12.Run all stock to be molded through the machine at this time. Note: If you are molding several boards with the same profile and have to make several passes to complete the profile, you must run all boards through at each setting. This assures all stock will match the desired shape. This is especially important when splicing molded boards together such as crown molding or baseboards.
13.2Back Relief Molding
Back relief molding is used to create a better fit over irregular surfaces. With less wood contact, the molding matches irregular surfaces more easily. The back relief cut is formed on the work piece first; then the workpiece is molded to its finished shape. (Fig. 23)

13.3Tongue and Groove Molding
Tongue and groove molding is accomplished in the same manner as other types of molding. Keep in mind the edge guide must be taller to adequately support the work piece. The edge guides must be set 3/4” below the lowest point the cutter will travel.
Cutting the groove first allows adequate support when cutting the tongue (Figure 24).

14.0Maintenance
Disconnect machine from power source (unplug).
•Keep
•Lubricate table with furniture wax or automotive paste wax for smoother feeding of workpiece. Do not use a lubricant that will affect the workpiece’s ability to accept stains or protective finishes.
•Replace feed rollers, blades, and cutter knives if they become damaged. Sharpen blades and cutters when they become dull.
14.1Lubrication
Disconnect machine from power source (unplug).
•Coat the elevating screws with light automotive bearing grease once a month.
•Lightly coat the chain drive and gears with light automotive grease once a month.
•Lubricate four columns with 10W machine tool oil once a month.
