TEMPLATE MOUNTING

You can mount the templates in two positions on the jig(s) which allows the production of multiple types of joints
with each template. To reverse a template, loosen the template knobs (C) Fig. D1, remove the template (B) from the
base, rotate it 180 degrees horizontally, replace it on the base, and tighten the template knobs.
NOTE: Secure the templates by inserting the template brackets (A) Fig. D2 between the large template knobs (B)
Fig. D2 and the brass adjustment knobs (C). You can then make front-to-back adjustments by loosening the large
template knobs (B) and rotating the brass adjustment knobs (C).
