An apparatus for crimping a radially expandable stent includes a pressure vessel, shaping balloon, and mandrel. The mandrel is configured to slidingly receive a stent thereon, and to be slidingly advanced into the pressure vessel. The shaping balloon is inflated to radially compress the stent onto the form of the mandrel; such compression need not be uniform. Pressurization of the shaping balloon facilitates the expansion of the balloon to achieve compression of the stent, with depressurization of the shaping balloon causing the balloon to return to an unexpanded state. 1.

A machine can form a work piece into a bowl subcomponent of a steel pan musical instrument. The machine includes a pressure lid and a die mold. The die mold may be formed of non-metal layers stacked between metal layers. In example operation, a blank or work piece is inserted between the lid and die mold. The lid is pressed down (e.g., by a hydraulic ram), forcing a portion of the blank into a face groove of the die mold for sealing. Pressurized water or other fluid introduced between the lid and the blank exerts pressure on the sealed portion of the blank and stretches the blank to conform to a bowl shape of the die mold. Note regions can be introduced by this machine-performed shaping and/or by subsequent manual operations to further prepare the work piece for incorporation into a steel pan musical instrument. 1. A method of forming a steel pan musical instrument , the method including:providing a metal sheet as a work piece from which to form at least a portion of the steel pan instrument;providing a pressure lid comprising (i) a press collar, (ii) a fluid passage extending through the pressure lid, (iii) a guide shaft extending from an underside of the pressure lid, and (iv) a groove formed in the underside of the pressure lid;coupling the press collar of the pressure lid with a hydraulic press;coupling the fluid passage of the pressure lid to a source of pressurized fluid;installing a ring in the groove of the pressure lid; providing a base plate of the mold die;', 'providing at least one spacer plate of the mold die;', 'providing a cap plate of the mold die;', 'positioning the base plate, the at least one spacer plate, and the cap plate together into a stack such that the at least one spacer plate is positioned between the base plate and the cap plate; and', 'coupling the base plate, the at least one spacer plate, and the cap plate together by extending rods through the stack and securing the rods to secure the stack together;, 'providing a mold die comprising ...
