Tom,

I'm sorry you got a bad impression of John Wright, Sr.  One thing I ask on
our forum is that no one describe anyone else in a disparaging manner.  We
insist on maintaining a civil tone.

In this case, John is someone whom I respect very highly and he has been
helping people on a purely voluntary basis for thirty years, that I know of.
Not to mention, his shop rates are way lower than the going rates in many
(?most?) shops.

My observation is that John's knowledge of Coupe mechanics is in the top
three in the nation.

After I moved from Iowa to Illinois I was only 70 miles from Springfield
where John lives.  I had him do extensive work on my Coupe to bring it back
to full safety and we discussed each issue and cost, often in person, and my
conclusion was that he treated me more than fairly and did not charge me for
many of the hours he spent and I was, indeed, topped out on what I could
afford.  (I've heard other A&P / AI mechanics say they don't want to work on
our planes because we, as owners, are unwilling or unable to pay what the
work is truly worth.)

After his retirement from being a civilian mechanic for the Air Guard, John
spent full time working on planes, probably about two thirds of them Coupes.
(Local friends prevailed on him to do their planes and club planes which
accounts for the rest.)

Requests for John to work on Coupes (and other planes) are probably double
to several times more than he can accomplish and he is (and needs to be)
very choosy about which jobs he does.  He has slowed down a lot due to age
and even more after medical problems a few years ago.  He has to be choosy
about what jobs he accepts and friends and long time EOC members get some
priority.  Then there are those who ask him to do pre-purchase inspections
and other work.

John's work capacity is limited and I doubt that he needs the money.  He
does this as a hobby and a favor to those who need it – up to the capacity
he can manage.  He has no employees and it can hardly be called a business.
He can't be pushed into doing work and being pushy with him would likely
produce negative results.

I think I've heard of John replacing center section spar assemblies.  I
don't know any of the mechanics of doing this (I am not a mechanic and I'd
sure better not play one on the Internet).  If John says it takes a jig,
there may be a lot of truth to that.

To replace a center section spar probably requires great care for alignment.
I don't know how tight those alignment requirements are.  Perhaps, if you
measured alignment on a couple or three good-condition-Coupes with a Smart
Level (electronic level, accurate to 1/10°) and aligned your assembly to
match the other, you'd be good enough.  I don't know.

It's true that most aircraft construction is hand work.  However, ERCO was a
leader in automated aircraft manufacturing equipment and, perhaps, they had
some means of drilling those spar holes that would make alignment easier if
you had a used spar. I don't know.

I have heard of other spar replacements being done around the country.  I
don't know how well.  Remember the case in Alaska cited by Paul Anton a few
messages back.

Wish I could give you a more definitive answer on whether it really takes a
jig or whether it's really better to use a used spar with existing holds.
On those issues I can't help.

On dealing with John, I'd advise that he is worth knowing and trusting.
