How to Use Your RIDGID Wood Lathe (continued)

Making Standard Cuts

The Roughing-off Cut

has been formed, step lathe up to the next

 

Reducing a square or odd-shaped work-

faster speed. Further reductions in size

 

piece down to a cylinder of approximate

can now be carried out by cutting as

 

size for finish turning is called “Roughing-

deeply as desired at any spot along the

 

off”. Faceplate turning and large diameter

work. At this stage, long cuts, from the

 

spindles should first be partly reduced by

center off either end, can also be taken.

 

sawing but small spindles are easily turned

Roughing-off generally is continued until

 

down entirely with the large (3/4-in.) gouge.

the cylinder is approximately 1/8-in larger

 

Start the first cut about 2-in. from tailstock

than the desired finish size. Roundness

 

can be tested by laying the gouge on top

 

end - then run it toward the tailstock and

 

of the work - it will not ride up and down

 

off the end of the workpiece. Next, start

 

when cylinder is perfectly round.

 

another cut 2-in. nearer the headstock -

 

 

 

 

 

and run it, also, toward tailstock, to merge

 

 

 

 

with first cut. Continue in this manner until

 

 

 

 

2- to 4-in. from the headstock end, then

 

 

 

 

reverse the direction of tool travel and

 

 

 

 

work one or two cuts in succession

 

 

 

 

toward the headstock, and off this end of

 

 

 

 

the workpiece. NOTE: Never start a cut

 

 

 

 

directly at the end -if the chisel catches

 

 

 

 

the end, it will damage the workpiece.

 

First Cuts

 

Never take long cuts while corners remain

 

 

 

 

 

 

on the work, as this tends to tear long sliv-

 

 

 

 

ers from the corners.

 

 

 

 

The first series of cuts should not be too

 

 

 

 

deep. It is better to partially reduce the

 

 

 

 

work to a cylinder all along its length; then

 

 

 

 

start a second series of cuts to complete

 

 

 

 

 

 

 

 

 

Testing Roundness

 

reducing it to a cylinder. Once a cylinder

 

 

 

 

 

 

 

 

 

 

 

Rough-cutting To Size

 

 

 

 

The roughing-off cut can be made to accurately size the cylinder to a given diameter.

Another method is to make a number of sizing cuts at intervals along the work, then use the gouge to reduce the whole cylinder down to the diameter indicated by these cuts.

Making Sizing Cuts

Sizing cuts are useful to establish approx- imate finish-size diameters at various points along a workpiece. The work can then be turned down to the diameters indicated - and be ready for finishing. Diameters for sizing cuts should be planned to be about 1/8-in. greater than the desired finish diameters.

A sizing cut is made with the parting tool. Cut “in” with the parting tool. Turn the

lathe off and allow to come to a complete stop. Check the depth of cut with a cali- per. Repeat as necessary..
