Cap Ornament
I call them cap ornaments because they have a cap on top of a sphere. Not a round cap like on a acorn, but a square cap. Turning from square stock with the aid of temporary joints gives the cap dramatic scallops.
The cap is hollowed using a template:
Hollowing Template for 2.9" sphere
Hollowing Template for 3" sphere
The cap can be turned using the shadow sphere jig using a pattern.
The cap can also be turned using a template:
You can turn a sphere for the cap using the shadow sphere jig or with a Template
After hollowing the top of the cap is turned using a cap drive:
Cap Drive for supporting the hollowed cap while turning the top.
Here are some samples showing the diversity of looks available by substituting various spheres the cap sits on:
