Too thin spruce top?

[Henning]

Hello, I was given a small acoustic guitar that somebody, most likely have out of mistake, sat on. I took it apart, repaired the cracks, thinned the top, changed the bracing (converting it to X), reset the neck and put it together. I start to worry that I've thinned the top too much. Maybe I have, maybe I havn't. Now if the top has been thinned too much, can that be remedied, please?
Perhaps, adding a brace of spruce or perhaps even carbon fiber under the top in the right place, without killing the tone too much.
If I press on the top, beneath the bridge towards the end block, I can make it flex noticeable. No other guitar that I've tried that on behaves like that. It's a smaller guitar 580 mm scale length, about 3/4 of full size. Can I try this in any other way then setting the strings on the guitar and try tuning it, please?

Best regards

String it up. You have nothing to lose. Maybe use an extra light set of strings first. Silk-n-steel maybe.

Most factory made guitars are over-braced and tops thicker than they need to be.  You might have improved this one.  Only time will tell.  I would string it with something light-ish, and keep a close eye on how it goes.

That was my intention, to improve it. As it is said the top of these guitars are generally too thick. Asking myself, should I try .010 or silk'n steel strings?

I've bought a set of D'Addario EXL120 Nickel Wound Super Light 9-42 Electric Guitar Strings 9/42,. It was recommended by the music store. He said it would produce a warmer tone too. By calculating with chatgpt for a shorter scale length guitar (580 mm) , it would cause a tension on the top of about 300 N (pull force). Regards
