Catching up

Here are some pics from the installation of the emergency brake cables. First the pics of the cables themselves with the hardware to connect them to the brakes themselves, and then the handle.


And here is a blurry one of the end of the cable that pinches the caliper onto the rotor when the emergency brake handle is pulled. I will add another showing the linkage of the cable to the handle once the lines are run after I get the missing clamps to hold the cable in place on the frame.


The big thing I have been able to work on is the fuel tank. There is quite a bit of bench work that has to be done to re-work the universal tank that comes with the kit to make it fit into this car. I had to move the filler neck and vent holes to the other side of the tank to align with the intake neck and body. I also had to block off the old holes, and modify/shorten the arm and float that goes inside the tank to measure how much gas it contains.

Here are the before pics...



It took me 11 hours of work to get this right. The hardest part of the job was getting the screws to mate with the backing plate that had to go inside the tank. It was extremely difficult to get the screws to align perfectly, and it had to be absolutely perfect, with the plate on the inside. What made it so hard was that holding or adjusting the inside plate was very difficult. It had to be done with wire pipe cleaners inserted through the holes. Here are some finished pics, first of the blocked off orginal holes, then the new filler neck and vent tube, and last the installed fuel sender/float arm...




Many builders who went before me ran into leaking troubles with the supplied gaskets and recommended sealer. I used a sheet of cork to make my own gaskets as cork is better for fuel applications than the supplied rubber ones. And I used a product called Seal-All to surround and seal everything that might actually leak. This stuff has the consistency of airplane glue, and is not weakened by gasoline. I eventually filled the entire tank with water to completely test for leaks and it passed flawlessly.

Here is a pic of that process...

If you look carefully at the hole where the fuel sender eventually was installed, you can see that water goes all the way to the top. There was a small drip at the bottom of the hose on the filler tube neck, but it was not clamped in place yet as this was just a test and with the slightest of pressure with one finger on the rubber hose, the leak stopped, so I am completely confident that it will be fine once finished.

In the end, I did take a shortcut on the float arm. The manual says it should point one direction, but it seemed to fit fine in the direction I chose that was about 90 degrees different. The float arm points toward the front of the car instead of the driver side. But I think the clearances were fine given how much I had to shorten the float arm. If my tank eventually does not read properly how close to empty or full I am, this is going to be why.

Color scheme

I have found a picture (actually a magazine cover) online of a Cobra replica in the colors that I want for my car...



These colors are called the Gulf Oil livery. They were made famous on a different car made by Carroll Shelby that won the 24 hrs of LeMans in the late 60s. The car actually won 4 times in a row, but only twice in this color scheme. Later, Porsche raced with the same color scheme.

I do not think I will have the white circles (called meatballs) on the car. If one were to take it to the track, you could put decals on with any number you are given. That is not of primary interest for me. I just love the way it looks, and think it will be interesting to put a famous paint scheme on a car that was around then, winning races, but not like this.

On the building front, I have still been waiting for parts from Hurricane and also doing bench assembly of the fuel tank. I am just about finished with that and will be installing it soon with Nathan's help. And another post, with pictures, will be coming soon on that.
