Installing Track by Drilling and Tapping
Start at one end of track and work down: drilling, tapping and screwing. Do not drill and tap
both track ends and then expect to drill and tap the center holes.
Clamp or duct tape track in place on mast. Center punch hole being careful to locate center
of track hole.
Drill through track hole, making sure drill is perpendi-
cular to face of mast. Take care to not let the chuck hit
the track. Tap threads and install screws using blue
Loctite
® .
Aligning track at joints: The 1786 splice pieces will help
align the track as you are installing the track. In addi-
tion, use round rods or dowels to align tracks. Use
spring clamps or “C” clamps to hold them in place
until the track is drilled, tapped and screwed in place.
Follow instructions on page 9 regarding loading cars
and installing bottom track.
Tip: For accuracy and ease of punching use a spring loaded machinist's center punch. Use
the narrow shaft model with a centering tube fashioned from a piece of plastic tubing.
Required Parts
Before You Remove Old Track
Before taking old track off, scribe a pencil line down either side of
track to use as a guide for keeping track straight. If the track is off
the mast, use a string attached to the mast to help line up the track
while installing.

See page 3, Determining Track Length. The bottom track length
needs to be short enough to remove easily to put cars on or
take them off the track. We recommend an 18” to 24" (457 mm
to 609 mm) bottom track length.
Do not use 1816 track for
drilling and tapping.
