Cadry Williams - Hardwood Cutting Board

Student:
This lesson was adapted for a student with a visual impairment.  Although legally blind, the student has some vision with the assistance of glasses. She is capable of reading although complains that the latter are blurred. Her glasses are a requirement for any time spent in working in the shop.

Rational:
Normally I would use a pine cutting board for a grade seven class. Pine I a relatively in expensive wood and is consider to b a soft wood. Soft wood usually have open gain meaning, that the fiber of the wood a loosely pack together. However, pine has very little variation in color making it hard to see the direction of the grain. Therefore, I have decided to use oak for the student with a visual disability. Although it is a hard wood, it has an open grain that is readily visible especially in the dark rings of the wood, making really easy to see the direction of the gain.

Final Notes:
No student is allowed, at this level, to use the table saw. All operation regarding it must be done by teacher or teacher in training.

Resources Needed
·      No specialty tools will be needed (All tools can be found in the tool crib) and wood can be found the Wood Room.
Learning plan (Stage 3)
Steps of the lesson   Engagement, Exploration, Terms, Introduction, Content, Application	·   Note: this lesion plan does not include Tool use and safety it only contains instruction of how to complete a cutting Board. (Please refer to individual tool and machine safety lessons for details tool and machine use and safety.) ·   Cutting Board 101 ·   Determine Grain Direction ·   Student should already know the types of grain (Opened and Closed). ·   Go over it if necessary have a variety of wood and hand include Pine, maple, cider, oak and walnut (under the table or nearby). ·   Use the Dog fir analogy to describe why the direction of the grain is important. ·   what happens when: ·    You go against the direction of the grain. ·   You go with the direction of the grain. ·   Ask What do you think will happen if you apply the concept to wood ·   Use wood block and Chisel to illustrate. ·   Smiley vs. Sads face ·     Instructions ·   Have student obtain several pre-cut pieces from the bin. (12-15 pieces) ·   Note: you will have a lot of scrap pieces of wood around occasionally make some pieces (15-17”x ¾” x 1” ) ·   Orientation time ·   Have student line up all pieces face edge up with all gain in one direction. ·   With a pencil mark a double line across all pieces ensuring the gain is correct (Check point 1) ·   Have student use Smiley vs. Sads faces ·   Strengthens Boards and decrease warping ·   Quarter turn all  board in one direction ·   The tighter gain of the edge grain: 1.    Increase Strength 2.    Makes it harder to cut into the board damaging it ·   Gluing ·   Apply s thin layer of glue to the face edge of all pieces except the first and last one. For the first and last one, only apply glue to the side that will be touching another piece of wood ·   Clamping ·   Prep 2 bar clamps prior to gluing ·   Clamp project together and leave it for at least 3-4 hours to dry. (24 hour to cure) Note: with a damp rag remove any excess glue. Note: Several projects can be clamped in one bar clamp at a time. ·   Machining ·   With a scraper remove all excess glue ·   Joint one face then send through thickness planer (Keep it as thick as possible) ·   Using a framing square, a wide scrap board with parallel edges and at table saw cut end gain square with the edge grain. ·   Use framing square and a wide scrap board to cover one side of the projects end grain. Make sure that the outer most edge of the parallel scrap board is perpendicular to the edge grain of the project (ensure that scrap board extend beyond all ends of the project on the side you are working on) ·   Use the table saw to cut the opposite end square ·   Remove board and cut the final end square. ·   Router edges (use ¼ round over bit) ·   Finishing ·   Sand faces smooth (use 80 grit then 120 grit) ·   Stain using  Lin-seed oil or Danish oil
