Bolt it all roughly into position so it can be lifted. Then once it is
vertical just loosen the bolts a bit, line it up, and test, then tighten it
all back down.

Subject: [TowerTalk] Aligning rotor, mast and thrust bearing
My new tower project is moving ahead nicely. All major parts have arrived,
including the tower itself (a custom 8.5m x 0.2m diam galvanized pole). Now
it's just a matter of finishing the construction and installation.
I've been working on aligning the rotor (PST61), mast and thrust bearing
(TB3). I was thinking about bolting everything to the tower before they
crane it into place (suggested by the installer). However, I'm finding it to
be a challenge to align things correctly, particularly with the tower laying
down at an angle - too many degrees of freedom.
I suppose I could just wait until the tower is vertical, but even then it
seems like it won't be easy (since it was a custom build, I would also like
to confirm that the bolt holes for the rotor plate and the thrust bearing
line up correctly). If anyone has any suggestions / tips along these lines,
I would love to hear them.
