Thanks guys. I was going to try one more practice piece before diving into that actual project I've been practicing for but I feel comfortable enough to go ahead with it.
JonB, technically, since it's squares cut from boards, it's alternating between side grain and end grain as it spins. In turning, you are certainly welcome to turn whichever grain you desire. One is more difficult than the other and the end results are completely different in appearance. See my first attempt:

I'm not looking for "easy", I'm trying to create evils in turning. I want to create something so hateful you want to just quit on it. I want something that catches and tosses itself out of chuck at 1500 rpm and I have to wait for it to stop traveling across the floor, yard, down the street, whatever. Just so I can retrieve it, chuck it back up and go again, just to see what I can make of it after the damage. This way, once you have accomplished something remotely decent after all that, the easier stuff is well.........easy. Challenge yourself!
I drill the inside of the forms initially with a long small drill bit then follow it with a forstner bit to the final desired depth.
I'm not a fan of cutting green for the reason of having to wait after the milling process to "see what happens". Bowls crack, hollow forms crack and/or move in mysterious ways and after waiting for it to dry, you have to come back and true everything back up to finish it. Green cuts easy, granted, but thus far my homemade hollowing tools have outperformed every hollowing tool I've purchased and they remove large amounts of wood very quickly and easily in dry wood.
Cut it, sand it, finish it, done. That's me.
