Over the last few days, the 5mm (or is it 6mm? - can't remember) plywood has been laid over the deck planking.
A fairly time consuming task with the shape of each panel being modified until a fag-paper fit is obtained with adjacent structures. There are 14 panels to be done, for each the process is the same. First the deck planking is "wetted out" with un-thickened epoxy, followed by the plywood panel - making sure the edges are well saturated.
Then batches of thickened epoxy are made up and spread over the wetted out deck planking with a notched scraper. Working as quickly as possible in this heat and trying to use the coolest part of the day first thing in the morning, otherwise the 1st section applied is already going off by the time you get to apply the panel. This will mean limited squeeze-out of excess epoxy, but more importantly leave voids under the ply leading to rot potential.
The ply panel is laid onto the deck and pushed home against adjacent objects i.e. cabin side or neighbouring panel. Then using the nylon brads and pneumatic nail gun, an edge is secured at about 1 to 1.5 inches intervals. Then working towards the outside edge of the deck, a grid pattern of nails at about 2" pitch are driven in, hopefully generating a wave of excess epoxy under the advancing front of secured plywood, until the edge of the boat is reached (and it oozes out all over the floor...). Hopefully this means there will be no air pockets trapped underneath and the surface will be uniform and smooth.
It is only really possible to do one panel at a time - each previous one needing to be cleaned up before the epoxy gets too hard and to making sure that a clean joint can be made between the next panel.
By the end of the week all but the 1st panel at the bow - which has a lot of curvature and is being clamped down for a couple of weeks to induce some bend and a couple of little strips by the aft sheetman's hatch, are fixed.
When these are fitted, the next task is to fair all the sunken nail heads and any undulations that may be present at the panel joints, ready for the application of the glass mat.
However, the main reason for doing this at this stage is to cut the hole for the rudder tube. This will allow me to determine the exact final depth of the tube from the underside of the hog to the top of the boss that sits on the deck and allow the fabricator of the rudder assembly to machine the bronze tiller casting I had done some months ago, so the two mate together without either binding or being too high off the deck...
