10. 1. The blade is a circular band of steel with teeth shaped on its front edge. 2. The upper blade guide is an assembly that keeps the blade from twisting. The depth of cut is adjusted by raising or lowering the upper blade guide. 3. The upper blade guide adjustment knob is used to raise and lower the upper blade guide. It is on the right side of the saw. 4. The work table is the support for the material to be cut. A miter gauge slot is formed into the table to cut angles on the saw. The work table also has a fence guide to cut straight lines. The table is also able to tilt for angle cuts. 5. The miter gauge is a guide that will adjust to cut angles and 90 degrees. 6. The fence is a guide for straight cuts and for re-sawing thickness. MAJOR PARTS OF THE BAND SAW 10 Copyright © Texas Education Agency, 2012. All rights reserved
