Offset Holes
-
Throughout the installation procedures we will refer to parts with offset holes.
This refers to the orientation of the holes on the board. An offset hole is one that is closer to one
side than it is the other or in other words, it is not centered on the board. I n the procedures you
will be instructed to attach the boards with the holes offset up or with the holes offset down. This
refers to which side of the board the hole/ holes should be closer to. Offset holes up= hole/ holes
will be closer to the top of the board. Offset holes down= hole/ holes will be closer to the bottom
of the board. Note: some parts do not have offset holes, but instead the holes are on center.
Therefore there will not be any reference to how to offset these parts.
EXAMPLE OF OFFSET HOLES UP
Counter-sunk holes-
Many of the parts that will be used have counter-sunk holes. A
counter-sunk hole is one that surrounds one side of a thru hole, but does not extend through the
wood it’s self. When using a counter-sunk hole the bolt will be inserted through the thru hole and
either the head of the bolt and washer or nut and washer will occupy the counter sunk hole.
Lag Screws-
Lag screws are used in the construction of our play sets to enhance the
structural integrity of the unit. There will not be predrilled holes in the post for lag screw
installation. Lag screws are self-tapping, though if you are using a manual socket wrench it may
be necessary to tap the head of the lag screw with a hammer. You should also be sure to tighten
the lags completely. Power tools such as an impact wrench or power drill should have enough
torque to drive the lag screws without using a hammer, but make sure not to over tighten as this
can cause the threads to “ strip out” in the post.
