Conventional NTRK Frame Construction 
(as seen from below)

Lightweight Frame Construction

1" Styrofoam

Add second frame layer for

Additional styrofoam layer
for deeper contours

Additional cross member

Sufficient clearance for
C-clamps required

The  basic  module  construction  follows 
NTRAK  specifications.  Every  module  is  to 
have  four  legs  and  be  free  standing  to 
simplify  setup  and  teardown.  Modules  can 
have a 1" layer of Styrofoam as deck sheet. 
Special care must be taken for the module 
to  remain  sufficiently  stable.  It's  a  good 
idea to have a sheet of luan plywood on the 
underside  to  prevent  "punching  through" 
while handling the module. Remember that 
when  modules  are  clamped  together  that 
small 

gaps 

usually 

are 

filled 

by 

"scrunching" sets of modules together.

An 

additional 

cross 

member  in  the  middle  of 
the module adds a lot of 
strength  and  stiffness, 
without  adding  a  lot  of 
weight.

Make  the  cross  member 
slightly  smaller  than  frame 
so  modules  will  not  harm 
each  other  when  stacked 
and cut holes for wiring.
