Ryobi JM82 manual Making T- Joints, See Figures 14

OPERATION

T- JOINTS

See Figure 13.

A T-joint is used when the end of a board is joined to the face of another board as shown in figure 12. 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.

MAKING T- JOINTS

See Figures 14 - 15.

nUnplug the biscuit joiner.

nPlace the two pieces of wood to be joined on a level workbench. The inside face of the vertical board should be facing up.

nDetermine the location of each biscuit joint and mark the centerlines on each board. The centerlines for both boards must line up with each other. Measure carefully; these measurements must be accurate and precise.

NOTE: 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.

nPlug the biscuit joiner into the power supply and cut slots in all boards that require end slots.

Follow the procedures explained in “Edge-To-Edge Joints.”

nSet the fence angle at 90°

nSet the fence height at the desired dimension on the scale.

nSelect the correct depth of cut setting for the biscuit size you plan to use.

nClamp the workpiece securely, then cut each slot at the marked centerline intersection.

Next, you must adjust the fence on the biscuit joiner in order to cut slots into the face of the vertical board.
