Cutting Compound Miters on Picture Frames and Boxes A compound miter is a cut requiring both a miter setting and bevel setting A com pound miter is used for making frames or boxes that have sloping sides and are wide at one end and narrow at the oppo site end Compound miters are tricky to make because the miter setting and bevel setting are directly related to each other Every time the miter setting is changed the bevel setting must also be adjusted likewise every adjustment to bevel requires a corresponding adjustment to miter Because it may take several tries to obtain the desired angle it is advisable to make test cuts on a scrap piece of mate rial Cutting Bowed Material Before cutting a workpiece check to make sure it is not bowed If it is bowed the workpiece must be positioned and cut as illustrated Do not position workpiece incorrectly or try to cut the workpiece with Hold workpiece tight against fence so there is no gap Correct 30 out the support of the fence This will cause pinching of the workpiece on the blade The workpiece could suddenly jump or move and your hand could hit the blade Incorrect Workpiece Clamp Usage WARNING Avoid thrown workpieces Avoid binding the work against the blade Always hold or clamp your work down to the saw Do not hold or clamp the work piece on both sides of the blade The blade can throw a cut off piece if you confine t
