Module frame designs

On this page we have some plans for a 4 foot waffle frame and a bottom view of a 8 foot radius curve.
Keep in mind that this is the most basic design, the starting point if you will. The exact dimentions of the frame can be modified, in fact we have only one that looks like the top and bottom 4ft frame drawings. Most of our modules are 8ft long, a few 6ft. The rib spacing and the waffle pattern is often changed to accomodate the attachment of legs.
I have added the negatives of my drawings in place of the originals for easier printing.

side view

The gussets listed as optional should be considered if there is any possibility that the module will be picked up regularly by the sides. (It is often convenient to do so) 

top view

The top of the module is a simple flat deck. Sub-roadbed up to 1/2" thick can be added without causing problems with the alignment holes at the ends. Notice the location of the inner rails. They are placed at 9" and 21" from the front. This location is important because they are directly beneith the track and thay don't interfear with the alignment holes at the ends.

bottom view

The cell pattern seen here can change to accomodate the installation of legs. Cells can have small doors placed over them for storage of things like skirting, rope, etc...

side view

This is what we call a 'double raised end' or DRE frame. This frame is designed for bridges and any substantial scenery below track level. The frame is able to withstand the potentially large tension and compression forces encountered during layout setup (that last 2 inches the group pushes or pulls to line up the layout).Some exanples of DRE frames we have are 'Lazy Creek' and "Vatican City' .

end view

If you look closely you can see that the top deck, both outside rails and the bottom waffle fit around the endplate. This is very important when the frame is under tension when clamping it to another module. If tensile forces are not properly transmitted from to endplate to the rest of the frame, the frame will break apart.


Here is a bottom view of a 8 foot radius outside curve. Two 90 deg. curves, one with the waffle on the bottom and one without. This is indended to give you an idea of how we do curves.
