A question frequently posed to our technical staff is “can I thin WEST SYSTEM® epoxy so it will flow or penetrate better?” The answer to that question is “yes, but not without consequences.” Many of the advantages of thinning epoxy are offset by disadvantages in other areas of epoxy performance.
We like to think that all our customers are considerably above average, but every once in a while we encounter someone really exceptional. On January 25, 1999, our tech service department took a phone call from Elizabeth Tedford, a 7th-grader from Lansing, North Carolina. She was working on a science fair project that involved testing the adhesive strength of epoxy. Continue reading →
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 →
My porch railing at home was badly in need of painting even though I had painted it the summer before. After just one Michigan winter, the paint had cracked and lifted. I wondered to myself if coating the top rail with WEST SYSTEM® epoxy would improve this poor situation and decided to turn the top rail into a small R & D project. Continue reading →
From ice boats to racing multihulls, wind turbine blades, and a thousand other projects — ours and customers — working with epoxies and our customers since 1969 has been interesting. The decades of experience in the shops, labs and libraries have given us a pretty good feeling for epoxy technology. We know its strengths and weaknesses, and most importantly we understand and appreciate its versatility.
To a fanfare of music, lights and fireworks HRH Prince Andrew pressed the button and the 400 invited guests watched anxiously as the largest wooden ship under construction in the world began to move. Continue reading →
Keeping your boat dry for livability and longevity
By Joe Parker
You decide to head down to your boat to take advantage of a beautiful Saturday afternoon in late August. You haven’t had a chance to use your boat in about three or four weeks, and you are really looking forward to catching up with your friends at the harbor. Continue reading →
Epoxyworks reader Jim Cronan of St. Ignace, Michigan completed a Phil Bolger designed Martha Jane that he had worked on for five years. He offed a couple of suggestion the helped him with his project. Continue reading →
Cover Photo: “The last thing I needed to worry about was whether or not my boat would stay intact.
Tiptoeing on the edge of danger, I was crouched down on my knees in the cockpit of my ten-and-a-half foot “sheet of plywood” hydroplane, screaming across the water at speeds reaching 65 mph. Crossing the start line with wide open throttle, I, along with eleven other boats, aimed for the first turn pin. Who will make it there first? With just inches between boats, whitewater from the roostertails engulfed my boat and hammered against my helmet’s visor. These roostertails, which extended thirty feet behind the engine and turn fin, were difficult, almost impossible, to avoid. During this moment of frenzy, I prayed that another hydroplane had not stalled in front of me, or worse . . . flipped.Continue reading →
When I was a kid, my older brother had a slingshot that was fashioned from a tree crotch. The wood fibers neatly followed the desired shape and nicely addressed the forces when operated. Centuries ago, many large ship components — knees, hooks, and floors were selected from forks, crotches and crooks of trees for much the same reasons. One-piece wooden parts were very reliable and the naturally grown beams and frames were key components of ship construction. As the availability of large naturally shaped timber diminished, large curved components were made of stacked and mechanically fastened smaller pieces of wood. Laminated wood structures weren’t possible until the relatively recent development of strong adhesives. Continue reading →
