Light as a Feather

How I made a composite fender for my bike

By Tom Pawlak — GBI Technical Advisor

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 composite 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

When the Cat’s Away

Repairing a cracked wall plaque with G/5 Adhesive

By Julie Jezowski

Like a lot of people, when I’m at work I like to keep busy. It makes me feel good about myself and the bonus is that the day just flies on by. Having said that, it’s also nice to escape from the walls of my office now and then and head out into the shop to see what the guys are working on. For some reason, this gravitational pull I feel from the shop occurs more when my boss is away. We can just call it an unexplained phenomenon and leave it at that. During some of my excursions to the shop rather than just observing they let me help them with the projects they’re working on, which I absolutely love! Continue reading

Jan C. Gougeon's final project, STRINGS.

Strings Centerboard Adjustment

By Greg Bull — GBI Technical Advisor

Strings, as unique as the man who designed it, continues to be a work in progress for us at GBI. In Jan Gougeon’s first year of sailing Strings, he noticed the boat felt sticky at times. He thought it might be the centerboards jibing too much and the solution might be an adjustment to lock them straight. The centerboards work as jibing boards by having two high spots on each side of a centerboard head creating the pivot point to get the boards to change angle, or jibe. The actual pressure from the boat going through the water and wanting to slide sideways gets the centerboards to jibe. Continue reading

Student-designed high-mileage prototype vehicles

By The Students of Goshen High School’s Engineering Design & Development Class

We are a group of students from Goshen High School in northern Indiana and for the past six years we’ve had the opportunity to design, build and test high-mileage prototype vehicles in a class called Engineering Design and Development. Year to year, this program serves about 30 students aged 15 to 18. We begin with little to no background in an automotive or engineering technology background, and through the course of this program learn many new skills. Continue reading

Fairing the Bottom of Adagio

By Greg Bull — GBI Technical Advisor

While fairing the bottom of your boat may seem beyond your reach, it is a project that novices and experienced boaters alike can accomplish with a few simple tools and a love of a little manual labor. Most seasoned sailors would agree that a clean bottom leads to faster sailing. Sometimes it may be necessary to do more than scrub away the algae and zebra mussels, though. In the case of Adagio, 44 years of sailing was starting to ripple the bottom of the boat. Simply put, it was time to fair the bottom.  Continue reading

Repairing an Edison Concert Phonograph

By Tom Pawlak — GBI Technical Advisor

Ronnie Janowicz, a good friend of mine, called to say the wooden horn on his antique Edison Concert phonograph was cracked. I had Ronnie bring it by so I could take a look.

I told him it could be repaired very nicely with epoxy if that is what he wanted to do. “Why wouldn’t I want it repaired that way?” he asked. I explained that repairing an antique with epoxy may affect its resale value if the potential purchaser objects to the repair. Some collectors take a dim view of wooden antiques being repaired with epoxy because repairs are not easily reversible like they would be if hide glue was used for repair instead.

Wooden Goblet Rx

By Tom Pawlak — Retired GBI Technical Advisor

Vern, a good friend of mine, turned the exterior of a wooden goblet made from a nice piece of spalted sycamore. Unfortunately, the blank was not as dry as he thought and it cracked along one edge as it sat uncovered on his lathe overnight. He called to see if there was anything available for gluing it back together. I said I had some ideas and asked him to drop it off at work so I could take a stab at the repair. Continue reading
