OPERATION

T- JOINTS

See Figures 11-15.

A T-joint is used when the end of a board is joined to the face of another board as shown in figure 11. Attaching shelves to bookcases and inner support braces to frames are typical applications. Actual cutting of a T-joint is as simple as any other cut. However, it is critical that you mark the centerlines, mark the intersection points for each slot, and cut each slot correctly. See Figure 11.

HOW TO MAKE T- JOINTS

■Unplug your detail biscuit joiner.

■Place the two pieces of wood to be joined on a level workbench as shown in figure 12. The inside face of the vertical board should be facing up.

■Determine the location of each biscuit joint and mark the centerlines on each board as shown. The centerlines for both boards must line-up with each other. Measure carefully, these measurements must be accurate and precise. TIP: Measure twice and cut once. In addition to the centerlines lining up, the spacing of the biscuit slots from side-to-side must also match.

■Plug your biscuit joiner into power supply and cut slots in all boards that require end slots. See Figure 13. Follow procedures explained in "Edge-To-Edge Joints". Rotate fence angle to 90°, set fence height at desired dimension on the scale, select the correct depth of cut setting for the biscuit size you plan to use, clamp workpiece securely, then cut each slot at the marked centerline intersection.

■Next, you must remove the fence from your biscuit joiner in order to cut slots into the face of the vertical board.

TO REMOVE FENCE:

■Unplug your detail biscuit joiner.

■Loosen height adjustment knobs, pull fence forward and slide it down the front base until it can be removed through the key hole slots. See Figure 14. Next, select the correct depth of cut setting for the biscuit size you plan to use, clamp workpiece securely, and cut each slot at the marked centerline intersection.

WARNING:

When the fence is removed, the cutter may be exposed. Use extreme caution to avoid serious personal injury.

■Place your biscuit joiner on vertical board as shown in

figure 15 and align indicator marks on bottom shoe with centerline on vertical board.

■Place a straight piece of wood on the vertical board and securely clamp it flush against the bottom shoe. This piece of wood is used for a fence or guide. It must be square with the sides of the vertical board and parallel with the centerline.

■Align centerline on bottom of shoe with marked intersection for biscuit slot.
