1963 Alcort Sunfish CHIP 10 Apr 19 Scarfs and Keel Strips

10 Apr 19:

Worked on the bottom panels and keel strip for CHIP. For an 8:1 scarf on 1/4 inch plywood mark a 2 inch scarf line (8 x .25 = 2). The end of the panel is then planed to a slope, with a feather edge on the end up to full thickness at the 2 inch line. And since we want this stern panel scarf to fit underneath the bow panel scarf, we cut the scarf on the top face of the panel as we look at it. For the bow panel, we cut the scarf on the underside face.


120 grit belt on a Black and Decker belt sander a Stanley #5 jack plane to cut the scarfs into the 4 bottom panels. We lined them up on the 2 inch marks and cut the slope, looking for the ply glue lines as we shaved wood away. The goal is to get them as evenly spaced as possible, with the big picture being that the panels are being glued together. and no one will see that part while you are hiking out.


Cut 3/4 inch bottom panel centering strips from pine on the Ryobi table saw. They are sized to fit in the center notch on the keel strip centering jig. The weathered piece above the calipers is the old keel strip, used as a guide to find measurements for the centering strips and new keel strips. The strips are in two pieces, one to fit ahead of the daggerboard and one behind, and that means they can also be cut from an 8 foot piece of lumber. In ohter news Push Stick v1.0 is holding up pretty well.


Attached centering strips temporarily with #10 silicone bronze screws, drilled the pilot hole with a Fuller combination pilot hole and countersink bit. Those bits are tapered and work well for the softer silicone bronze screws, the same ones we'll use to permanently attach the keel strip. Bottom panels will be fit, glued and nailed, then centering strips come out and permanent keel strips wit overlapping edge attached. And the Kobalt drill and impact driver have held up well, we especially like the impact driver to put these screws in. Battery life has been great for our projects.


Attached centering strips temporarily, panels will be fit, glued and nailed, then centering strips come out and permanent keel strips wit overlapping edge attached. Keel strip is on the left, you can barely make out the T shape where the strip will nestle between and overlap the panels.

Fuller Countersink Set #8

We use these a lot on our wooden boats along with silicone bronze wood screws.

"The Fuller #8 Countersink Set contains five type C countersinks for wood screw sizes #6, 8, 10, 12, and 14 with 3/8" and 1/2" cutting diameters. Five matching taper point drills, 3/8" and 1/2" stop collars, 3/8" and 1/2" plug cutters, and two hex keys are all included in a really nice-looking mahogany case.
Fuller countersinks will last a lifetime if taken care of. The number 8 is our most popular set, favored by wooden boat builders, woodworkers, and other craftsmen."
