Instead of painting the lines on the deck, I went for the caulked deck,
I used a V block to clean up the edges of the strips on the deck and masked off everything except the grooves. The tape I used along the groove edges was 3M Fine Line tape which is plastic and gives a very clean edge. Regular crepe masking tape was used to protect the balance of the finished wood. Sikaflex has a polyurethane product for this application but at over $10 per cartridge I decided to go to the hardware store and used a white exterior polyurethane for window and door edges that is rated for 50 years (good enough for me). Using a caulking gun I filled the grooves and smoothed them with a plastic spoon so the compound is just below the top surface of the deck It turned out pretty well overall but polyurethane compounds like this take a week to fully cure and they remain tacky for about a day. I have a few spots where air was trapped beneath the compound and once it began to set I noticed some bulges and bubbles forcing some of the compound to rise above the deck. This is something I might fix later but in the bright sunlight it is hard to notice. The covering boards are made up of three pieces which I stained to a uniform color that is darker than the rest of the boat but not so dark as to muddy the grain. The joints are visible in some of these pictures. I made the cutwater and transom edging from 18 gauge stainless, which is a pain in the neck to cut but some good jigsaw blades, cutting oil and perseverance eventually paid off. I used 1/16" plywood to make templates for all pieces then cut, polished and drilled the transom edges. The cutwater was a little tricky but I started with the two pieces, which I fit (bent) to go along with the contour of the stem making sure that they met in a straight line. I taped them together and ran a weld bead on the outside to join them. I coated the outside surfaces with flux to protect them from the welding splatter. This left some grinding work and a lot of polishing but it came out fine. There was some minor fitting after welding where sections of the cutwater had to be spread open since the heat from the welding process tended to make the metal shrink (I guess). I hope these comments and photos are of help to other builders. |
