continued from page 21 counting money) to give them a better grip on the wood. Cutting larger circles and arcs is just a matter of cutting a big curve. Sometimes 1 use both hands to guide the work on these longer arcs, which is similar to cutting straight lines with both hands feeding. Try to keep the wood moving and turning all of the time. Remember when you are cutting curves that the blade cuts straight, so you cannot make a cut without turning the wood. If you arc feeding the wood straight at the blade, you are cutting straight lines and not arcs. Look at the blade ■HSMB'.i! ,,, I from the side and A nice sharp corner represents one of the harder cuts for some notice that it has a scrollers. To do this, we follow the line right into the corner, slight bow. The stop to allow the blade to catch up, and then turn the wood amount of bow around. depends on how ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ hard we are feed- - / _ ing the wood into the blade, Now wc are going to back the blade up a little in the cut and turn the wood around. K^gjijpi To help hold the blade in place while making the turn, you can apply a little pressure to the side and back of the blade as you turn the wood. That pressure will help keep the blade indexed in the cut; it is kind of pivoting on the corner of the blade. Use just enough pressure to keep the blade indexed, and make the turn fast, (or you will burn the wood with the back and sides of the blade). Be sure that the teeth turn in the waste side of the cut so you do not leave a mark in the design. All of these tips may seem awkward at. first, but don't give up. Once you practice and learn them, you will find scrolling projects that once looked quite difficult to be a whole lot faster and easier. This bow is one of the reasons that some people have trouble cutting. They keep feeding until the blade hits the stop line then they stop. Look where the blade goes when it catches up with the cut: way past the stopping point. Remember that, when you get to a stopping point, you need to let the blade catch up with the cut. before you gel there. It only takes a slight pause for the blade to catch up. Play with this theory on some scrap wood and you may figure out why some of your cuts always seem to be so overextended. ■!• •»«•..vaffl imir......linn il 22 • Creative!
