Fiber Reinforcing Tapes

By J.R. Watson

Composites are a blend of resin (in this case mixed epoxy) and reinforcing fiber. Folks often ask, “How strong are they?” It is difficult to answer this question due to many variables including resin type, fiber type, fiber orientation, and resin/fiber ratio. To give a value for a laminate, we reduce the variables. Values shown in this article were done with test samples using WEST SYSTEM 105 Epoxy Resin®/206 Slow Hardener® at room temperature (70°F). Reinforcing fibers are Episize™ materials. Laminates made for the test had fibers oriented in one direction (unidirectional) and were laminated using Continue reading

The Glenn Curtiss Museum

By Michael Barker

Glenn Curtiss is recognized as the “Father of Naval Aviation.”He trained the first Navy pilots and built their first aircraft, the A-1 Triad Amphibian. It was “Curtiss Pushers” in 1910 and 1911, that demonstrated capability to take off and land on a ship, leading to the development of aircraft carriers. Continue reading

Six10 Epoxy Adhesive

WEST SYSTEM Introduces Six10

At two-part adhesive in a convenient, self-metering cartridge for permanent, waterproof structural gap filling and gluing.

Six10® Adhesive gives you the strength and reliability of a two-part WEST SYSTEM epoxy with the convenience of a single part product. Six10 is dispensed with a standard caulking gun. Non-sagging Six10 bonds tenaciously to wood, metals, fiberglass and concrete. It cures in temperatures as low as 50°F. Working time is 42 minutes at 72°F. Cures to a solid in 5–6 hours and will take high loads in 24 hours. Cure time is faster at warm temperatures and Continue reading

Gougeon 12.3 canoes

The Gougeon 12.3 Canoe

Epoxyworks 29

Cover Photo: A small sampling of the Gougeon 12.3 canoe family. Robert Monroe’s cold-molded canoe (foreground) came from a half-mold that eventually resulted in the a 12.3 mold (object directly behind first canoe) which has been used since 1989 to produce dozens of offspring that reflect a wide raged of tastes and technology.

The Gougeon 12.3 canoe represents several decades of experimentation by employees of Gougeon Brothers. Dozens have been built but no two are exactly alike. The evolution of the Gougeon 12.3 parallels our love of boating, passion for innovation and desire to build better boats—all of which contribute to the products we produce today.

It started 35 years ago with a personal project of Jim Gardiner, who was an employee of Gougeon Brothers at the time. He wanted to build the lightest solo canoe possible  Continue reading

Turning a Gougeon 12.3 into a Kayak

BY TOM PAWLAK

I recently modified the deck of my wife Mary’s fiberglass canoe (one of dozens built from the Gougeon 12.3 mold) to make it more seaworthy and to facilitate a spray skirt. More like a kayak. Previously, the decks covered only the ends of the boat leaving the middle 40% wide open. I’m fairly pleased with how it turned out. Continue reading

Six10 Epoxy Adhesive

Understanding Six10 Epoxy Adhesive Properties

By Jeff Wright

WEST SYSTEM® Six10 is a two-part, pre-thickened epoxy adhesive formulated with properties that make it perfect for many adhesive applications. Compared to other ready-to-dispense adhesives, its particular physical properties make it ideal for stitch and glue boat construction, fiberglass laminate repair and general bonding. This new formulation has a good balance between the elongation and toughness of G/flex® and the strength and stiffness of our 105 Resin-based epoxies. You can use it with as many materials as possible including wood, metals and composites. The long working time with fast thru-cure and unique shear thinning are additional characteristics formulated into Six10 that contribute to its ease of use. Continue reading

Practical Tips for Using Six10

By J.R. Watson

The WEST SYSTEM® Six10 cartridge is comprised of the cartridge body, removable nose plug and a threaded retaining nut. A 600 static mixer is included with the cartridge. (It’s called a static mixer because it has no moving parts.) The cartridge fits into any standard caulk gun—manual, cordless or pneumatic—and allows simultaneous dispensing and mixing of the two-part epoxy. Manual caulking guns are graded by mechanical advantage (MA) in relation between the travel of the pistol grip and the plunger. When using he static mixer, resistance Continue reading

Kayak Lessons Learned

By Captain James R. Watson

Kayaks are versatile craft. I’m a lucky guy who has had decades of pleasure cruising, exploring, fishing and simply relaxing on many different streams and lakes throughout Michigan and Canada in my stripper. Comparing the investment dollar per pleasure derived, my kayak wins hands down over all the other water craft I’ve owned. In her wake I’ve been taught many lessons, albeit some the hard way. Here are a few I thought worth sharing. Continue reading

The wet winter months in Oregon are perfect for garage projects like boat building and car restoration. They are less than “ideal,” however, if you want a perfect epoxy finish for your boat and your garage is unheated. Continue reading

James Wharram Designs

By J.R. Watson For many decades Gougeon Brothers Inc. has kept in contact with multihull designer James Wharram. Wharram, of Cornwall, UK, has sailed and designed Polynesian-style catamarans for 50 years. Amateurs and professionals have built his boats and sailed them to all corners of the planet. The designs he creates with his engineer and artist partner Hanneke Boon have evolved over the years, but remain unmistakably, Wharram Catamarans.
