MAKING EDGE-TO-EDGE See Figures 9 - 10. JOINTS Edge-to-edge joinery is one of the most basic and easilyconstructed joints. • Unplug the biscuit joiner. • Prepare the workpieces by laying them side by side on a workbench in the order in which they will be assembled. • Using a square, determine the location of each biscuit spline joint and mark the center of each joint by drawing a line across each workpiece. NOTE: Mark the edges 2 in. from the ends of the workpieces. The joint will be stronger if you use multiple biscuits placed close together. • Loosen the locking knob approximately one turn and set the fence angle at 90 °. • Set the fence height at the desired dimension on the scale by rotating the height adjustment knob. NOTE: The scale indicates the height of the fence from the center of the blade. • Tighten the locking knob securely. • Select the correct depth of cut setting to match the biscuit size you are planning to use. Make a test cut in a scrap piece of wood from the same workpiece if possible. • Clamp the workpiece securely so that it will not move during the cut. • Plug the biscuit joiner into the power supply and prepare to make the first cut. Grasp and hold the biscuit joiner securely with both hands. • Place the fence against the board and align the indicator marks on the fence with the centerline mark(s) on the board. • 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 all desired biscuit slots. • Once all biscuit slots have been cut, place a biscuit in each joint and dry-assemble the workpiece. Make sure each joint lines up and fits. • 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 workpieces together until the glue sets up.
