Ok, so the rosewood fretboard decided to start to warp, a couple of days after fret slotting and radiusing. 🙄 Over the whole length the difference between opposite corners is 1-1.5 mm right now. How much of a warp is acceptable? (To clarify: It is not glued on yet).
Edit: It is easy to clamp down, of course. But there will be some tension built in.
@swepri. I would think a warp in the fretboard would not matter at all. Once it is glued down to the neck it will stay as straight as the neck is. There is so little wood left in the fretboard that it will not pull the neck out. Just think of the fret board as only as thick as the wood left under the fret slot. That's pretty thin and why it will warp a little.
If you can press it down flat easily by hand, then it will be fine.
If not - might be a good idea to let it settle for a while - then level the gluing face.
Warping is usually caused by rapid changes in environment - maybe look into getting a dehumidifier?
Let us know how it goes - also some pics would help us help you - lay a straightedge on the fretboard to show us where it is not flat?

Measure twice, cut once...
Thank you! No need to panic then, since it is easy to press it flat.
We have experienced cold and dry weather in Sweden for a few weeks, but the temperature may have fluctuated a bit in the workshop. Indoor humidity is very low (I actually have a humidifier going where my other guitars live in order to prevent too much drying and fret ends to creep out during dry winters).
