Installation of the deck continued today with the starboard side deck panel. As with the larger deck panels, this one was coated with unthickened epoxy on its under side (although it conceivably have been done later, as there is access to it after installation, in contrast to the deck over the bow and stern compartments. The sheerclamp and carlins mating surfaces were then coated with mustard thickened epoxy. The deck panel was then positioned in place, and ring nails driven every 3 inches along the planed sheerclamp. Along the carlin, clamps were placed to hold the panel tight at that joint. As the nails reached the stern, I cut the panel with a sharp utility knife, using the overlapped panel as a position guide. Several passes of the knife were required to cut through the thickness of the deck. Once cut, the overlapped segment is removed and the deck will then lay flat, producing a tight butt joint. Underneath this deck butt joint, a reinforcing butt plate is epoxied in place with cabo-sil thickened mustard epoxy. I used an arrangement of pipe clamps and bar clamps to hold the plate tightly in place. The epoxy was then allowed to cure overnight. Total time 35.00.

Starboard Deck Panel

JCH at CLC saves the day with his CNC
The first big goof in building the Mill Creek 16.5 became apparent yesterday as I test fit the side deck panels. After having tested them prior to permanently installing the bow deck, I now found that my haphazard placement of the bow deck left a gap between it and the aft deck panel that was too large to be spanned by the precut center/side panel. The precut parts are cut with excess material to allow trimming to an exact fit, but I used up all that buffer by moving the bow deck panel too far forward. The error left about a quarter inch gap that needed to be spanned. Since I plan to give the deck a bright, or varnished finish, filling the gap with an additional scrap of wood or even peanutbutter epoxy would have been unacceptably unsightly. I had first resolved to order another sheet of okoume plywood and cut replacement parts myself, making them just a bit longer. However, the fine folks at Chesapeake Light Craft helpfully offered to cut a custom panel with the needed extra length. This will be much cheaper than purchasing and shipping an entire sheet of plywood! Thanks CLC!

Foredeck
Deck installation continued with the foredeck. This process was the same as previously described with the aft deck, except that the foredeck is significantly larger. It also must be worked into a sharper curve than the aft deck; the radius of the deck is 24" at the deck beam, compared to 30" in the aft section. To hold the deck in place, I applied a rachet strap at the location of the deck beam. I also used several spring clamps to hold it along the border of the cockpit at the carlins. Nailing along the sheerclamps every 3", and alternating sides every 4 nails or so eventually worked the deck into place. I found that my original positioning was a bit off, and the port side near the bow almost didn't cover the sheerclamp- put it came out flush, and will merely eliminate the need for much trimming in that area. Total hours 34.00.
