Hey all,
Many different opinions here on humidity and such things...however think of this...when you're blowing air through the instrument, it's warm and very moist...so the bore of your instrument gets warm and moist. However, as Bucky Badger mentioned Grenadilla is very dense, and so the outside does not get this way. So you have a warmer, moist inside and a cold, dry outside. The moist inside is going to expand a lot compared to the outside which will shrink/contract, and that's when the wood just gets too stressed and cracks. I agree temperature has a lot to do with it, but I think that humidity does too. Keeping the inside and outside of the oboe at a relatively constant humidity makes a huge difference!
(Sorry if I'm coming off as a big know-it-all...I'm no big expert on this subject...)
