L-Shaped Layout

["Ira Schneider" <ira_schneider@iname.com>]

I measured the old and new corner modules at New Braunfels and laid out the minimum sized
L-shaped layout.  The first attachment, named "L-Shaped Layout Dimensions", shows the smallest
L-shaped layout we can assemble using two different methods to close the loop.

The first diagram uses special 39" modules.  If we use this method, we would have to
build two 39" modules, which we could also use in a normal layout.  These modules would have
to be either ABCD or ABCE modules, depending on how we build the layout.  If we choose to
build these modules, I would suggest we build ABCD/E modules, where both track positions
D and E are wired to track power 4 (like the corner modules).  That way the special modules
could be used within a section of either ABCD or ABCE modules.

The second diagram uses special 9" modules.  I think we could build two blank 10" modules
(i.e. no tracks, just 10" x 24" x 1/4" plywood with 3" fascia boards to clamp to the adjacent
modules) and use either two sections of our standard 10" bridge track across the module or
special 20" bridge tracks.  If we are going to use special bridge tracks, we might as well make
the modules 9" wide and use 19" bridge tracks, which agrees with the dimensions I calculated.

The second attachment, entitled "L-Shaped Layout", is one possible "real" layout, using the
10" spacers.

Even though this is an interesting exercise, I don't see the point.  The layout I attached
has four (4) fewer modules than a plain 5 x 4 oval and has much less interior room for us to
move around and store our property.  I don't see this as a real selling point for future shows, since
they seem to assign rectangular areas for layouts.

To sum up, in order to assemble an L-shaped layout, we need to:

   1. Add a second set of wiring harnesses to one of the new corner modules to be used as an inside corner
   2. Build two special modules - either 39" ABCD/E modules or 10" spacer modules
   3. Find some place to store the new modules in the trailer

If we want to pursue this, someone should lay out all six corner modules at the next fun run at BCE
and verify my calculated dimensions for the special modules.  (I will be out of town for both the May
and July runs.)  Please make sure you line up the modules properly - the interior corner module
is offset from the adjacent modules.  It will probably be easier to measure the spacing using the
second layout (i.e. with the 9" spacer modules).  If we choose to use the small spacer modules
we also need to decide whether two 10" bridge tracks is stable enough to run across the modules
or if we need special 19" (or 20") bridge tracks.
