A method of assembling a first part and a second part. The method includes the step of integrally forming an attachment device and a first part. For example, the attachment device may be a nut plate operative to retain a nut therein, and the first part may be an air duct. The nut plate and the air duct may be integrally formed via selective laser sintering or stereo lithography such that the nut plate is an integral feature of the air duct. A nut may be retained in the nut plate, and a mating bolt may engage the nut to attach the air duct (i.e., the first part) to the second part.

A blast head for abrasive blasting has a nozzle for directing a blast media at a surface being treated and a housing for containing the blast media after it passes through the nozzle and for facilitating recirculation of the blast media. An adjustment mechanism facilitates varying of the orientation of the nozzle with respect to the surface being treated, so as to facilitate enhanced blasting thereof.
