It is critical that the scarf angle is set at a minimum ratio of 12:1 and that the patch thickness matches the original laminate. Matching the original thickness ensures that the stiffness will be the same as the surrounding area, reducing the chance of a crack around the repair area.\u003c\/p\u003e\n\u003cp\u003eCreating a scarf angle on the original laminate helps in many ways. It provides a substantial amount of surface area for adhesion and acts as a transition zone so that the difference in properties of the new and original laminate are not concentrated at one point. We suggest a minimum 12:1 scarf ratio between the length of the scarf and the laminate thickness. This ratio applies to both skins when repairing a cored laminate.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003e—Excerpted from \u003c\/em\u003e\u003cem\u003eCommon Errors in Fiberglass Repair\u003c\/em\u003e\u003cem\u003e by Jeff Wright, Epoxyworks 38\u003c\/em\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"content-box bg-transparent\"\u003e\n\u003ch3\u003eBeveling Fiberglass in a Transom Repair\u003c\/h3\u003e\n\u003cp\u003eThe fiberglass thickness determines the bevel length, which is also the distance from the corner to the location of the cuts for removing the fiberglass skin. As mentioned, the cut line will be located to allow the outer edge of the bevel to end before the corner of the transom. The distance of the cut line (and the bevel) back from the corner is 12 times the fiberglass thickness.\u003c\/p\u003e\n\u003cdiv class=\"columns-wrapper\"\u003e\n\u003cdiv class=\"one_third  first_column\"\u003e\n\u003cp\u003e\u003cimg class=\"alignnone size-full wp-image-2989\" src=\"https:\/\/www.westsystem.com\/app\/uploads\/2023\/06\/Beveling-Fiberglass-in-a-Transom-Repair-Illustration.png\" sizes=\"(max-width: 340px) 100vw, 340px\" srcset=\"https:\/\/www.westsystem.com\/app\/uploads\/2023\/06\/Beveling-Fiberglass-in-a-Transom-Repair-Illustration.png 340w, https:\/\/www.westsystem.com\/app\/uploads\/2023\/06\/Beveling-Fiberglass-in-a-Transom-Repair-Illustration-18x12.png 18w\" alt=\"\" width=\"340\" height=\"227\"\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cp\u003eA 12-to-1 bevel allows room for multiple layers of fiberglass fabric and epoxy across the cut line to restore strength to the fiberglass skin. If the fiberglass skin is 1\/8″ thick, the width of the bevel will be at least 1 ½” long. If the fiberglass is ¼” thick, the cut line will need to be at least 3″ in from the edge of the perimeter to allow for a 3″ bevel. If the original fiberglass skin is reused, the same bevel will eventually be required on each side of the cut after the skin is rebonded to the new core.\u003c\/p\u003e\n\u003cp\u003eLayout the cut line the required distance from the edge of the transom.
