At the end of the season this year while riding in a local terrain park, I misjudged the approach to a pipe and ended up crashing the nose of my snowboard into the end of the pipe. Fortunately, I was able to ride away from the impact. Later in the day, I noticed that the nose of the board had been deformed. When I got home, I studied the damaged area closely and determined that it was not safe to ride the board in that condition. The entire nose area had become soft and flexible because much of the wood core in that area had been broken. In addition to the bent nose edge, the top sheet had cracked. Left as is, this would have allowed water to penetrate to the core of the board which would have made it unrepairable. The technicians at my local board shop told me it could be repaired but cautioned that I needed to use an epoxy that remains flexible after it cures to prevent the repair from breaking.

Last Father’s Day I received a new light and sleek bicycle from my family. It is by far the nicest bike I’ve ever owned. I enjoy riding it to work in the spring, summer and fall. Because it is so nice, I decided I didn’t want to bolt on the aluminum bracket used previously over the back wheel on my old bike. The bracket had served multiple purposes. It supported my travel bag and it acted as a fender to keep road water off my back while riding. I decided I would ride with a backpack instead to reduce bulkiness and thought it would be nice to make a lightweight fender that I could snap on for those rainy days. That would allow me to remove it for longer trips and on nice weather days. Continue reading →
G/flex epoxies weren’t developed with coating in mind, but early on in its applications testing we discovered it was excellent at dealing with impact. This became evident when we used G/flex 650 (the unthickened version) as a coating and when we used G/flex 655 (the thickened version) as a protective buildup.
G/flex 650 is not optimized for use as a coating, but we found it was worth the extra effort it takes to apply to wooden parts that might get dented in service, such as wooden canoe paddles and boat oars. As a coating, G/flex deflects without cracking when the wood beneath it gets dented. Continue reading →
The evening of March 19, 2013 I inspected my 217cm Atomic™ downhill race skis in preparation for race day. Because of the early ending to winter in 2012, these skis have not seen the light of day in almost two years. The only real chance I get to ski with them is at the annual Boyne Highlands Downhill Race in Harbor Springs, Michigan. This late March tradition is usually the grand finale of Michigan’s ski racing season. This year the weather was shaping up perfectly for outstanding conditions, and I was chomping at the bit to ski fast! Much to my surprise, when I picked up one ski I found that a section near the tail was delaminating. On the inside edge of the left Continue reading →
Meade Gougeon was intrigued by the Renovo Bikes company of Portland, Oregon after spotting their wares on display at the Wooden Boat Festival in Port Townsend, Washington last fall. Meade has long been a serious cyclist and understands better than most the value of wood as an engineering material. He saw in Renovo an opportunity to combine two of his great loves, wood and bicycles. Continue reading →
I will start by saying that, in my opinion, most carbon fiber bicycle frames that have sustained damage from an impact should not be repaired—there are too many damaged fibers that are typically unseen. The two repaired frames featured in this article had damage caused by operator error, not impact. The last two frames are prime examples of parts that should not be repaired for safety reasons.

Fly fishing, particularly for Atlantic Salmon, has been my lifelong hobby. The fly rod itself has an ancient past but its technical prowess as an instrument to launch line and fly to a designated spot on the river was epitomized by the arrival of handcrafted split bamboo rods in the late nineteenth century.

Todd Lynch, one of our valued employees, brought in a damaged plastic panel from the back end of an 11-year-old pop-up camper and asked if it was worth fixing. It came from his hunting camper which had been rear-ended. He just wanted it to be functional. The impact had made cracks at nearly every screw hole for holding the panel in place, making it doubtful it would last another trip down the highway. Continue reading →
Jim Costello of Dallas, Texas, recently asked the Tech Staff about mounting a transducer to the hull of his 1983 Bayliner Capri Classic.
“The user manual for my new Hummingbird fish finder says that the transducer can be installed in the hull with a slow curing epoxy. It says to try to eliminate all bubbles. I have105, 206, 404, and 406 on hand. What if I just mix up some peanut butter thick paste and use that? Or do you have any other suggestions? I can mount the transducer on a part of the hull that is thin enough for the application, according to Hummingbird. Thanks.” Continue reading →
