I can’t believe it has been almost a full month since my last post. I have made progress on the boat construction even though a few competing projects have reduced my construction hours.
We are remodeling our guest bath, and even though I am not involved with the actual destruction/construction process I have been very involved with the design and selection process of bathtubs, fixtures, tile, cabinets, lights, and granite tops. We are using our trusted tradesman Jose to manage all the demolition and construction processes.
Getting back to the boat construction. I have been assembling the backbone of the boat for several weeks. The centerboard case has been covered in fiberglass.
Inside of centerboard case is epoxy sheathed with a layer of fiberglass.
I was not happy with the basic design of the centerboard pivot. While I was assured by the designer that the epoxy and glass bearing surface would not wear out I was concerned enough to make a few modifications to this section of the centerboard case. This area is sealed and cannot be easily repaired if worn out so I researched and found some carbon fiber tape that I epoxied to the inner layer of the pivot slide. Here is a picture of the area of concern and the following photo is a practice installation of the carbon fiber tape.

Sample application of Carbon Fiber Tape. I will use this on my Centerboard pivot glide.
The installation of the Carbon Fiber tape went well and I was able to finish the interior of the centerboard case with a coat of primer, and then two finished coats of graphite filled epoxy.

Once the graphite epoxy cured I laminated the two halves of the backbone together and after curing, set the now completed backbone on the bench and dry fitted the bulkheads. This is the first view that actually looks like it could be a boat someday.

I have now reached a stage where my work table has served it’s initial purpose, (construction of the backbone). I have taken the table apart and made two smaller work tables and have constructed a building frame for the next phase of construction. Here is a picture of the new building jig with the backbone held in position by two stabilizing frames located on the front and rear cross members.
