Even if the bearings in the blade spindles
have went bad in the most common 2 blade type
it's usually the bottom ones that go bad first
and even tho' they're sealed the seals go bad
in time and all that dust,chaff, moisture in
the lower part of the deck...really plays heck
with that lower bearing ! ...in the meantime
the top one can be good as new....so if you get
a 2 bladed deck you can make one good spindle
out of 2...probably. The whole spindle can be used,
the blades of your genny can be mounted
with very little modificaation. Where the pulley
is/was can be used to put your plate for the
magnets...if a home brew alternator. Or the
pulley can be used as part of a flexible
coupling.
That spindle was probably designed for
handling some of the output of a 8 to 18 horse
engine at 2 to 4 thousand revs with the tips
traveling at near sonic speeds...so as part of
a HAWT it should be able to handle 5 or 800 revs.
....but if you run across an almost good
bearing ...in my experience, it's a waste of
time to try to salvage it, new bearings are
quiet because they are polished to a mirror
finish...once that surface has become damaged
by dirt or rust ...forget it ...unless you like
the neat sound of ( rrrrrr.rrrr) of a bad bearing
at 2 or 3 in the morning.
There is also the headset of a bicycle
especially for a VAWT
....coming soon in my diary...
should be entertaining and useful for some..
Thanks for bringing
it up tom...
any pics of your
current project or
did I miss it?
