Alcort Super Sailfish ZSA ZSA 21 Nov 18 Backer Block and Bottom Panel

21 Nov 18:

Someone added a splashguard to ZSA ZSA at one point, just screwed it into the 1/4 inch deck. It's not going to keep out much water but Skipper thinks it might make a good thing to hold on to or brace a foot against, so we are keeping it. While the bottom is off we added backer blocks to seat screws into, fastened with TotalBoat thickened epoxy (THIXO). We held it down while the epoxy dried with a can of primer.




Fastened the first bottom panel with TotalBoat thickened epoxy (THIXO). It is best to put epoxy or glue on both work surfaces for best coverage, the product soaks in a bit. We also took a small piece of paint stick and spread the THIXO out a bit. When the panel is sealed, very small amounts of epoxy should squeeze out of the seam, that is enough pressure and enough epoxy for a perfect joint.


Fastened the first bottom panel with TotalBoat thickened epoxy (THIXO), ready for silicone bronze ring shank nails, the wood fibers lock back onto the rings and resist withdrawal. We use a small drill pilot to get a pilot hole for the nail through the plywood.


Made a marking gauge to mark the nailing line and nail spacing, hammered in silicone bronze ring shank nails every 2 inches. The gauge is placed against the side of the boat and is notched because the edge of the plywood panel has not been trimmed yet and overhangs the side a bit. We will trim that off once the panels are all fastened.


Made a marking gauge to mark the nailing line 1/4 inch in from the side, marked the line with a pencil.


Drilled pilot holes for the nails every 2 inches using the gauge as a guide, hammered in silicone bronze ring shank nails, set them just below the surface. Putty to follow.
