Simple solution - make the fitting a little bit longer so there is room to
get the bolt in from the top.
In general, all of the fittings could stand to be a bit longer to allow easy
access for the hardware. Mike Cuy pointed this out on his video many years
ago.
This is a common design mistake. I remember many years ago when I was
working on my first job out of college. My job was to design a piece that
was to be removable from an airplane, attached by three bolts. I proudly
showed my drawings to the chief engineer who looked at it and said "The
mechanics are going to hate you. You left them enough room to get one click
of a ratchet on each throw. It'll take them 15 minutes of wiggling a
ratchet to get that pylon off. Go back and redesign it so they can get at
least a 90 degree throw on their wrench."
It is VERY important to make sure the bolts go in with head up or forward.
That way, if a cotter pin breaks (or is forgotten) and the nut vibrates
loose, the bolt will be held in place by gravity, hopefully long enough that
someone will notice it and fix it.

Subject: Pietenpol-List: Re: Lift struts
Dan;
I realize that your photos are from when you were in the fit-up stage, but
the lift strut 2 image illustrates a very good example of some of the places
where a built-to-plans Piet makes it difficult to install hardware the way
all of the "best practices" books (Bingelis included, Mikee!) say to do
it... bolt heads up or forward.
Where the lift strut lower fork attaches to that tab, if you use the proper
length AN bolt you can't get it into the fitting... the fuselage side fabric
is just too close and you have to install the bolt with the head down or
else try a shorter bolt with a shallow "shear nut" or castellated nut and
see if you get enough grip length. This is only one of several places where
the same condition can occur. There is also a place where the top end of
the strut X-brace cable requires a clevis pin to secure it to the fitting,
but the end of the strut is too close to the attach point for the cable
attach fitting and the pin has to go in with its head down.
On the first annual that my plane had (the A&P was not very familiar with
experimentals), he flagged those and a number of other spots where the "head
up or forward" rule was not followed. I wanted to have him demonstrate how
he would install that hardware, but refrained since he didn't ground the
airplane because of those.

I don't know how to take this out. There appears to be some sort of lock ring.

That was the 18th just south of Rantoul. Was a little alarming at first but you
could see directly down through it so I classified it as a thin broken layer
which is not a ceiling. From a low angle, just really cool looking.
Also, as it got more and more dense, you could see the edge where it just suddenly
went away. All told, wasn't more than seven or eight miles.
Just an isolated thin scattered to broken layer at three or four hundred feet.
Probably the remnants of some heavy ground fog from a little earlier in the morning.
We were there around nine thirty I imagine. Eas a brisk fifty degrees!
Rantoul was a nice overnight. Quick after hours service, hangar at thirty bucks
and a courtesy car. If it looked like it was gonna be bad, had just enough sunlight
to head on down to Frasca.
