WOW – A Homebuilt Glen-L Riviera

By Mike Barnard

Cover Photo: WOW, a 20′ Glen-L Riviera built by Mark Bronkalla

In June of 2000, Mark Bronkalla launched his homebuilt Glen-L Riviera. The20′ runabout was nearly complete but not yet named. The boat turned heads wherever Mark took it and the reaction from bystanders was a universal “WOW.” That’s how his beautiful Glen-L Riviera got its name.

Mark had never built a boat before and found lackluster information from first-time boat builders like himself. Websites or blogs with good information tended to end once the structure was built. Mark used his background in woodworking, marketing, and computer science to share his first-time boat-building experience to encourage and help other first-time boat builders. In this article, I’ll give a brief overview of this build where WEST SYSTEM® Epoxy was used. Anyone considering a build similar to this should consult Mark’s website, bronkalla.com, for more detailed descriptions of each step. Continue reading →

Marquetry: Fake It Until You Can Make It

By Don Gutzmer – GBI Technical Advisor

Wood inlay marquetry has been around for a very long time, and I am always looking for different ways to use epoxy. I have learned that it is possible to use a laser jet printer with a clear transparency film to print an image, then transfer that image onto a substrate coated with WEST SYSTEM Epoxy, resulting in the look of marquetry without all the cutting, fitting and craftsmanship. (Inkjet printers do not work with this process because the ink does not transfer to the transparency film.) The image could be a picture of a wood inlay or whatever you can imagine. Here is the process I have found that works the best. Continue reading →

G/flex Does It

By Hugh Horton

The project was creating a shower pan for an Americans with Disabilities Act (ADA) bathroom in the home I’ve been building in Cedar Key. How does one satisfy shower pan requirements of Levy County Florida and meet ADA suggestions, too, when the floor is concrete, twelve feet above ground? Continue reading →

Big Red Gets His Smile Back

By Tom Pawlak — GBI Technical Advisor

My neighbor Rollie is always coming up with these unbelievable deals along the highway between his home in Bay City, Michigan, and his cabin a couple hours north. The latest super deal was a big red garden tractor that was mechanically in near perfect working order—except the previous owner ran it into something and busted up the grille. He brought it over and asked if it could be fixed. Here’s how we repaired the broken grille on “Big Red.” Continue reading →

An Outdoor Ceiling Fan Support Crane

By Douglas Heckrotte

I first saw outdoor ceiling fans while vacationing on Isla Mujeres, Mexico, just north of Cancun. These fans are ubiquitous and evidently inexpensive. Used both indoors and outdoors, they’re mounted on 3″x 3″ concrete beams. Some of those beams also support sun shades but usually, the fans are completely open to the weather. Continue reading →

Boats as Art: The Sculptures of Larry Brown

As a career architect-sculptor, Larry Brown created a vocabulary of freeform shapes that bring a sense of naturally flowing, organic dimensionality to his art. Recently, he applied his methods to a municipal scale art project using recycled fiberglass boats. His goal was to make large fine art pieces and park scale sculptures. Continue reading →

Azek® PVC Deck Boards

An option in boat construction or repair?

By Bruce Niederer — GBI Technical Advisor

Wood has always been used in fiberglass boat construction, in stringers, and oftentimes as core in high compression areas such as under cleats, stanchions, and winches. Wood works great in these applications but we all know that the big problem with wood is the fact that it rots if it gets wet. Here at Gougeon Brothers, Inc. (GBI), we have spent long hours writing manuals and training people to use proper techniques using epoxy to keep wood dry and strong. Continue reading →

Hog Tide Deck Repair

By Greg Bull — GBI Technical Advisor

Hog Tide’s deck was spongy around the chainplates, so I decided to fix the core in the deck. Because the main bulkhead was being replaced, it made it easier to do the deck repair from the underside. I started by removing the inner laminate to get to the bad core. I determined the extent of the bad core by tapping on the laminate; a duller sound suggests deteriorated core. Another way of determining if the core is bad is to drill small holes to see where the bad core is by noticing if the balsa core is a dark color. Water may even drip from the drilled holes. To cut the inner laminate I used a high-speed oscillating cutter with a diamond grit blade (multitool). When cutting out the inner laminate, keep the area that is being opened up as small as possible. You can always make more cuts to make the area larger. Continue reading →

Composite Materials Merit Badge

By Tom Dragone, PhD

In Epoxyworks #38, we published an article featuring two projects that met the requirements for the Boy Scout’s Composite Materials Merit Badge. Here, Tom Dragone tells us about two more projects completed by scouts in Troop 7369 from Chantilly, Virginia.

In 2006, the Boy Scouts of America created the Composite Materials merit badge for scouts to earn, to help them learn about the importance of composite materials and encourage them to consider careers in this field. Being an aerospace composites engineer as well as an active scouting advisor, I saw this as a natural opportunity to share my interest and experience in composite materials with the scouts in my troop. I developed a set of projects to help the scouts learn about composite materials and share them in the hope of getting more young men interested in this exciting field. Continue reading →

Adagio

Still Formidable after 46 Years

By Ben Gougeon

Adagio, our beloved trimaran, was designed and built by Meade and Jan Gougeon in 1969 and launched in the summer of 1970. After undergoing a minor refit this past winter, she still has what it takes to win. We’re extremely proud that Adagio placed first in the multihull division of 2016 Bell’s Beer Bayview Mackinac Race, which spans almost 300 miles of often treacherous Great Lakes. Continue reading →
