Radius Chine Part 1

Radius Chine Part 1

Here we get to what we feared as a difficult part of the construction. In practice it turned out very easy only when we understood few basic principles.
1. Width of the plates should be around 600mm (400 to 850). If you more you get in trouble.
2. You must respect the principle that welds should not be close to each other. So transversal welds of the radius plates must be at least 150mm from the frames and from the welds on the topsides and bottom.
3. Tou must make a plan of the plates.
4. The senter of the plates should be parallel to the ghost chine. (we took a piece of wire fom bow to stern to make it visible!

Here is my plan

And also you need to do some accurate nesting. As the 2 and 1/2 6000x2000 plates will be used completely with little scrap.


The we cut the 6mm plates accordingly

And bent to the 100mm radius the plates (two of them on one bend to save on the green)

After a while we had a pile of curved plates!

From each you can obtain 2 radius plates.

We placed an L reinforcement on the topsides and bottom plating for prevention of distorsion
 later during the welding.

An here goes the first radius

Each plate needs some trimming. We tried to leave a couple of mm between each plate.

An it grew very rapidly
