USING THE

UNDERSCRIBE

TRIMMER

The bottom plate of the

Underscribe Trimmer has a guide lip (see Fig. 17). This guide lip is moved along an installed piece of laminate as the trimmer bit cuts the mating piece of laminate.

The “butt” joint is commonly used in the construction of face frames. Proceed as follows to install a laminate covering on a face frame. Similar procedures would be required for making any “butt” joint.

ALWAYS WEAR SAFETY GLASSES WHILE OPERATING A LAMINATE TRIMMER.

1.Cut the pieces of laminate covering to rough size and apply contact cement to the face frame and the laminate pieces in the normal manner.

NOTE: Cut the rail covering approximately 1" longer than the rail (to allow material for trimming).

2.Apply the laminate to all stiles.

3.Position the laminate to a rail with at least 1/4", and no more than 3/4", overlapping each stile (see Fig. 18). Use a roller to secure the center section of the laminate to the

rail. Leave at least 4" of

the laminate loose, at both ends of the rail (Do not roll down).

4.Securely clamp the face frame assembly to the worktable to prevent movement during the trimming operation.
