This is the same as Lesson 6, except that the curve is in the opposite direction. The same diffi-

culties are met as in Lesson 5. Great care should be taken in this exercise to make the curve a correct quarter circle.

Fig. 81. Marking Spaces with Skew Chisel.

You should now be able to use the skew chisel with sufficient accuracy to mark the spaces, as shown in Fig. 31.

In using the point of the skew chisel in this manner, make but a very light mark. If you wish the point to cut deeper, go over the lines again after the rule has been removed.

A very deep cut cannot be made except by cutting out a bit of the material, for if the point of the chisel is held long in one place or pressed hard into the wood, the friction caused will heat the point and color it and may injure it very much. The tools should not be held so hard or so long against the wood as to color them even at the extreme thin edges or points.

Try to make the curves so even that there will be no mark showing where the skew chisel began to cut. Also be careful not to rub the skew chisel on the piece so hard that the grain of the wood will be bruised or crushed. Keep in mind that in proper turning the tools must cut evenly and smoothly, and that the surface must be glossy. When you have acquired the correct way of handling your tools, you will soon be able to work with considerable speed.

In case the curves are not of correct form, cut them down a little with the roughing gouge. Smooth these places with the skew chisel, then try again to work the curves.

Be careful to keep the spaces equal. After cutting the curves part way down, test the spaces with the rule and pencil, as shown in Fig. 19.
