Markings on the Benchtop Base
A series of markings have been added to the
Benchtop Base that mark the exit point of the
screw for a given Drill Guide Block setting. These
markings will allow you to "estimate" the exit point of
the screw without needing to know what the actual
thickness of your material may be. These markings
are similar to the lines on a ruler. The longest lines are
labeled as 1/2", 1", and 1-1/2" and the lines that fall
between these labeled locations represent the 1/4"
increments and 1/8" increments (shortest lines).
For example if you want the screw to exit at a
position closer to the inside of your workpiece, simply
mark the desired exit location on the edge of your
board and choose the line on the base of the jig that
most closely corresponds, then adjust the Drill Guide
Block to the same fractional setting height. Once
the Drill Guide Block is secured at that height the
resulting pocket hole will guide a screw to exit at the
predetermined location regardless of the thickness
of material.
Setting the Depth Collar - Benchtop Base
Standard Depth Collar settings are molded into the
face of the Benchtop Base. These drill depths allow
for maximum screw penetration in the mating
workpiece when using the recommended screw
for the size material being joined. To use these
markings align the stepped shoulder of the drill
bit with the desired mark on the base. As the Depth
Collar is moved away from the stepped shoulder of
the Drill Bit the resulting pocket hole will be deeper.
Be careful not to set the Depth Collar so that the
drill bit will penetrate the jig itself.
When departing from the designated drill bit depth
settings for the given material thickness the pilot
point of the drill bit should be kept a height of
approximately 1/8" (the thickness of a nickel)
above the surface.
