During week long, hands-on classes, renowned furniture maker Michael A. Doerre demonstrates the building techniques he uses to make his original design, the Number One Chair. He teaches students a system of construction and leg seat joinery based on the use of a table saw, band saw, router and simple hand tools. Continue reading

What started out to be a relatively easy job of replacing the motor mounts and cutlass bearing on my 1983 Nelson/Marek 36 turned into building a completely new rudder. Once I removed the rudder, I had planned on fairing and applying a WEST SYSTEM® epoxy barrier coat. However, upon closer inspection, I noticed that the rudder appeared to be bent. At one of our Saginaw Bay Community Sailing Continue reading

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

We have performed tens of thousands of adhesion tests over the years and many of these tests were done on metal surfaces. Below is a summary of tests done on a variety of metal surfaces and done with a variety of surface preparations. As you look at the chart, notice the surface preparation that gives the highest number.
All the tests shown below were performed using a PATTI (pneumatic adhesive tensile test instrument) meter. We chose this test method as our default adhesion Continue reading

Even though we’ve been promoting the use of WEST SYSTEM® epoxy for repairing fiberglass boats (boats made with polyester resin) in our manuals and Epoxyworks for many years, we continue to receive inquiries asking whether it is appropriate to use epoxy for polyester boat repair. Because of the misinformation still prevalent in marinas, local yacht clubs and on the Internet, we felt it was time to restate the case for epoxy. Continue reading

Most production fiberglass boats are made with polyester resin. WEST SYSTEM® epoxy is a wonderful material for repairing polyester fiberglass boats. One reason for this is the ability of epoxy to form a stronger mechanical bond to a damaged laminate than polyester resin. Epoxy also provides a better moisture barrier than polyester resin.

One of the little-known or understood characteristics of modern fiber-reinforced plastic composites is the loss of some initial stiffness capability after repeated cyclic loading. Loss of stiffness can be significant enough to cause a noticeable effect on performance, depending upon laminate makeup and degree of cyclic loading.
Loss of initial stiffness after repeated cyclic loading was first noticed in several highly competitive racing dinghy classes where older boats that had been sailed hard for Continue reading
