Method of rotating mold or other articles

A method for rotating an article comprising:

• placing the article in an L-shaped mold rotator having a first section and a second section approximately perpendicular to the first section;
• rotating the L-shaped mold rotator, along a curved section that joins the first section and the second section of the L-shaped mold rotator, from a first position to a second position;
• and
• changing a center of gravity of the L-shaped mold rotator by transferring a material, within at least a conduit and during the rotating, between a first internal section of the L-shaped mold rotator and a second internal section of the L-shaped mold rotator, wherein a resulting changed center of gravity stabilizes the L-shaped mold rotator in the second position.

A method for rotating an article comprising:

• placing the article in a rotator, wherein
• the rotator comprises a first section comprising a first flat face and a second section comprising a second flat face,
• the first section and the second section are positioned substantially perpendicularly to each other to produce a base and an L-shaped platform configured to receive the article,
• the base includes the first flat face, the second flat face, and a curved section, wherein the first flat face and the second flat face are perpendicular to each other, and wherein the curved section is at the intersection of the first section and the second section and joins the first flat face to the second flat face and exhibits a concave towards the L-shaped platform, and
• the rotator comprises a stabilizing system including at least a conduit configured to move a material between the first section and the second section, and the stabilizing system is configured to stabilize the rotator in a first position wherein the rotator is supported on the first flat face and in a second position wherein the rotator is supported on the second flat face by transferring the material within the rotator between the first and second sections;
• and
• rotating the rotator and the placed article along the curved section from the first position to the second position, wherein a center of gravity of the rotator changes during the rotation as a result of transferring the material between the first and second sections and stabilizes the rotator in the second position.
