I was hoping for some advice… I started turning this 5-1/2” piece which has some rough bark on one side (which I think is kind of cool). If I continue widening the inside, it seams like the wall will lose integrity on that side. But the walls seem way to thick to leave it as it is. Should I keep going and turn the walls thin?
Also, does anybody recognize what kind of wood this is?
