The short history of the birth of the Ve-scull - Building the Ve-scull

No two Ve-sculls are alike, this is a similar situation to the traditional Japanese sculling oar. Remember the basics of the Ve-scull are the same as the traditional oar. You decide the size of the oar, it is specific to the boat which it will be used on.

The following criteria are used to calculate the size:

* Transom of boat, height from top to water level

* When rowing the height of handgrip, whether you row seated or standing

* Distance from handgrip to oarlock

* Seated height (sitting down, when you row)

And so on... [Translators note: basic dimensions for traditional oar on history page]

Follows an example illustrated by my number 11 prototype oar. When you have made an oar please share pictures and impressions with us all.

The blade: first the material is laminated. Here the material is 15 millimeter thick Japanese cypress board, the width of blade is 90 millimeters. Thickness at the top of blade is 45 millimeters, or 3 times plank thickness. It is laminated with epoxy adhesive.

When the epoxy is cured you remove the clamps and start preparing for planing. Here the small lumber glued onto the blade can be seen at the top of the picture.

Quickly planed down to shape. When these shavings are added to hot water you have a traditional Japanese cypress bath! Here we see one of the major differences with the traditional oar, which is symmetrical in shape without distinction between the front and back of the blade. In this picture we see the left side, the front edge is slightly rounded, the rear finished much thinner.[Translators note: Think NACA profile]

Forming the arm from harder wood. In the arm the stick is installed securely. Different from the traditional oar, this stick comes out the bottom of the arm.

Connecting the blade and the arm with angle of approximately 10 degrees, you are finished!

As for the method of connecting... please refer to this picture. It shows oars 9, 10 and 11 starting from the left. On the right of the photo the long oar is the number 4 prototype which shows the evolution so far. The tape mesure is extended to 2 meters.

In the photo you can see the stick above the arm, but after the experiment, it was moved underneath (we are still using trial and error). The arm is attached with metallic screws on these trial oars. A universal joint may improve efficiency, wait and see... Because these metallic screws are easy to remove and replace the adjustment of length and angle is easier.
