OPERATION
MITER JOINTS
See Figures 18 - 21.
There are two types of miter joints that can be made using biscuits: flat miters and edge miters. Flat 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.
nUnplug the biscuit joiner.
nPlace the pieces of wood to be joined on a level work- bench.
nUsing a combination square, draw a line through the cen- ter of each joint perpendicular to the mitered edges.
nSet 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.
nAlign the indicator mark on the fence with the centerline on the workpiece.
nPlug the biscuit joiner into the power supply and prepare to cut the slot.
nDepress the switch trigger to turn on the biscuit joiner, then push it forward to extend the blade into the wood.
nWhen the base assembly bottoms out against the depth of cut adjustment knob setting, pull back, releasing pres- sure on the spring. The blade will retract from the biscuit slot.
nRepeat this procedure for cutting the mating slot and all required miter joint slots.
nOnce all slots have been cut, place a biscuit in each joint and dry assemble the workpieces. Make sure each joint lines up and fits.
nFinally, 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 as- semble the workpieces.
nClamp the workpieces together until the glue sets up.
