thank you thin shell. very interesting.
I see my case will need reinforcement patch of 1-2 beech veneer from the inside, sonor did it anyway by its own. Now I have 2 brave ideas:
1. Use something inflatable, like a gym ball, to slightly loose the crack area and place the walls exactly one against another. They are like saw there. And also precisely position the separated peace of wood. Looks very risky.
2. Make a reinforcement ring from 2 ply of beech and come 2" wide to reinforce entire perimeter of the shell. This will change its sound, but wil make it symmetricaly and better spread the load on the damaged area. Also risky.
As an alternative, to 1. is plase everything with razor, and to 2. use small ractangular 3ply patch to cover the place. What do you thank?
Btw, is it possible to rename this topic to "teardrop floortom repair", or smthg, as I am not blaming delivery, nor advocate local pickaup selling. I would never found anything valuable in my local area, so ebay and postal delivery is blessing, even if smthing like that happening.
