Challenge:

Each project is introduced to the student as a “challenge” (rather than a recipe to follow).

Details, constraints, initial ideas go here.

 

Inspiration

 This section links to other related projects (usually other Internet pages) to show students similar projects.

Learning

The purpose of this project is to develop skills and knowledge from using soft-wood and acrylic plastic with hand and power tools. Finishing will be done to accent the silhouette and seal the wood.

Presentation: You will present your self-evaluation to your teacher.  Your project may be put on display within the school and photographed for the school website.

 

CTF Curriculum Outcomes (Alberta Education, Career and Technology Foundations)

2. I use occupational area skills, knowledge and technologies.  

3. I follow safety requirements associated with occupational areas and related technologies.  

9. I create products, performances or services in response to challenges.  

11. I communicate my learning.


 

Learning 

  • Hand tools (metric measuring, files, file card, sanding blocks/paper)

  • Power tools (drill press*, band saw*)

  • Wood (material)

  • Plastic (material)

  • Finishing (markers, water-based varathane)

  • Use metric measurements

  • Student chooses shape/outline

  • Slot has to be diameter of toonie plus (so straight part = toonie diameter and extra half round at each end from drill bit)

  • Curves (half-rounds) actually better as does not concentrate the stress at the corners (aircraft)

    *requires Tool License

Questions 

  1. How did you …?

  2. How did you …?

  3. Why did you …?

Instructions

Step 1 - Planning

  • You will draw sketches of your wooden bank - the following are provided for inspiration.

  • Two dimensional (2D) side view required to be handed in.

  • Other sketches can be included.

  • Planning - print accents on 1:1 drawing.

  • Use accents (e.g. Loon’s neck, frog legs and eyes) with a sealer (varnish) not full paint.

    • A marker may be used instead of paint. (Test on scrap wood to make sure the marker does not bleed on the wood.)

Requirements:

Name: ______________________ Class: _______ Date: ________

  • Full Scale (1:1) side drawing

  • Maximum size ____ cm x _____ cm

  • No thin pieces that might break off

  • Wall thickness minimum ____ mm

  • Outline of acrylic (plastic) shown

  • Accent markings shown in color

  • Dotted line for hidden object line (slot - larger than a toonie)

  • Acrylic - hard and brittle (compare materials to rubber or foam) image

Idea to Sketch to 1:1 drawing to Finished Product

Step 2 - Interior Shaping

  • The inside (interior) is cut out first while the piece is the largest (strongest) to prevent breakage

  • Drill Press License

  • Type of drill bits

  • Series of holes

  • Connecting holes

  • Hand saw (not scroll saw)

  • Files: Rasp, Double Cut, Single Cut - rough, coarse, bastard, second-cut, smooth, and dead smooth

  • Sand (grit of paper)

  • Chamfer edge to prevent breaking

Step 3 - Exterior Shaping

  • Then exterior cut

  • Band Saw License

  • Go / No go Gage (literacy: Gage versus Gauge - share what you know, don’t show off: computer spell checker)

Step 4 - Cut slot

  • Drill ends

  • Drill Press License

  • Caution, breakout - ease off at end of hole (use masking tape to show depth)

  • Then exterior sand/file

Step 5 - Plastic sides

  • Clear acrylic

  • Slight oversize acrylic and file back to final size (and remove cut marks)

  • Drill Press License

  • Twist drill bits (hard and brittle)

  • Pan head screws (no wedge - explain simple machines, cause cracking in acrylic)

  • Drill acrylic - angle on drill / type of drill to prevent cracking

  • Then file edge of acrylic

Step 6 - Finishing

  • Smooth

  • Accents - use markers (as indicated on your original plan) to highlight the surface of you bank.

  • Seal / varnish to protect the wood (from drying out) - need drying rack and secure (lockable) must be water based.  (Varnish is the old material used to seal wood. Now, the word “varnish” is often used as a verb, like “painting”.)
