SAND BLASTING APPARATUS AND METHODS
Apparatus and methods allow difficulty accessible sites of a structure to be sand-blasted. Preferred sand-blasting systems (10) are provided which include a sand-blasting fixture (30) to support a sand- blasting nozzle (24) and a distal portion (22-1) of the supply hose (22) in such a manner that the spray of grit particulates may be directed against the difficulty accessible site of the structure. The fixture (30) most preferably includes rigid proximal and distal support tubes (32, 34) joined to one another so as to establish an angle therebetween (most preferably about 90°), and a rigid back-lash support member (38) extending outwardly from the distal support tube (34). In such a manner, the distal portion (22-1) of the supply hose (22) is movably supported within the proximal and distal support tubes (32, 34) such that the nozzle (24) positioned adjacent to the back-lash support member may be adjustable by means of the distal portion (22-1) of the supply hose (22) being further advanced into or retracted from within the proximal and distal support tubes (32, 34). A clamp member (40) is most preferably provided to positionally fix the nozzle (24) to the back-lash support member (38).
