I've reached the point of installing the fan. Weighed, assembled, and on the spokes. Baker's book says to tighten the spoke nuts in sequence for even tension. I started with each nut flush with the spoke. After several passes I have everything seated against the shoulder of the spoke. Several nuts have no more travel. However, several could still go another couple of flats.
Do I leave as is with even tension or turn the last few nuts a few more flats? I have argued with myself but now through myself on the mercy of the court.

Stop arguing. If you argue with yourself, it's a lose-lose situation. Either install another another lock washer, or double-nut them. I don't remember ever running out of threads.

Re: Aermotor 702: how tight is enough?
I didn't mean to say that I had run out of threads. Some nuts are completely seated with the band tight against the shoulder on the spoke, i.e. its as tight as it can get. In some cases with the same number of turns, the nut could be brought down an additional flat or two. Again, the hoop is seated against the shoulder.
I believe this is because some spokes may have slight bend. My conclusion is that all of the nuts should be the same number of turns in order to keep the hoop as close to circular as practical. All are tight so this should work. After all, it's not a swiss watch.

Yes, and it's not the Mona Lisa. Snug them all down where they are all about the same tight, regardless of turns. Don't over tighten, it's just soft steel.

Yes it is indeed soft. Thanks for the experience. I appreciate it very much.

When you put a wheel on an Aermotor windmill. Tighten the nuts on the spokes that are attached to one end of the hub. Then tighten the nuts on the spokes on the other end of the hub. Tighten them, do not count revolutions. Seating the outer bands to the ends of the spokes is what will make the wheel as round as it is going to be. If you leave space between the outer band and the end of the spoke, when the wheel turns, this will allow movement. This movement will either wear on the outer band or the spoke or both. Once the nuts are tightened on the spokes (outer band), then tighten the nuts/bolts on the inner band. Note: install loosely the nuts/bolts in the inner band BEFORE tightening the nuts on the spokes/outer band. That is all.
