White Oak Redux

White Oak Redux

BY BRUCE NIEDERER AND BILL BERTELSEN

Building stuff, especially boats, with wood is much like a religious calling; once you hear the call, there’s no turning back. Those who’ve heard the call will not suffer fools willingly, so when I decided to conduct some white oak adhesion and shear testing and report the results in Epoxyworks 31, skeptics and believers alike took to the internet wooden boat forums-and had no problem speaking their minds! Having healed from the pummeling I took in some quarters, I’m back again to report the promised follow-up test results. Continue reading

Of Applecores and Deadeyes

By Bruce Niederer and Bill Bertelsen

Gougeon Brothers, Inc. has supported our local tallships—Appledore IV and Appledore V—since they arrived at their downtown Bay City facilities on the Saginaw River. These steel-hulled, gaff-rigged schooners are typical of the type that sailed the Great Lakes and coastal waters right up to the end of the age of sail. Schooners were the primary means of transporting goods and people over long distances. Continue reading

Fortifying a Spare-Parts Scootboard

By Bill Bertelsen

“Daddy, can we build a scooter from these old pieces of wood?”

Thus began a father-daughter project with my 8-year-old that provided a learning opportunity for both of us. That weekend Mikayla had been scrounging in our spare lumber barrel and found two items that immediately suggested themselves as “scooter parts.” After examining her selections, I had to agree. One piece was a 32″-long strip of A/C grade Southern yellow pine plywood, about 5 8″ thick and 3½” wide. It was the perfect size for the “chassis.” The other piece was a stick of solid oak, ¾”×1¼”×33½”, ideal for anchoring a handle bar. Continue reading

The Limitations of Statues

By Bill Bertelsen

Creating lasting outdoor art has challenged humans since the dawn of time. One has only to think of the pyramids (still there), Stonehenge (mostly there), the Colossus of Rhodes (long gone), or the Easter Island monoliths (surviving, but then two heads are better than one). In more recent times, there’s Mt. Rushmore, Stone Mountain Georgia, and the Statue of Liberty. The goal is nothing less than perpetuity. But of course, outdoor sculpture needs to be done right or it won’t last. Making statues, e.g., permanent structures that look like people, is particularly difficult. Continue reading

Hydromat Panel Test, an ASTM Standard

Previous Epoxyworks have reported test results from the “Hydromat,” a unique structural test developed at Gougeon Brothers, Inc. The American Society for Testing and Materials (ASTM), after a rigorous review by its D30 Committee on Composites, approved the Hydromat test method as an official ASTM standard. Continue reading
