- Study and understand the requirements for personal safety when using such modelmaker
hand tools such as:
knifeknives, scissors,handsaws, vices, files, scratch awl,hammers, screwdrivers, files,hand drills and drill bits, pliers, and wire cuttersportable power tools, and when to use protective equipment such as goggles when grinding or drilling. 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 wh y they are importantthese with your counselor before you begin your model-making project and tell why they are important.
- 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:
- Make an architectural model.
Architectural Model:Build a scalemodel of a house you selectto 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, houseoutside treatment (finish, shrubbery, walks, etc.) and color selections. After completing completion ofthe model, present it to your counselor for approval.
- Build a structural model.
Structural Model: BuildConstruct a model showing corner construction of a wood frame building to a scale of 1 1/2"=1'0" (8:1 Metric). All structures shown must be to scale. Cardboard or flat sheet wood stock 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 floor and wall frames section, such as intermediate girder, joist, bridging, subfloor, sill, stud,sole plate, stud and bridging,rafter , subfloor, girder, and jois t.
Make a process model.
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, and 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.
Complete a mechanical model.
Mechanical Model:Build a model of a mechanical device that uses should useat least two of the fivesix simple machines. After completing the completion ofthe 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 encountered.
- Make an industrial model.
Industrial Model:Build a model of an actual passenger-carrying vehicle to a scale of 1"=1'0" or ½" = 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 the thismodel.
- Make an architectural model.
- Build a special-effects model of a
fantasy spacecraft that might appear in a Hollywood science-fiction
movie. Determine an appropriate scale for your design - one that makes
practical sense. Include a cockpit or control area, living space,
storage unit, engineering spaces, and propulsion systems. As you plan
and build your model, do the following
- Study aircraft, submarines, and naval ships for design ideas.
- Arrange and assemble the parts.
- Sketch your completed model.
- Write a short essay in which you discuss your design, scale, and materials choices. Describe how you engineered your model and discuss any difficulties you encountered and what you learned.
