowledge will come along to offer some guidance.

I had a bow rehaired by a luthier a couple years ago. The next day I noticed the hair was really taunt, I didn't even have to tighten it to play. I unscrewed the frog and it was still tight so I drove back to the luthier, walked in and showed him what the problem was. He asked what the humidity was in my home, I told him what I thought it was, but within 5 minute's the hair was completely relaxed again.
Like Pierre / Fiddlerman, humidity definately plays he~~ on the bow.
