9.4.3 Upper Strake Half Installation

It was relatively easy to get the height of the bulkheads to within spec. However, the internal fuel tank baffles are another story. Because the bulkheads block the view of the baffles, you build them as close as you can based on the provided templates along with a lot of test fittings of the upper strake to make sure they arent too high! The installation process takes that into consideration. They have you mound up the Jeffco epoxy so that it squishes down when the top is put on. I wanted to get an idea of how much I’d need for each top piece, so I used some plumbers putty. I placed the putty on top at various locations, then put the strake top on to see how much each piece squished down. That gave me a good idea for how much Jeffco I’d need to place at each location.

I'm using the putty to determine how much Jeffco epoxy I need to mound up on the tops of the bulkheads and baffles for sealing the tank.

You can see the results of my experiment below.

Because the Jeffco cures so quickly, I did not have time to take photos of the mounded up epoxy at each location. Apprently the process worked, at least at the bulkhead locations since I could see squished out epoxy there. Yay!

The photo below shows the first strake top installed. Since we live in the mountains we have plenty of “free” weights available in the form of rocks to hold everything down. I used gaffers and duct tape on the leading edge to hold it into place during the cure.

The first strake top installed! There's no lack of rock "weights" available here in the mountains so I'm using those rocks to weigh down the top while the epoxy cures. The tape is used to hold down the leading edge.

There’s still strake reinforcement that needs to be completed. That’s coming up a bit later!
