14Mounting the WorkMove the tailstock to approximately 1 to 1-1/2"from the end of the work piece and lock inposition. Turn the tailstock handwheel until thecenter makes contact with the work piece.Continue to turn the hand wheel and slowlyrotate the work piece by hand. After the workpiece becomes difficult to turn by hand, reversethe hand wheel approximately one quarter turnand lock the tailstock spindle (Figure 10).Adjusting the Tool RestPosition the tool rest approximately 1/8" awayfrom the work piece and 1/8" above the workcenterline. After some experience has beengained, this position can be varied slightly to suitthe operation.Position of HandsThere is no "proper" position for the hands whenusing chisels. Most beginners begin by using thepalm-down grip (Figure 11) for better control andswitch later to the palm-up position (Figure 12)for better manipulation. In the palm-downposition, the little finger or heel of the hand actsas a guide along the tool rest. The first fingeracts as a guide when using the palm-up method.Roughing a CylinderUse a large gouge and run the lathe at a slowspeed to rough-off the sharp corners of thework. Begin the cut 2 to 3 inches from thetailstock and work toward and off the tailstockend. Continue by cutting the next 2 to 3 inchesleft of the first cut, preferably working toward thetailstock end. This method of always workingtoward the tailstock is preferred because itthrows the chips clear of the operator. Do notrough cut by taking one long pass at the workpiece and do not start cuts at either end of thework piece. This has a tendency to tear longslivers from the work piece. Roll the gouge overslightly in the direction of the cut for best results.Once a cylindrical form has started to takeshape, step up the speed one or two stops.Smoothing a CylinderUse a large skew chisel with the cutting pointnear the center of the chisel and high up on thework piece. Support the chisel on the tool rest atall times. To locate the proper cutting position,place the chisel flat against the work piece withthe skew well over the area to be cut. Pull backslowly on the chisel until it bites into the wood.Raising the handle will increase the depth of cut;lowering the handle will decrease the depth ofcut.Figure 10Figure 11Figure 12
