Industry:Aviation
A cutter used to shape blocks of Styrofoam. The wire is stretched tight between the arms of a frame and heated by electrical current. The hot wire melts its way through the foam.
Industry:Aviation
A cutting tool used for machining hard metal. The cutting edge of the tool is an industrial diamond.
Industry:Aviation
A cutting tool used to cut the chamfered holes into which flush rivet heads fit. The cutter, which is driven by a shaft mounted in a hand-held drill motor, fits through a bushing in the body of the stop unit and extends out beyond a fiber collar on the end of the body.
The body is made in two parts threaded together to allow the length of the body to be adjusted. The body length determines the amount the cutter protrudes, and this, in turn, controls the depth of the hole made by the cutter. A fiber collar prevents the stop scratching the soft metal being countersunk.
Industry:Aviation
A cutting tool used to produce a smooth surface on the inside of a drilled hole. A reamer has several sharp cutting edges that cut away the rough surface left by the drill.
Industry:Aviation

Industry:Aviation
A cylinder and piston arrangement used to convert hydraulic or pneumatic fluid pressure into work. Fluid under pressure moves the piston that does the work.
Industry:Aviation
A cylinder of a reciprocating engine ground in such a way that its diameter at the top of the barrel is slightly smaller than the diameter in the center of the barrel.
The large mass of metal in the cylinder head absorbs enough heat to cause the top end of the barrel to expand enough more than the remainder of the barrel that, at the normal operating temperature, the diameter of choke-ground cylinders becomes uniform throughout.
