    I'm going to add some braces on the sides to stiffen up those areas . . .

    First I cut & shaped the foam core pieces.

    Then I covered them with 1708 cloth. Here they are after curing, but still needing a bit of trimming.

    I'll tab these into the sides with more 1708.

    I am traveling the next couple of weeks, so I won’t be back at it until Memorial Day weekend.

    Remaining work is:

    Aft area
    Pylon stiffeners
    A few touch-up spots

    Then, I will be ‘popping’ the platform out of the mold.

    Targeting to be done/installed mid-June.

    A friendly tip...stainless steel luvs to gall. Despite the issues with grease in the fabrication area, make sure and grease the bolts if you are putting nuts on them.

    I had one of four of my hardware connections on a project fail and it took an hour to remove and the bolt basically came apart due to the galling.

    I had told myself I was going to lube the connections immediately after my glasswork. Fail. Fortunately, the rivnut installation (female side) was so tough, I was able to simply tap it and while less thread, still enough to avoid removing the rivnut.

    Galling. . . I had to Google that.

    A definite yes on the grease, as it will be salt water exposure, which will add its own challenges.

    Gelcoat won't get a stress fracture.
