MITER JOINTS See Figures 18 - 21. There are two types of miter joints that can be made using biscuits: flat miters and edge miters. Fiat miters are used when making picture frames. Edge miters are used when making boxes or things where you don't want to show the end grain of the wood. MAKING FLAT MITER JOINTS See Figure 18. • Unplug the biscuit joiner. • Place the pieces of wood to be joined on a level workbench. • Finally, disassemble the workpieces and place a bead of glue in each slot. Also, spread a bead of glue over the entire surface of the joint. Reinsert the biscuits and assemble the workpieces. • Clamp the workpieces together until the glue sets up. MAKING EDGE MITER JOINTS See Figures 19 - 21. • Unplug the biscuit joiner. • Place the pieces of wood to be joined on a level workbench. • Mark the centerline of the joint on each board. •edcogomensing, Using a square, draw a through the center of each joint perpendicular to the mitered Z,z/_i"i_, MARK(S) BISCUIT Fig. 18 • Set the fence angle at 90 °, set the fence height at the desired dimension on the scale, select the correct depth of cut setting for the biscuit size you plan to use, and clamp the workpiece securely. • Align the indicator mark on the fence with the centerline on the workpiece. • Plug the biscuit joiner into the power supply and prepare to cut the slot. • Depress the switch trigger to turn on the biscuit joiner, then push it forward to extend the blade into the wood. • When the base assembly bottoms out against the depth of cut adjustment knob setting, pull back, releasing pressure on the spring. The blade will retract from the biscuit slot. • Repeat this procedure for cutting the mating slot and all required miter joint slots. • Once all slots have been cut, place a biscuit in each joint and dry assemble the workpieces. Make sure each joint lines up and fits. CENTERLINE MARK(S) Fig. 19 • When making edge miter joints with workpieces that have different thicknesses, clamp the pieces securely to a workbench with the long sides up. This will assure that the outside surfaces will match. • Loosen the locking adjusting knob and set the fence angle at 135 °. • Set the fence height at the desired dimension on the scale by rotating the height adjustment knob. • Tighten the locking knob securely. 18
