Item details

RARELY SEEN ✔ clamping tool traditionally used for Norwegian lapstrake boat construction. After building a number of traditionally constructed lapstrake boats—I made a dozen of these clamps to facilitate positioning and fastening the overlapped planks (or strakes) on a series of classic boat models. I was intrigued with the extraordinarily simple design of the Norwegian style clamp and much enjoyed building this clever tool to support my TRADITIONAL boat construction projects.

DESIGN ➤ which incorporates a cam driven clamping design is simple and cleverly implemented. As far as I am concerned—this is a pinnacle example of functional tool design.

MATERIALS ➤ The clamp is made from Maine Rock Maple (as tapped for maple sugar) and northern New England CHERRY for the handle and a bit of metal strapping and riveted bronze rod to assemble and articulate the pieces.

USE ➤ This clamp is designed to hold overlapping boat planks in alignment prior to clinch nailing or riveting them in place. This design is clever because it allows the plank position to slip laterally and assume a fair curve. Though a traditional boat builder will readily understand the application of this tool—others may be mystified by my description—which is a bit difficult to follow if one has never built traditional water craft.

★★ Though I see no traditional boat builders listing on Etsy—this tool does have many advantages over the traditional wedge driven jewelers clamp. The extensive Etsy jewelry contingent would derive considerable benefit by considering this exceptional tool.

CLAMPING CAPACITY ➤ The clamp jaw width is 1.25 inches and the maximum jaw depth is 6 inches. Inspecting the close image will revel 2 holes for the side strap position. The thickness capacity of the clamping jaws can be fine tuned by adjusting to the alternate clamping strap pivot hole. By moving the pivot point screw to the alternate position the clamping range may be moved from 1.5 > 1.875 inch. Drilling additional pivot holes would expand this fine tuned adjustment.

VALUE ➤ My work is not inexpensive because I have no economies of scale. Compared to industrial manufacturing handcraft is laughably inefficient. Perhaps it's foolish to make something one step at time or perhaps that's the only way to create unique qualities?

HAND ➤ The clamp listed is entirely my own hand work—from adapting the traditional design to fabricating the wood and metal parts. I did everything involved but process the raw materials. Though I made this clamp many years ago it is in as-new condition. This clamp I used in the construction of a dozen traditional water craft and with care will be functional for many generations.


SHIP ➤ The photographed piece is an example of the one I will pack and ship to you. My work is only shipped safely via UPS. The $28.50 cost of shipping is added to the price of the clamp for US delivery..
