OK, today's horror is the work being done to devise masters of the masts and the structure needed to support them over the sail. To this date I've completed a means of supporting the masts and I've built masters of the three streamlined fairings. These were the tough ones, all other masts are simple tube in section. I've taken care to design this mast support system in such a way that it can also be used to fairlead these masts for those wishing to make them operational, i.e., retractable and extendable upon either command or as a consequence of float actuation.
A means to secure the base of the many masts (two types]http://www.minitek.com/vanguard/c-021.jpg[/img]
Keep in mind that these are masters and ultimately will be realized as cast resin model parts. The top of the sail is to the left with the first and second foundation platforms next to it. To the left are the two 4-40 machine screws that hold the three-unit assembly together.
The assembled sail top and sail foundation assembly. As you can see once the sail top is permanently glued to the top of the sail, the end user will still have the ability to disassemble the foundations for adjustment or repair. It's my practice to make as many model subassemblies as accessible and removable as possible. The cutouts for the many masts have yet to be plotted and cut into the two platforms.
The three streamlined fairings wee created using the Screeding technique -- a linear draw blade, guided by the edge of the moldboard runs along the length of the table, and its specially shaped blade gives form to a mass of just mixed two-part automotive filler. What I'm doing here is forming one-half of a teardrop shape. Later, after the filler cures hard, the half-shape is popped off the board, cut in two, and the two piece glued face-to-face to form a perfectly symmetrical teardrop shaped fairing master. #### I'm good! Wax previously applied to the board kept the filler from bonding too tenaciously to the moldboard.
A closer look at the screeding operation. Previously completed filler masts have been trial fitted into the sail top. Note that one length has been turned into a specialized sanding tool by gluing a strip of #400 sandpaper to its end.

Thats all for today folks. More to come. You'll see this puppy at Regatta 2006...
