Example stands for supporting a component, such as a rotor blade, are described herein. An example stand described herein includes a blade support having an opening extending from an edge of the blade support towards a center of the blade support. The opening is to receive a rotor blade of an aircraft, for example. The example stand also includes a base to support the blade support above a supporting surface. The blade support is rotatably coupled to the base about a horizontal axis perpendicular to a central axis of the blade support such that the blade support can tilt the rotor blade relative to the supporting surface.

The apparatus of claim 4, wherein a middle section of the yoke is wider than the blade support. 6. The apparatus of claim 1, wherein the blade support includes a plurality of position holes formed in and spaced radially around the edge of the blade support, and the slewing ring includes a lock hole, further including a pin to be inserted into the lock hole and one of the plurality of position holes in the edge of the blade support to lock the blade support in a desired position. 7. The apparatus of claim 1, further including a door hingeably coupled to the blade support, the door moveable between an open position, exposing the opening, and a closed position, forming a substantially continuous edge around the blade support. 8. The apparatus of claim 1, further including an actuator to rotate the blade support about the central axis. 9. An apparatus comprising: a base; anda blade support pivotably coupled to a base, the blade support including an opening to receive a rotor blade of an aircraft, the blade support pivotable between a first position in which a central axis of the blade support is horizontal and a second position in which the central axis is not horizontal, wherein the blade support is rotatably coupled to the base via a slewing ring that receives at least a portion of an edge of the blade support, the edge of the blade support slidable along the slewing ring to rotate the blade support about the central axis. 10. The apparatus of claim 9, wherein, in the first position or the second position, the blade support is rotatable about the central axis. 11. The apparatus of claim 9, wherein the blade support is pivotably coupled to the base about a horizontal tilt axis, the horizontal tilt axis perpendicular to the central axis. 12. The apparatus of claim 11, wherein the base includes a post to move the blade support along a vertical axis, the horizontal tilt axis perpendicular to the vertical axis. 13. The apparatus of claim 12, wherein the central axis is perpendicular to the vertical axis in the first position and the central axis is not perpendicular to the vertical axis in the second position. 14. The apparatus of claim 9, further including a door hingeably coupled to the blade support, the door moveable between an open position, exposing the opening, and a closed position, forming a substantially continuous edge around the blade support. 15. An apparatus comprising: a base;a blade support having an opening extending from an edge of blade support towards a center of the blade support, the opening to receive an object to be supported by the blade support;means for rotatably coupling the blade support to the base about a horizontal axis perpendicular to a central axis of the blade support, the means for rotatably coupling including means for rotating the blade support 360° about the central axis; andmeans for locking the object in the opening. 16. The apparatus of claim 15, further including means for moving the blade support along a vertical axis.
