Seasonal setup and trem claw tightening

Hello,
I noticed that now that summer came, I needed to slightly screw the screws of the trem claw, in order to achieve the same parallel position of the trem plate as before.
I had many incidents like this, back from Oct->Dec when I finally stabilized the guitar. I hadn't touched any tool since then, neither did I change strings. However lately I noticed several open notes going flat according to the digital tuner, so i re-tuned the guitar only to find out that the trem plate angle was not how it used to be and is supposed to be, but had an angle towards to the bridge. So slightly I tightened the two claw screws. Now all readings, measurements are like before.
My question is : is possible that weather affects the springs/claw/screws ?

Are you sure that the problem wasn't more with the neck bow changing due to the weather? First thing I'd check is the relief, then return and see where your trem is.

Definitely, I measured the relief first, no change at all. This neck with the KTS titanium rods is a beast. As a matter of fact I had been doing various measurements on the guitar since December, and I always found the values to be constant. Lately I felt that it needed a slight tuning, as some strings were slightly flat, but this caused a rather noticeable lift in the trem plate angle. Therefore I had to slightly screw the claw in clockwise about 1/16 of a turn.
I must note here that I have the 3-springs in parallel configuration on the uv70p, and I found out that the 7-string with 9s is substantially more sensitive than the 6-string with 10s. The slightest change in tension is reflected back in the system. I had this in the beginning as well and kept blaming the instrument for what maybe is inherent to 7-strings. I thought I knew all about floyds, but the uv70p sent me back to school.

Where did you keep your guitar? Just wondering if we just leave it inside the case, does it altering your neck setup.

If all else is ruled out, it's your strings. Having not changed them in 6 months, that makes sense. When you put a new set on- you'll see you have to adjust the claw again.

In its case, but the sun is hitting right on it in the afternoons->evenings. I guess this has an effect.

It could be the strings. But Jesse was right, I was very hasty to rule out the added relief due to the temp increase. In the last months I used to measure relief by eye, lately I was amazed I didn;t get no buzz at all in 1st string, 1st fret. Well, I had to take a little relief to make the numbers as they were. Relief was definitely a factor.
I apologize for the false impression. Sorry Jesse!
So moral of the story : even beastie necks do need adjustment at least twice a year!
Now if Ryc's theory is true, I'll have to redo the setup after I change the strings. But I guess its an easy job to do after all the "training" I got!

Unless they're stored in some hermetically sealed room at very cold temperatures with no tension on them, any strings will degrade over time. strings that are under tension for 6 months have degraded- in or out of the case. They may still be completely playable, but they're not going to be as "solid" as new strings. They'll go out of tune faster and usually need more tension to balance the springs. I don't know the metallurgy of it, but this is pretty much true of any strings.

Glad you got it figured out.......Jesse is a pretty smart guy. If he's offering help- He's probably pretty damn close to nailing down the problem.

Re: Seasonal setup and trem claw tightening

LOL thanks guys.

I'm way too nerdy to measure relief by eye. I put a capo at the first fret, do the last fret with one and and then use feeler gauges to check the relief.

The only things I trust checking by eye are major issues like humps in the fretboard, high frets, back bow and overall profile (like where generally the relief is).

Hey now, there's nothing wrong with measuring by eye.....
