Cutting & Forming
Straight Cuts: For best results use a table saw with a carbide blade (50-70 teeth) at approximately 1200 rpm.
Curved Cuts: A Jig saw with a wood cutting blade is great for curved cuts (some sanding may be required)
When sanding Marine Lumber use an orbital sander with 120 grit sandpaper
By far the best way to finish the edges after the cut is with a router, using a 1/2" carbide bit with at least 2 flutes.
Clamp Marine Lumber on a workbench with the end you want to bend overhanging the edge.
Pass a heat gun back and forth while bending the Marine Lumber down.
For a tighter bend, cut a V where the inside of the bend is going to be with a 3/4” (90º) V bit to a depth of 3/8”.
Secure the board firmly in a bench vise, or clamp to the work table.
Using a heat gun on low setting apply heat evenly to the seam, while applying pressure to bend.
Let the joint cool and you have a perfect 90º waterproof corner.
