Seating the Reinforcement Blocks (for the Mast Track Finboxes)

I got these in place last night.  Not too much drama.

Straight epoxy with a layer of carbon on the bottom.  Epoxy mixed with milled fibers spread on the sides of the blocks - then inserted in the holes.

Epoxy mixed with cabosil to fill in the gaps across the top and in the sides of the blocks.

Next is routing out the slots for the boxes.
