To prevent this, seal the edges of the wood with a thin layer of epoxy and let it reach the tacky stage before pouring epoxy into the cavity.

MODERN DECKED SAILING CANOES By Hugh Horton Using epoxy with wood and modern high modulus fibers,the homebuilder can create light and strong evolutions of the sailing canoes designed by the Scot, John McGregor,in the 1860’s. Modern decked sailing canoes are simple, efficient, solo craft which are equally proficient under sail or double-bladed paddle. Puffin and Serendipity,for example, are 15′ long with a CALCULATING EPOXY FOR FIBERGLASS LAMINATES Here is the formula to calculate all of the glass for the new laminate schedule. I am putting together the segments we used earlier for quick calculation. 79 sq. ft. ÷ 9 = 8.77 sq. yd. 8.77 sq. yd. × 22 oz = 192.04 oz. 192.04 oz. ÷ 16 = 12.59 lb. of 738 Episize Biaxial Fabric. FIBERGLASS REMOVAL TECHNIQUES By Tom Pawlak Occasionally we receive calls from people who want to remove fiberglass cloth from wooden structures. The fiberglass on the bottom of a stripper canoe has worn out or the fiberglass and polyester on the deck of an older wooden sailboat has delaminated. The techniques described here work well for removing 1 or BONDING WITH EPOXY FILLETS 2. Apply and shape the fillet. 3. clean away excess epoxy outside the fillet. If wood components have not previously been sealed in epoxy, it is good practice to apply a thin coat of epoxy to saturate the surface prior to applying the thickened epoxy fillet so the edges of the fillet don’t soak into the dry wood and cause a dry edge.

Plywood typically comes in an odd number of plies in order to achieve balanced construction.

The plies should be parallel to one another with POLYESTER OVER EPOXY By Jeff Wright Most production fiberglass boats are made with polyester resin. WEST SYSTEM® epoxy is a wonderful material for repairing polyester fiberglass boats. One reason for this is the ability of epoxy to form a stronger mechanical bond to a damaged laminate than polyester resin.

Adhesion failure in the repair laminate is the most common failure mode for fiberglass repairs. To ensure good adhesion it is critical that the repair patch is adhered to undamaged laminate.

HOW TO GET EPOXY OFF YOUR CLOTHES First, place a piece of plywood behind the stained area, apply a dab of waterless skin cleanser to the spot, and scrape with a coin. Repeat four or five times. Then scrub with dish soap and a stiff fingernail brush. If there is still epoxy in the fabric, it will usually show upas a white spot.
SHARP FIBERGLASS CORNERS Apply fiberglass cloth to the first side of the corner, letting it extend slightly past the corner. Allow it to gel. When it is at a flexible leathery stage, use a sharp utility knife to trim the material extending past the corner. Then apply the glass to the other surface in the same way. Apply the build-up coats to the glass andfinish normally.

JON STAUDACHER’S APPROACH TO PROJECTS BY DON GUTZMER – GBI TECHNICAL ADVISOR Cover photo: THE ANIMAL alongside one of Jon Staudacher’s other projects, an acrobatic airplane. Photo by Avram Golden. My good friend and previous employer, Jon Staudacher, always surprises me with how he designs and builds his projects. Jon creates everything from hydroplanes to airplanes using materials and methods that are logical and practical. He would say he treats most of the things he builds like a science project, experimenting with new concepts in design and materials, and continually learning new things. I will explain some of Jon’s unique approaches to a few of his recent projects. Continue reading → This entry was posted in Aircraft, Multihull

QUALITY CONTROL: IT’S WHAT WE DO _BY PAT DAMMER – GBI LAB TECHNICIAN_ At Gougeon Brothers Inc., customer service and support are paramount. Throughout the decades (five strong and counting), we’ve built our WEST SYSTEM® product line on a model that places customer satisfaction at the forefront. Many WEST SYSTEM users know first-hand that we strive for customer success no matter the project. Our customers’ projects range across an extremely wide spectrum. What many users may not know is the extent of product support that grinds away behind the scenes before a batch of our epoxy even hits the retail shelves. I’ll provide a look at just one of our churning gears that isn’t so obvious at first glance-quality control (QC). Continue reading → This entry was posted in Epoxy Products,

SURVIVING FLICKA’S CAPSIZE, PART 2 _On June 20, 1979, while sailing in a qualifying race for the OSTAR (Original Single-Handed Transatlantic Race), Jan Gougeon’s self-designed and built 31′ trimaran FLICKA was capsized by heavy seas in the North Atlantic. Jan survived on the overturned plywood/epoxy multihull for four days before he was rescued by a passing freighter. The following is the second half of a transcript of a phone call between Jan, his brothers Meade and Joel, as well as fellow multihull designer/sailor Mike Zuteck. Their discussion takes place on June 26, 1979, just hours after the freighter that rescued Jan delivered him to dry land. Part 1 of this conversation can befound here.

CARBON SKINNING
_BY JEFF MCAFFER_
It all started when I got a new 360-degree camera for my racecar. Mounted on the dash, it captures a really cool perspective that allows viewers to see forward, watch cars as I pass them, and to see what I’m doing (check it out at youtube.com/user/jeffmcaffer). Unfortunately, the dash produced considerable glare on the windshield. As you can see in the photo, it also had various holes and divots that were not useful in a racecar such as a coin tray, air conditioning vents, and extra switch panels. I wanted to fill those in. But how? Continue reading → This entry was posted in Automotive, Carbon

MAKING KNIVES WITH G/FLEX_By Jared Kramer_
G/flex® Epoxy is the adhesive I use almost exclusively for making knives. Years ago, I found out about G/flex from other knife makers. After reading about its properties compared to standard epoxies, I realized it suited my needs just about perfectly. A marine epoxy like the WEST SYSTEM® 105 Resin system is incredibly durable and would likely outlast my lifetime on most knives. However, the “flex” is the main reason I use G/flex instead.

CHOOSING THE RIGHT WOOD FOR YOUR BOAT REPAIR WHY PRESSURE-TREATED PLYWOOD IS A POOR CHOICE _BY TERRY MONVILLE – GBI TECHNICAL ADVISOR_ A very high percentage of boats in the U.S. are at least 30 years old. It doesn’t surprise me when a boat’s plywood components fail due to water intrusion. In my experience, the transom is the first area to rot out in most trailerable boats. That’s not to say the first thing to rot couldn’t be the cockpit floor, stringers, or motor mounts. Continue reading → This entry was posted in Boat Repair,

GAFF REPAIR
_BY BILL BAUER_
In preparation for a thorough Coast Guard inspection, we’d stripped the masts, booms, and gaffs on the schooners Appledore IV and V of paint and varnish. This revealed several small rot areas, wear, and damage. Two of the gaff jaws (also called gaff saddles) had significant damage, including cracks in the jaws themselves, probably due to hard jibes and insufficient repairs. Gaffs are the angled spars from which the sails are hung. Continue reading → This entry was posted in Boat Repairand

THICKENED EPOXY APPLICATION_BY MIKE LENEMEN_
My idea for this thickened epoxy application method was borrowed from my grandfather, a notable oil painter. What I remember the most about him is how he painted. He used standard oil paints but did not use a brush. Instead, he painted with cake decorating cones and his fingers. One day, when I was working on applying some thickened WEST SYSTEM_®_ Epoxy , I had an epiphany: my grandfather used cake-decorating cones to “draw” with oil paints and he was very accurate with them… maybe that would work with thickened epoxy. It has about the same consistency (viscosity) as oil paints. Continuereading →
