Bunkers and Compression post base

İ finally glassed the front bunks.

İ cutted large fiber panels and layed them from starboard to port, perpendicular to the carbon fiber İ had already used to reinforce the bottom hull seam. This will give me additional strength at the bottom of the hull.

Just before glassing İ also used fairing filler to round off the bunks edges. Took a little while to get it right but it was worth the effort. The fiber cloth wrapped nicely around those curvy angles.

Then İ moved on to the compression post base.
Not much to say about those except that İ opted for a pyramid of two blocks, glued together, and to the hull and frame, with microfibers. (The picture below shows some rough fairing filler which was then nicely sanded)



The bottom one goes from port bunk stringer to star bunk stringer. İt will help in distributing the forces on the compression mast to the whole stringer structure which was itself reinforced with kevlar.
For the upper block İ switched the grain orientation and it is placed grain up. The base of the compression post will be screwed onto this block.
And last, in order to minimize frictions and wear of F89, İ wrapped it around with a 1 mm alu sheet. So İ will have alu rubbing on alu. We will see how that works.
