What this video covers
Kent Blair installs a new white pine rub rail on the Alcourt sailfish Jaja using number eight silicone bronze wood screws.Watch To secure the rail to the three-quarter-inch panel, he utilizes a Fuller combination countersink and pilot bit.0:34 This tool simultaneously cuts a countersink for the screw head and drills a tapered pilot hole for the shank.0:47 Because modern wood screws often lack the traditional taper of older fasteners, he notes that specialized bits with stepped diameters for the shank and thread root are preferable when working with hardwoods like mahogany.1:20 To prevent splintering on the underside of the workpiece and protect the workbench surface, he places a sacrificial scrap of wood beneath the rail during drilling.2:17 The Fuller bit set is available through Jamestown Distributors or directly from the manufacturer.2:44 Proper pilot hole sizing prevents wood splitting when fastening trim or rub rails to small boat hulls.
