Only thing with apple, and all fruit bearing trees, is that the wood
cracks rapidly; like while you're turning it. I've had some that was
plain, like Harry said, but I've also had some with great grain. I'd
suggest turning it right down to finish thickness, if you hear it snap
(crack), keep soaking the inside with oil (Danish, mineral, tung, ?)
and let the oil replace the juice flying out as your turning.

It's a fun wood to turn.
