Cosa tratta questo video
Louis Sauzedde demonstrates how to cut progressive bevels on a bandsaw — a technique required when building boat molds that are cut to bevel rather than left square-edged.▶ 0:05 Because ship saws (purpose-built for progressive beveling) are no longer manufactured, Sauzedde modified a Powermatic bandsaw by adding a lever arm to the table, allowing the table angle to be adjusted continuously while a cut is in progress.▶ 0:05 A two-person method is used: Sauzedde calls out the degree increments while his partner Tom adjusts the table to match.▶ 1:01 The first demonstration cut runs a straight line from 5 to 10 degrees — a 5-degree progression.▶ 1:00 The second cut follows a curved line from 0 to 10 degrees, closer to what actual mold-cutting requires.▶ 3:20 Both cuts succeed cleanly.▶ 5:00 Sauzedde notes that real mold work will not demand progressions as steep as 10 degrees, so the saw's capability is confirmed as sufficient.▶ 5:27 Cutting molds to bevel rather than square takes more effort but produces a cleaner result.▶ 3:26
