Timber changes dimension with its moisture content.
Delrin changes more form temperature.
Metals does not change significantly at all.
So surely, grafting one material to another just creates different problems - stresses between the two materials. And the most likely manifestation of this is either a graft/lining/insert becomes loose, or the other material, be it timber or "greenline", splits or fractures.
What Chris reports seems to back this up.
Almost every new timber clarinet that comes my way here in Auckland, NZ (surrounded by sea, but with a mild climate) soon gets tight tenons (unless stabilised with metal). I deal with it, and because I never want to OVER-deal with it, producing wobbly joints, I often have to deal with it again later, and occasionally a third time. But eventually the joints are adjusted to the climate, with no further trouble. This applies to Selmer, Buffet and Yamaha.
I would far prefer this situation than to have them come from the factory with LOOSE joints.
BTW, Doesn't Greenline claim somewhere to be 5% carbon fibre? And if so, that would ideally be all for reinforcing at the tenons. Is that or is it not the case? If not, then Buffet being engineeringly silly re several other issues, I would hardly be surprised if that carbon fibre was in a form and location that had zero benefit to anything. Perhaps just for marketing?
