Fuel Tanks and Stringers

June found John working steadily every day as he installed the forward fuel tank and oil tank in the motor mount on the JNE Spirit of St. Louis.

.

Once the tanks were in place, John was able to begin the process of running the fuel lines, the tachometer cable, the throttle line, and more ~ from the cockpit forward to the front of the aircraft where they will eventually hook up with the engine when it is installed.

.

When we returned from our visit with the original Spirit of St. Louis in Washington, DC, John discovered the stringers he had were not long enough.   :-(

John tried to find a 20′ long Spruce board to cut new stringers out of … but ended up having to purchase a board that was 26′ long in order to get the straight, clear, knot-free wood he needed for the 1/4″ thick stringers that form the shape of the aircraft.

.

Once he got all the stringers cut and formed, he secured them in place by wrapping them with cord just as the original had been done.

.

Then he moved on to “framing” the door with wood and making the window frames.

To “Patch”, or Not to “Patch” …

Charles Lindbergh wrote of an incident in his book, about when they were checking the

fuel level of the original Spirit of St. Louis with a length of rubber hose.

The story was that the rubber hose slipped into the main fuel tank.

They had some discussion as to whether they should just go ahead and leave the hose in

there … or if they should try to find a way to get it out.

Due to the possibility of the hose deteriorating in the fuel, and possibly coming apart and blocking one of the fuel lines, the decision was made to remove the hose.

.

There is no discussion to be found to tell us HOW they removed that length of rubber hose, leading one to wonder, “… did a rubber hose REALLY fall into the tank?”

.

John questioned that himself because there is a 90 degree angle in the fuel filler neck, making it difficult to insert a piece of hose into the tank …  much less for it to get dropped inside!

.

That question was one John wanted to answer for himself while we were in

Washington, DC with the original Spirit of St. Louis.

.

Once again the portable VJ-Advance video borescope camera from RF System Labs

in Traverse City, Michigan came to the rescue.  :-)

.

John ran the borescope camera around the main fuel tank to see what the sides of the tank looked like.

.

Suddenly, right there between the forward tank skin and the first vertical baffle aft; and

between the top & second horizontal baffles down; John found a “PATCH” in the side of

the tank!

.

They had apparently cut a hole in that location in the side of the fuel tank to retrieve the rubber hose.

To repair the hole, they riveted a piece of plate over the hole and soldered around it to make

it leak-proof.

.

What did that mean for the JNE Spirit of St. Louis?

.

Well, to be an EXACT replica aircraft, John was going to have to put a patch in the side of HIS tank as well.

As much as I pleaded with John NOT to put a patch in HIS main fuel tank; John said, “The

original has one, so mine needs one too.”

I argued that he could simply TELL people that there is SUPPOSED to be a patch there, but he didn’t need to put one in because nobody would ever even SEE that patch since that section of the aircraft is covered with fabric!

John replied, “If I’m building an EXACT replica, it needs to be to be there!”

.

So, John took the time to “patch” his main fuel tank, even though there was no rubber hose for him to remove from HIS tank.  ;-)

Fuel Tank Patch

Once John completed the “patch” (seen at the bottom of the fuel tank in the photograph above)  he painted the tank to get it ready to put into the fuselage as he continues working on the Final Assembly of his Definitive Reproduction Spirit of St. Louis!

Beginning the Final Assembly …

Our visit to the original Spirit of St. Louis at the National Air and Space Museum in Washington, DC in March proved to be highly beneficial.

John learned that the fuselage he had built was nearly identical to the original.

The month of April found John making a few minor changes to the fuselage structure (such as lowering the instrument panel brackets just a bit) based on the information he learned off the original, and then he began the final welding.

74-hours later … he had completed all the welds that he had previously only ‘tack’ welded together.

From there, he sent the fuselage and tail-feathers off to be sandblasted.

At the time, they told John they would be finished in just three days …

A week and a half later … John was able to bring the fuselage and tail-feathers home again.  Lucky for him, we were having a wonderful, warm, sunny day here in the Pacific Northwest, and he was able to get all the parts painted right away :-)

He then installed the Trim Control Quadrant, the Throttle and Spark Levers, and the Seat.

With that, he has begun the FINAL ASSEMBLY of his Definitive Reproduction Spirit of St. Louis.

Spirit Visit

John and I have just returned from a visit to Washington DC, and the National Air and Space Museum where we had the rare opportunity to get “up close and personal” with the original Spirit of St. Louis :-)

We had the privilege of not only taking copious photographs, but also detailed measurements of many parts of the aircraft.  These details will help John be able to complete his definitive reproduction Spirit of St. Louis in the most authentically accurate way possible.

We were given the opportunity to inspect the Spirit of St. Louis with a portable VJ-Advance video borescope camera from RF System Lab of Traverse City, Michigan.

Here John is inspecting the area forward of the periscope on the port side of the Spirit of St. Louis.

The great excitement of the day came when John was using the VJ-Advance video borescope camera to inspect the area under the main fuel tank, and made an interesting discovery!

There, lying on the belly fabric, beneath the fuel tank, amongst the ‘dust bunnies’, a pair of pliers that had been in the Spirit of St. Louis from 1928 or earlier!

Bit by Bit …

Bit by bit, piece by piece, John is making progress on the JNE Spirit of St. Louis.

 

.

Despite being laid up for nearly three weeks from late January through the first week of February with a mean flu bug …  John was STILL able to get all the parts for the forward fuel tank and the oil tank ~ fabricated and put together before the end of February.

.

Once completed, they both slipped right into place :-)

.

John was also able to complete the re-work he needed to do on the cylinders for the Wright J-5 Whirlwind engine so we can now send them out to be chromed.

.

Once the cylinders come back, John will be able to finish assembling the engine.

THAT will be a grand day :-)

Moving Forward …

We finally made it through the first month of 2015.

It’s difficult to see very much progress, but we really HAVE been moving forward.

.

In between waiting for various parts to arrive so that John can keep moving ahead on the Wright J-5 Whirlwind engine re-build … he has been working on the second fuselage fuel tank and the oil tank.  Both of these tanks fit between the main fuel tank (that he completed last summer) and the engine.

.

All of the pieces for the fuel tank have been cut out, the baffle holes have been cut & rounded, and the outside edges have been turned so that there is a ‘lip’ all around them to enable them to be riveted together.

.

John has even cut out the skins for the oil tank and has the whole thing clecoed together and temporarily placed in the fuselage to check the fit.  As he put it in place, it was with a sigh of relief because the whole thing simply slipped into place as if it was meant to be there!

Imagine that!

.

I’d like to share a wonderful photograph that our dedicated “Team Spirit” photographer took of the cockpit area of our Spirit of St Louis back in late 2013.  This LINK will take you to the photograph on his webpage.  You may purchase a copy of the image by clicking on the “buy” link at the top of the photograph if you would like to have your very own copy of the Spirit of St. Louis cockpit and instrument panel.
