Project Assessment


Rubric for Woods Project


Criteria
Total Points Possible Student EvaluationTeacher
Evaluation
Plan execution/Accuracy   
(How close does the actual project represent or follow the original plan.  Parts are ripped and cut to precise specifications.)
20

Part Preparation  

(Parts are planed, jointed, and sanded to consistent thickness.  Mill marks are removed.  Cuts are straight, clean, and consistent.) 
20

Dado and Rabbit joints 
(Joints are glued snugly and securely, and are cleaned of excess glue and wood chips.  Joints do not have gaps or voids.) 
20

Assembly
(Project is sturdy and secure. Sides, shelves, tops, and bottoms are aligned flush and tight.  Project is square.)  
20

Work Ethic 
(Students are required to work productively and  cooperatively, daily.  Students will work safely and will partake in lab clean up efforts.)

Examples of Good and Poor Quality Work


This is a good example of what an assembled project should look like.


This is an example of a poorly aligned false top and side from front view. It can be fixed by sanding smooth.


This shows how false top and side should be aligned from front view.


This is a poor example of how the false top and side should be aligned from the back side view. this will result in a space or gap between the back panel and the side. the shelf will bow out the back panel.


This shows how the false top and side should line up from the back side view.



This is a good example of how the shelf should align with the side. They should be flush. The shelf should also fit snugly into the dado or groove.

Assembly



After sides, shelves, bottom, false top, and top are cut to desired length, width, and thickness a dry assembly should be performed to make sure all pieces fit correctly. After dry run, apply glue all dado's and rabbits, align parts and clamp using bar clamps. Next wipe away all excess glue and check project for square and make adjustments as necessary.

Shaper




Use the shaper that is already set up to cut 1/4" rabbits for back panels.

Router and Jig to cut Dados and Rabbits



The router and Jig can be used to cut rabbits and dados for false tops and shelves in veneer plywood. For solid wood use the table saw set up with dado blades.

Cross-Cutting Using the Panel Saw



Cross-Cut wider boards using the panel saw to desired lengths.

Ripping Boards on the Table Saw



Using the table saw again, rip the glued board to desired width.

Time Saver Sander



Use the Time Saver sander to finish sanding boards to desired thickness.

Planning Boards



After Gluing Scrap any glue and plan both surfaces of the board using the planner.

Gluing Boards



Following ripping and crosscutting boards is gluing. Apply liberal amounts of glue, clamp every six to eight inches, and clean up excess glue.


After boards are ripped they are cross-cut using the radial arm saw to rough lengths.

Ripping Boards on the Table Saw



After edges are jointed boards can be ripped on the table saw.

Jointing Boards



First select the species of wood you are going to make the project out of. Select boards that are not warped, bowed, cracked, and twisted. Because material comes rough sawed edges and surfaces need to be planned and jointed. After selecting boards edges need to be jointed using the jointer. The jointer is used to square and straighten edges of boards so they can be ripped and glued.

Lesson Plan 

Lesson Plan 


Name: Jonathan Scally Department: Technology Course: Woodworking 1 


Title: Veneer Edging 


Standards:  


Standard 19: Students will develop an understanding of and be able to select and use manufacturing technologies.


BM M: Materials have different qualities and may be classified as natural, synthetic, or mixed.


Standard 20: Students will develop an understanding of and be able to select and use construction technologies.


BM K: Structures are constructed using a variety of processes and procedures. 


BM N: Structures can include prefabricated materials.


Objectives: 

  • Students will recall what veneer edging is and what are some different applications for it.

  • Students will recognize that there are a variety of materials and processes for accomplishing manufacturing and construction tasks.

  • Students will be able to apply a veneer edge to a piece of plywood or project.

Materials:  

  • Iron 
  • Roller for applying edge
  • Plywood
  • Veneer edging
  • Laminate trimmer to trim excess 
  • Disc sander/hand sand paper

Motivation:

Remind students that this process is being used today in industry and it is important to understand that new technologies are always changing the way construction and woodworking is done.


Procedure:


Introduction to lesson:

  • Attendance 
  • Reflect on information cover yesterday 
  • Give motivation 

Lesson:

  • Ask students if they have heard or been exposed to veneer edging.
  • Demonstrate how to apply edging 
  • Ask students to consider the pro’s and con’s of a technology like this.
  • Ask how this might change the manufacturing and construction of wood products

Summary:

Ask student to summarize the process just demonstrated and allow students to ask questions or to give comments.


Assessment: 

Assessment is implementation of product and process into students project and informal assessment of classroom participation.
