if i were you i would ask around for any oldtimers that have retired from the rewind shops in your area, or expanded
area.
often times these men could use the extra cash, and are looking for something to do anyway for various reasons.
coming up on winter months means they can't be dinking around the garden and will be stuck with the old lady
all day,,, perfect time for a project to get them out of "her" house anyway.
i am sure it is a time consuming process, but can't imagine it takeing 40 hrs to rewind, a good winder could sketch up the
type and number of windings, turn count etc surely in a half day and have time for tea and a nap or two.
then another half day to strip the field and armature, followed by cleaning up the cores.
so maybe he has to make up some wooden coil formers, bet he has done that so many times over the years he could do
it in his sleep anyway,, so give him a half day for that
outside maybe 3-4 days tops, and likely a bit better than than unless is wife has him doing honey do's along the way.
the thing is, there are other SOM around that will need rewind at some point, find the right retired guy and he has a ready made
part time deal where he can make some bucks and guys can get their generators rewound.
its a win/win situation.
ask around i bet you can find just the guy
the problem with shops these days is they have been busy so long during good times rewinding modern stuff, where they can
find all the documentation direct from the manufacture or even get the prewound coils from the oem
this speeds the process, all they have to do is burn out and strip the cores, clean/paint and reassemble the thing
i bet if they had all the spec's on your genhead they could probably rewind it in a couple days no problem.
even though it would be still expensive it would be about half the time of what it would be as a one off oddball
with no documentation that no one still living there even remotely remembers.
ask around, you might get lucky
