Ion

By Captain James R. Watson

I wanted an efficient, modest, contemporary and quiet running yacht for cruising the Intra coastal waterway, Chesapeake Bay, Bahamas and the Great Lakes in my retirement. The boat would require the ability to safely cross several hundred miles of open sea at a good cruising speed. Continue reading

Build What You Can’t Buy

By J.R. Watson

Do you sometimes need a replacement part for your boat, home or recreational vehicle and find out its no longer available? Discontinued. Source unknown. Can’t be found. Maybe the price borders on insanity or, you need a part that simply does not exist and never did.

“Okay,” you say, “I need it, can’t get it, my only option is to make it.”

As soon as you reach this decision, two thoughts pass through your mind. “How will I make it?” and “What materials shall I use?” You may have a third question like, “Am I the only one that has these problems?” Continue reading

Saving Your 801 Roller Frame

By J.R. Watson

When you’ve completed a coating task using a 801 Roller Frame and 800 Roller Cover, what next? The roller frame is reusable. But if you leave it resting in the pan while the residual epoxy cures, you‘ll probably ruin both the reusable pan and the roller frame. If you lay the roller and frame on a work bench, it will be stuck there the next day.

Setting the roller on a piece of plastic will bring you closer to success but in any instance where the roller frame rests on a surface while the epoxy cures, the cover will accumulate Continue reading

Using G/5 Five Minute Adhesive

G/5 Uses and Tips

By Tom Pawlak and J.R. Watson

Spot prime metals with G/5 in place of slower drying paint primers for indoor applications prior to applying latex paints. Latex paint can be applied to G/5 about ten minutes after the epoxy is applied and while the epoxy is still soft. G/5 provides a thin barrier and prevents rust that otherwise forms in latex paint when it dries over bare steel.

Model railroad set builders create natural looking surfaces by applying a film of G/5 adhesive and then sprinkling small objects onto the surface while it is still uncured. These Continue reading

Reinforcing Fiber Tapes

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

Six10 Thickened Epoxy Adhesive

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

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.

How to Build a Set of Planer Boards

By J.R. Watson

Planer boards allow for more fishing lines to be trolled simultaneously and are used to spread lures and harnesses away from the boat when trolling at low speeds (below 2 knots). They are commonly used when fishing for walleye. You can achieve a greater dimensional spread with planer boards than with outriggers. Continue reading

Revisiting a Church Window Restoration

By J.R. Watson

Those working on projects that use epoxy for restoration and rot repair often ask, “How long will this last? Will the rot return?” At Gougeon Brothers, Inc., we have lots of in-house test approaches that can analyze tension, compression, shear, and fatigue. We can also predict the consequences of ultra-violet, arid, tropical, and cold conditions. Still, there’s nothing like real-world performance over time. Continue reading

Lost foam method

Fabricating an Air Scoop

BY BRIAN KNIGHT & J.R. WATSON

I used lost foam construction to fabricate a fiberglass air scoop for my son’s Formula Continental C race car. Our project started because a modification to the shape of the race car body necessitated the construction of a new air scoop. The air scoop is bolted to the car body so if either the air scoop or the body is damaged (a very likely scenario), the repair will be simpler. To fabricate the scoop, I made a Styrofoam male mold, surrounded the mold with fiberglass, and then dissolved the Styrofoam to leave a hollow part. I used Styrofoam to build Continue reading
