RIDGID WL1200LS1 manual Smoothing a Cylinder, Cutting a Shoulder

Smoothing A Cylinder

The final 1/8-in. can be removed in two ways. Either use the 1 -in. skew, working from center toward both ends and taking lighter and lighter cuts until finished.

Cutting A Shoulder

A shoulder can be the side of a square portion left in the workpiece, the side of a turned section, or the end of the work- piece. Most shoulders are perpendicular to work axis; but a shoulder can be at any angle desired.

First, mark position of the shoulder with a pencil held to the revolving workpiece. Then make a sizing cut with the parting tool, placing this cut about 1/16-in. outside the shoulder position, and cutting to within about l/8-in. of the depth desired for the area outside of the shoulder. If shoulder is shallow, the toe of the skew can be used to make the sizing cut; but do not go in deeper than l/8-in. with the skew unless wider and wider vees are cut to provide clearance for this tool.

Use the gouge to remove any waste stock outside of shoulder-and smooth this sec- tion, up to within l/8-in.of the shoulder, in usual manner. Finishing of the shoulder, unless it is more than 1 -in. high, is best done with the 1/2-in. skew. First, toe of skew is used to remove thin shavings from the side of the shoulder - down to fin- ish size. Hold skew so that bottom edge of bevel next to shoulder will be very nearly parallel to side of shoulder, but with cut- ting edge turned away at the top so that only the extreme toe will do the cutting. If cutting edge is flat against shoulder, the chisel will run. Start with handle low, and raise handle to advance toe into the work. Cut down to finished diameter of outside

area; then clean out the corner by advancing heel of the skew into it along the surface of the outside area. Tilt the cutting edge, with handle raised up, so that only the extreme heel does this cut- ting.

If shoulder is at end of work, the process is called squaring the end. In this case, reduce outer portion to a diameter about 1/4-in. larger than tool center diameter, then later saw off the waste stock.
