To do this properly, I would think you might build this up like a mast or a wooden column - in a multiple of pie shaped pieces(conceptually) with a hollow in the middle. This way the tube/cylinder can shrink or expand without cracking the entire cylinder. To keep the thing in round, it would be good to keep all the grain oriented the same way in each of the pie shaped pieces in relation to the outside of the cylinder(pain sawn or quatersawn for instance). Wood expands and shrinks differently in all 3 dimensiions so orientation of the grain would be important to keep the cyclinder as true as possible at high speed and at different atmospheric conditions over time.
This is one reason some furniture holds together with age and some self destructs(if you don't pay attention to grain).

hard put to find someone to run it after having dusted it off. I suspect that laminated stock would be a better choice than solid stock
for a turning blank. Solid stock can crack and is more prone to distortion. >>
I got into this late but Paul is correct. I laminate it out of 4 pieces of a
good hardwood such as maple and then have my local woodworking shop turn the
rollers. Not a hard job but it'll cost more than a 6 pack.
