St. Jacques Log 26 Dec 16 CB and Middle Seat

26 Dec 16:

Cut out the middle seat and attached the centerboard case. Sealed, primed and varnished some pieces.

Primed the port planks and stringers with Rust_Oleum Marine Coating wood and fiberglass primer.

Checking the plans to see where the seat sits on top of the centerboard case.

Pulled seat length and thickness off of this plan.

Picked the bevel off of the stringers and set the circular saw.

Scribed the curve.

Picked the bevel off of the stringers and set the circular saw. I cut the top board first hoping it would be long enough. It wasn't but the curve was right, so I used the first board to mark a longer boar. Cut the bevel and the curve with one pass. I'll use the first board for other seat parts.

Dry fit the centerboard case and middle seat. Drilled holes for the case log (bottom) screws and seat screws.

Sealed the bottom of the seat with Jamestown Distributors TotalBoat Wood Sealer and prepped for Gleam satin varnish. This is the first time we used the wood sealer, we got a free sample from JD and I bought the varnish to go with it. We also bought the varnish kit which came with paint pots, 10" stir sticks, paint straining filters, and 2" foam brushes. I really liked how it flowed on, nice and smooth with minimal brushing and it did a good job of sealing the wood for the varnish. The foam brushes knocked the top ridges down nicely and kept us from having drips down the side. It was nice to know that we had the right amount of sealer vs guessing on a thinned varnish approach. And we also try to stick to the same system of epoxy, paint or varnish once we get started on a project. I have to say I was impressed by the JD video and the results that Louis Sauzedde got with their varnish system. And I can't speak highly enough of how the JD technical and sales staff have supported us through a variety of phases in several projects, by phone, email and even their forum. Free shipping for VIP membership has come in handy, we just got some more silicone bronze screws with the varnish and THIXO on our last order. THIXO is ready to seal up the centerboard case.

Attached the centerboard case with Jamestown Distributors THIXO Fast Cure thickened epoxy and 6 silicone bronze screws. The screws are basically used to hold the case while the THIXO cures. I taped up the centerboard and kept it in the case during install to make sure I had the right clearance. Taped the area first to minimize epoxy spread. Peel the tape asap before epoxy cures. Don't drive to the airport and come back later expecting to peel it then....okay I did that...if that happens, get and exacto knife and cut through the epoxy along the tape edge, then peel the tape up.

Once the board was screwed in, I removed the centerboard and put in a few spacer sticks. I wrapped a few spacer sticks in plastic and dropped those through the top. Then crawled underneath to wipe out excess epoxy.

Port side primed for Oyster White. Starboard side sealed. First coat of varnish on the seat. Note the alignment sticks in the centerboard slot, I put plastic on the bottom of those so they don't get glued permanent. And yes, the centerboard case is offset to port because there is a small continuous keel under the boat. Where's Waldo?
