I’ve been working on installing deck hardware and just finished with the sliding hatch and sliding hatch cleats. The hatch itself had to be cut out neatly using a router and cutting wheel and fit to the deck so that it slides well and the there is no interference. When everything is how I like it, the carbon underside is coated with waxed resin to create a nice finished surface. After that cures I can add the teak handrail to the top. The installation is setting this hatch on the deck and adding cleats to keep it in place.
These cleats are also teak and have eight counter bored holes for bolts. I also add a small chamfer to the underside of the bolt hole. This ensures that the hole is sealed properly because the compound fills this area up.
After dry fitting the cleat, it is taped off, removed, compound is put down, and the cleat is then installed. After the compound cures, I will trim it with a razor and pull the tape, making a nice crisp line.
