GDP-3 Rosette

The GDP-3 rosette is commonly known as the "triple finial" rosette, and named in honor of Gorst duPlessis.

This rosette is commonly used at very small radii where the design of the rosette collapses into itself. At a small enough radius, the three patters will be separated. This can then be fluted along a column, creating a triple finial.

Phasing Holes 1/8 & 1/30 lobe There are two sets of phasing holes in this rosette.
Works For End Cutting Near side cutting
Far side cutting, or using rear rubber column
Side Cutting Near side cutting
Far side cutting, or using rear rubber column
Complementary Rosettes

This rosette is typically used for making finials. However if you want to use this rosette for other work, consider pairing it with one of these.

Examples
No pictures at this time, however the video below shows some nice examples.


Other Notes

At the 2018 Ornamental Turners International Symposium, Eddie Bell gave a presentation about how variations in the shape of the rubber can change the shape of the Gorst du Plessis finials. This is a nice presentation about the effect rubbers can have on the object shape.
