Boy Scout Merit Badge
MODEL DESIGN AND BUILDING
- Study and understand the requirements for personal safety when using such
modelmaker hand tools as: knife, scissors, handsaws, scratch awl, files,
hammer, screwdriver, hand drills and drill bits, pliers, and wire cutters.
Know what precautions to take when using flammable or hazardous products such
as: glue, epoxy, paint, thinners, and proper protective equipment such as
goggles to be used when grinding or drilling. Discuss these with your
counselor and tell why they are important before you begin your model-making
- Explain the uses for each of the following types of models: architectural,
structural, process, mechanical, and industrial. Do research into the
different types of materials that could be used in making these models.
- With your counselor's advice, select a subject from requirement 4 for your
model project (no kits). Prepare the necessary plans to the proper scale, a
list of materials to be used, and a list of the required tools. This model
should be your own original work. Tell why you selected this subject.
- Do ONE of the following:
- Architectural Model
Build a scale model of a house you select
to a scale of 1/4"=1'0" (50:1 metric). Discuss with your counselor the
materials you intend to use, the amount of detail required, house outside
treatment (finish, shrubbery, walks, etc.) and color selections. After
completion of the model, present it to your counselor for approval.
- Structural Model
Build a model showing corner construction of
a wood frame building to a scale of 1 1/2"=1'0" (8:1 Metric). All structure
shown must be to scale. Cardboard or flat sheet woodstock may be used for
sheeting or flooring on the model. Review with your counselor the problems
you encountered in gathering the materials and supporting the structure. Be
able to name the parts of the wall section, such as: stud, sole plate,
bridging, rafter, subfloor, girder, and joist.
- Process Model
Build a model showing the plumbing system in
your house. Show hot and cold water supply, all waste returns, and venting
to a scale of 3/4"=1'0" (15:1 Metric). Talk to your counselor about how to
begin this model, present the scale and the materials you will use. After
completion, present the model to your counselor and be prepared to discuss
any problems you had building this model.
- Mechanical Model
Build a model of a mechanical device that
should use at least two of the six simple machines. After completion of the
model, present it to your counselor. Be prepared to discuss materials used,
the machine's function and use, and any particular difficulty you may have
- Industrial Model
Build a model of an actual
passenger-carrying vehicle to a scale of 1"=1'0" or 1/2"=1'0" (10:1 or 25:1
Metric). Take the dimensions of the vehicle, and record the important
dimensions. Draw the top, front, rear, and sides of the vehicle to scale.
From your plans, build a model of the vehicle to scale. From your plans,
build a model of the vehicle and finish in a craftsmanlike manner. Discuss
with your counselor the most difficult part of completing this model.
- List at least six occupations in which modelmaking is used and discuss
with your counselor some career opportunities in this field.
