Bonding Fasteners in High-Density Urethane Foam

By Bruce Niederer

Many of our readers who are familiar with WEST SYSTEM® Brand epoxy products for building and repair already know the benefits of fastener bonding techniques. WEST SYSTEM® epoxy has been used in other industries for many years as well, and these folks apply knowledge and techniques developed in the marine and aerospace industries in their work. A good example is the sign industry, a huge industry in the U.S. with companies ranging from mom & pop garage operations to multimillion-dollar corporations. Continue reading

Adding Pigments to Epoxy

By Bruce Niederer

We often get asked ‘What can I use to color my epoxy?’ The intended application is as varied as our customers. Often it’s simply to make it easier to paint over or to provide a color indicator between layers. Sometimes it’s to match a particular colored material in a repair. Maybe it’s for an art or craft project. The point is, people are often looking for a color other than the black 423 Graphite, 501 White or 503 Gray Pigments offered in the WEST SYSTEM® product line. What are some options? And what are the pigment’s effects on the performance of the epoxy? Continue reading

Creating a Non-Skid Deck

By Bruce Niederer

This racing season onboard Triple Threat has been filled with the usual mix of tedium, laughs, and excitement. It’s a good thing when the exciting part is due to close racing and fast downwind surfing-it’s a bad thing if the excitement occurs when the foredeck crew nearly goes overboard because the deck is wet and the non-skid has the texture of a slip n’ slide! I’m happy to report no instances of skidding off the foredeck this year, as there had been in years past, because this year the non-skid was brand new. Continue reading

Replacing Damaged Balsa Core

By Bruce Niederer

I love my boat. I love to spend time with it-sailing it, working on it, improving it.

I think I need my head examined.

Seriously, there’s got to be something wrong with me! I actually expected that applying a new non-skid deck to TRIPLE THREAT, our 1981 Pearson Flyer, would be a fairly straightforward project. I always think like that before I get started. One would think I might know better by now, but that type of learning apparently requires some protein sequence that’s missing from my DNA.

Cover Photo: A new fleet of optimist prams were built to serve the Saginaw Bay Community Sailing Association

The Saginaw Bay Community Sailing Association (SBCSA) was founded in 1995 by a group of local sailboat racers who shared a vision of a grass roots organization to provide area youngsters and adults a low cost introduction to sailing. We began that first season with three Transfusion 547’s purchased for the association by Gougeon Brothers, Inc. (GBI) and a half dozen used Optimist prams donated by the Saginaw Bay Yacht Racing Association. Continue reading

Estimating Epoxy Amounts

Estimating Epoxy Amounts

By Bruce Niederer

This formula will help you estimate the amount of mixed epoxy needed to wet out fiberglass cloth (assuming a resin-to-fiber ratio of 50:50) and apply three rolled epoxy coats to fill the weave of the cloth, i.e. “fill coats.”

The formula includes a waste factor of approximately 15%; however, more (or less) may be needed depending on the job and personal application technique. The epoxy is applied at standard room temperature, approximately 72° F. Continue reading

“If You Were Just More Flexible”

“…you’d see things my way!”

Are flexible epoxies better than stiff epoxies? How stiff is too stiff? How flexible is too flexible?

By Bruce Niederer

Read the title of this article again. Could a statement be more confrontational? I sure didn’t think so when my ex-wife laid it on me! The issue of “flexible” vs. “stiff” epoxies seems to have become a battleground in a continuing debate among adhesive manufacturers, wooden boat builders, restorers and repair yards. Who’s right and who’s wrong? Is it even a “right or wrong” argument? Continue reading

Garbage Disposal Repair with Epoxy

By Bruce Niederer

If your kids are like mine, they manage to break stuff you didn’t even think could be broken—constantly. As parents, we can either get inventive at repairing things we know little or nothing about, or we can get second jobs and pay someone else to fix everything. I like the first option better. Continue reading

Mahogany Masters II – Morin Boat Works

By Bruce Niederer

The beauty of a wooden boat is undeniable. It doesn’t matter whether it’s sail or power. When I see one, my response is both cerebral and primal, and I know I’m not alone. I began racing sailboats in the late 1970’s and, without exception, it has always been aboard FRP production boats. In 1980, I was invited to crew on my first long distance race, hosted by the Buffalo Yacht Club near the northern end of Lake Erie. Continue reading

Plywood Boat Construction

Effects of fiber reinforcement — stiffness vs. weight

By Bruce Niederer

One of the most widely chosen materials for boat building projects is plywood. It is easy to work with, it is relatively inexpensive, and many kits and plans are specifically designed for plywood construction. Often times a fiberglass skin is laminated over the outside of the hull, primarily to provide some abrasion resistance, but also to add a measure of stiffness, because we all know stiffer is faster! And herein lies the downside: Fiberglass and epoxy add weight to the boat. How does one resolve this contradiction of strength versus weight? Continue reading
