A roll body for a hydrostatic rolling tool includes a center, an axis of rotation running through the center, and a machining zone for rolling a workpiece. The roll body is rotatable about the axis of rotation and the machining zone has a working profile line formed in a cross-section of the roll body. The working profile line has a first working arc extending around a first machining center and a second working arc extending around a second machining center. The first machining center is arranged offset to the center, and the second machining center is arranged offset to the center and offset to the first machining center. In an example embodiment, the roll body has a parallel to the axis of rotation, the first machining center lies in the cross-section on the parallel, and the second machining center lies in the cross-section on the parallel.

An arm removal system for removing an arm. The system includes an anvil, and a removal assembly with at least two jackscrews. The arm has an extension radially extending from the arm and an arm outer surface. The arm is disposed within a wedge shaped collet that is disposed within a socket in an aircraft with an aircraft outer surface. The removal assembly includes an extension engaging surface and threaded jackscrew holes for accepting the jackscrews, such that when the jackscrews are tightened within the jackscrew holes, the jackscrews apply force on the anvil and the aircraft outer surface in the direction away from the removal assembly such that the arm is eventually removed entirely from the aircraft.

In order to improve and facilitate shimming between two parts, a deformable shim is provided that comprises a main structure of an at least partly cellular region. The main structure is compressible by plastic deformation from an initial volume to a deformed volume, wherein the deformed volume is smaller than the initial volume. In a deformed state, the main structure maintains the deformed volume without further or continuing compression force. Further, the main structure is arrangeable between a first aircraft component and a second aircraft component to create a predefined distance between the first and the second aircraft component.

A method of manufacturing a coil includes forming a wound body by winding a coil wire in multiple layers, and forming a coil by pressing the wound body using a die surrounding the wound body and compressively deforming the wound body. The wound body has a contour of a rectangular or substantially rectangular shape in cross section, and includes coil wire portions located in the cross section of the coil wire, the coil wire portions being aligned along each side of the rectangular or substantially rectangular shape. The coil has a contour of a fan shape or approximate fan shape in the cross section, where the coil wire portions are aligned in a direction along an arc and a radial direction of the fan shape or approximate fan shape.

An assembly apparatus is for assembling a first member and a second member. The assembly apparatus includes a first gripping section, a second gripping section, and a driving section. The first gripping section includes a contact member and an elastic member. The second gripping section includes a contact member and an elastic member. The driving section drives the first and second gripping sections. The driving section drives the first and second gripping sections such that the contact member of the first gripping section and the contact member of the second gripping section make contact with the second member. The first and second gripping sections grip the second member through the two elastic members urging the respective contact members. The driving section drives the first and second gripping sections such that the first member and the second member are assembled.
