If you are installing the Flip jack foot
on a square jack you cannot use the
guide holes pre-drilled in the Flip to locate the pilot holes
as you can with a
round jack. The hole must be drilled free hand, or by removing the jack from the
trailer and using a drill press.
Looking at the driver’s side face of the jack,
measure up from the bottom of the inner jack
tube 1–1/2” and scratch or draw a mark. Then
measure 1/2 the distance between the front and
back faces of the tube and scratch or draw a line
that crosses the first.
This should be at 7/8” from both the front and
back on a 2” square jack with a 1-3/4” inner jack
tube.
Repeat this process for the passenger side face of
the inner jack tube.
Use a center punch to make a mark at these
locations on both sides of the jack.
Drill two 3/16” pilot holes on both sides using
these punch marks as a guide to start the hole.
Switch drill bits, and use a 1/2” bit to enlarge both pilot holes. Pass the drill
bit completely through the jack to make sure the 1/2” installation bolt will fit
smoothly.
