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.)

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.
