About
The PDF Drawings
Summary
Use these
PDF
(Portable Document Format) drawings if you want
to PRINT the drawings.
PDFs generally will print sharper than the JPGs
or GIFs that are shown
in the previous sections.
Which Drawings To
Use
There are
approximately 22 drawings in the Model 402
4-track PDF directory.
The "template"
drawing
Sheet 59 is the key drawing, followed in
importance probably by the
"overall wiring diagram" and the "track layout
drawing". The other
drawings are for additional reference.

Assembly Manual

is currently not a Step by step instruction
manual for this Model 402,

manuals for the 2-track
unit, and the expansion of the 2-track unit to
4 tracks.

Other
Comments About The Drawings
When To Use
The Model
401 (1651
& 1653) Templates (instead of using
these Model 402 drawings)
If
you
already have a 2-track unit built per the
Model 1651 design, then you
can add the #1653 Helper Control Unit to
expand from 2 tracks to 4
tracks, as described in Section D1, 4 Track
Expansion.
Too Many
Drawings ??
People
sometimes
complain that my drawing sets have too many
drawings, and
they are too confusing. The template drawing
is the 'key' drawing. You
could just use this drawing, and IGNORE the
others. The other drawings
are reference drawings - photos, track
layout, schematics, initial
conditions for operating, parts lists,
building dimensions, signal
layout.
Drawing
Confusion ??
These
drawings can be somewhat confusing, as they
have evolved from one
design to another design, and their usage
overlaps from one unit to
another unit. Assuming you are in the
continental United States, the
easiest way may be for you to call me on the
telephone using the
contact link at bottom (or email me a US
phone number), and I can call
you and give you my opinions, based on what
you want to construct.
