Refinishing a Wood Strip Canoe

By Tom Pawlak

About 30 years ago, I built an 18′ wood strip canoe. At the time, my family was young and I could only work on it intermittently. Over the course of six months, I had faired my mold frames, applied the redwood strips, faired the outside of the hull with a keen eye and applied the fiberglass cloth. Two months later I decided to take it off the mold to fair and fiberglass the inside. To my horror, the exterior hull bottom had a big dimple in the middle when removed from the forms. I immediately knew the cause. The humidity in my garage had skyrocketed since the outside of the hull was finished with fiberglass and epoxy. The unsealed inside of the hull had probably gained 4-5% in moisture content since the outside was fiberglassed. Continue reading

Types of Strip Plank Material

By Brian Knight

Modern strip composite construction uses narrow strips of wood or foam to make a low density core material. These strips are easy for one person to handle and are readily assembled into complex shapes. However, this assembled structure does not have much strength until it is covered inside and out with a high density fiber reinforced skin—usually fiberglass cloth. The process of making and fitting the narrow strips together is more time consuming than bending a sheet of plywood, but the technique allows for more creativity in the design. Continue reading

Rectangular or square edge strips tend to get out of alignment between mold stations, especially where the bend is tight and the planks have to be forced into position. You can build intermediate mold stations in these areas to support the planks in more places. Continue reading
