Installing Glass. - OD16530069

over the shop area, it is suggested that a rubber inner tube be tacked

around the inside of the roughing box (about onehalf inch above the

roughing wheel). This allows free passage of glass beyond edges of the

roughing box for working edges of bevels without interference.

(2) If glass is to be rough ground oily, seam or chamfer both sharp

edges first; then run glass across the wheel from left to right, holding the

glass perfectly vertical if a flat edge is desired. Do not seam or chamfer

the edge first, but simply roll the glass back and forth as it is being

drawn from left to right, from an angle of about 45 degrees away from you to

straight up. Do not roll the glass all the way toward the operator as this

will chip the glass edge. When rounded on one side, turn the glass around

and repeat the operation. Use the full face of the wheel to prevent

grinding grooves in the face. When grooves form in the wheel, the wheel

should be replaced.

Installing Glass.

(1) Glass, in terms of its installation, is either stationary (the

windshield, some quarter windows, and the rear window) or it is moveable

(door window, tailgate window and some quarter windows). In addition to the

customary care one must take when handling glass, to protect it from impact,

there are several general precautions which should be observed whenever a

replacement is to be made.

(a) Check Parts. Be certain that the replacement part is the correct

part. The size and contour of the glass must be an exact fit in the opening

into which it is to be installed. Thus, it pays to take the time to verify

the piece before starting the job.

(b) Use Protective Covers. Over all adjacent body surfaces, to

minimize cleanup and avoid damage to paint finishes and fabrics, use a

cover. These covers may also serve as a protection against chipping the

glass or otherwise damaging the edges.

(c) Inspect Hardware. Inspect for bends or obstructions in the pinch

weld flanges, glass run channels, frames, regulators, or whatever components

may be involved in holding or moving the
