Lightweight Laminated Spoon Blade Sculling Oars

In English
Wer gerne den dafür erforderlichen Aufwand treiben möchte, ist herzlich dazu eingeladen, die knapp 80 Seiten umfassende Beschreibung ins Deutsche zu übersetzen :-)).

Rick Thompson from the USA created these lightweight laminated spoon blade oars. They are 2.9 meters long. The weight is 1.62 kgs each. With his kind allowance I offer here for free a description of the development and the making of these oars, an 1:1 drawing of the blade templates, and a drawing of the loom as well.

Rick is using ergonomic mountain bike handlebar handles for his oars (see instruction document). With this he’s able to use a round loom sheated with a rope together with oval bronze oarlocks instead of the usually used plastic oarlocks for D-shape looms. This is useful for a way less noisy row ( no click-clack when feathering/squaring the blades at all).

The drawing can be printed on two A3 Portrait sheets. The blue lines of the grid have a distance of 50 mm. They are thought to help you to put the two sheets precisely together.

Loom with conventional round grip (click to enlarge)

Loom with Grip

The loom

The loom shown here including the grip (length 160 mm) has a length of 2680 mm. This results in an oar with a total length (grip, loom and blade) of 2910 mm. The diameter in the oarlock area of the loom is made to be able to mount a D-shape oarlock sleeve.
All measures can be changed according to your specific needs.

The loom without the grip has a length of 2520 mm. The diameter at the grip end is 38 mm, the diameter of the oarlock area (relative to the grip end of the loom positions 620 – 1120mm) 44.5 mm, and the oval form at the blade end of the loom (relative to the grip end of the loom positions 2230 – 2520 mm) is 22 x30 mm. The conventional grip length is 160 mm, and its diameter is 32 mm.
The grip handle is a round piece of wood. It is inserted and glued into a hole drilled into the loom’s grip end.

The grip can be made as an integral part of the loom too.
