"progress on the rotor is not spectacular..."

Perhaps not yet, but it will probably look spectacular when you're done.
Nice woodwork.  Because VAWT's haven't been perfected nor optimized, there's lots of room for artistry.

Am I correct in believing that the brake attachment will be replaced in the future with a generator attachment?  If so, then will you support the rotor with a large box attached to the aluminum cylinder, with the generator inside the box?

Hi s.w.

The next step (building the blades,see my response to v.m.)will be very spectacular.

The aluminium cilinder with the bearings will sit in a steeltube,that will be attached to the tower.The pronybrake will be sitting on the ground(need for continuous adjustment)The shaft going down must be stiff and light (again),to avoid extra bearings.I'm thinking of bambou again.
If you know a bambou 'forest',bambou sticks have an unbeatable stiffness/weight/price ratio.
I hope the pronybrake tests will allow the decision if it's worth building a alternator,kind of systematic aproach.

cheers,
Jaap
