Scale and gauge[edit] (Wikopedia)
Scale refers to the size of the model relative to the actual full-sized object being represented,
while gauge is the width of the model track. Most commercially produced model track is a
compromise between appearance and a trouble-free running surface.
§Scale[edit]
Scale is the ratio of a model dimension to the real life dimension. O Scale in the UK is commonly
1:43.5 or 7 mm to the foot, in continental Europe it is commonly 1:45 though 1:43.5 is also used
particularly in France,[3] and in the USA 1:48.[2] Each region tends to design models to its own
scale.[citation needed] The NMRA and the MOROP maintain detailed standards for a variety of scales to
help model makers create interoperable models.[3][4]
§Gauge[edit]
Gauge refers to the distance between the inside edges of the load-bearing rails. Various sizes
of track gauge exist around the world. Standard gauge is 1,435 mm(4 ft 8 1⁄2 in).
Regional model manufacturers design their O-scale rolling stock with minor regional scale
differences —— manufacturers support their rolling stock with track made to the same regional
scales, so there is no universal width for O-gauge model track.[citation needed] Models could represent
the real-world standard gauge track spacing of 1,435 mm by choosing various spacings such
as 30
mm (1.181 in) at 1:48 scale, 1.25 in (31.75 mm) at 1:45.2 scale, 32 mm (1.26 in) at
1:44.8 scale, 32.96 mm (1.298 in) at 7mm:1 ft scale, and 33 mm (1.3 in) at 1:43.5 scale. Model
makers choose their scale based on many considerations including the existing marketplace,
aesthetic concerns and compatibility with existing models.
Requirements:

Work in Groups of 4-6. Each student will be required..

Sketch for the cars, tender, locomotive, or caboose.

Dimensioned Drawings for each part of which ever car they have contracted to create.

Assembly drawing.

A built prototype (time permitting).

Coupling: Design from each student.

The group will be required to produce an assembly of the entire train and choose the best
coupling.
OPTION 2- Nesting Boxes:
1. Research a particular native bird (Poland).
Nesting Boxes: Hole and nest box sizes for various birds
2. Choose a particular house that will suit the bird. Other options are
on our website.
3. Sketch the house and figure out the size of each of the parts you
will need to build the house.
4. Create and assemble the parts in Inventor Pro.
5. Create a coversheet and orthographic of all the parts.
Projects will be scored according to the following rubric:
