Part of Unit: Beginning and Advanced Projects
Lesson Plan Overview / Details
This project allows students to practice laminating strips of wood together to make a larger piece of material and is similar to making a laminated cutting board except that the student will be cutting out a round shape and fastening it to a metal rotating piece of hardware often referred to as a "Lazy Susan".
This project allows for the student to be creative with the selection of materials and if desired, an opportunity to customize the overall size of the lazy susan. This is a great project to introduce before thanksgiving and makes a great holiday gift.
A measured drawing is attached for student use.
Note: Six inch and four inch lazy susan hardware components can be found in numerous catalogs, at local hardware stores, or online.

Objectives and Goals
- Students will be able to select the right amount and type of material.
- Students will be able to demonstrate edge or face grain laminating.
- Students will be able to read and interpret the drawing.
- Students will be able to layout the lazy susan.
- Students will be able to cut and assemble the parts of a lazy susan.
Activities in this Lesson
- What is it? - Hooks / Set
Show the video link below of Bill Murray and the Saturday Night Live group about to have Thanksgiving day dinner. Ask the class if they can relate to this video and how many of them eat together as a family and how often they do so. Engage in conversation about the importance of sharing meals together. Discuss how to set a table and where the flatware goes. Have fun getting input from the class. Mention that there is an item that used to be found on the table that is often missing today. Bring out a model Lazy Susan and ask the class what it was used for. Help the class to get a good understanding of how the lazy susan can be both decorative and useful at the dining room table. Let the class know that this would be great at the thanksgiving table or make a great Christmas gift.

- The measured drawing - Lecture
Place a drawing in front of the class using an overhead projector, a document camera, or project the attached drawing below. Briefly identify the parts and go over the measurements of the lazy susan.
Check for understanding through oral questions and allow for student questions.
- Selecting and preparing material for the top. - Demo / Modeling
This project starts out similar to making a laminated cutting board. If you have previously presented a lesson on making a laminated cutting board then skip to the next activity. If not, then proceed to do the following.
1. Show the students how to find narrow strips of material most likely from the scrap bin and note that mixing wood species adds to the overall effect of the project.
2. Demonstrate how to joint and rip sufficient material to uniform widths or random widths to add to the visual effect.
3. Demonstrate how to cut all the pieces to rough length.
4. Show the class how to arrange the strips by mixing and matching the wood species as desired and how to arrange face grain up or edge grain up depending on the desired effect. Show the class how to label the pieces so that they can be placed back in the correct order should they get mixed up. Note that no two lazy susans will look alike.
5. Demonstrate to the class how to dry clamp the strips together by alternating three bar clamps (two under and one on top) to provide holding power.
6. Demonstrate how to apply a thin layer of glue to both surfaces of all the pieces and how to apply pressure from the middle clamp to the outside clamps.
7. Tell the class to let it dry overnight.
Check for learning and allow for questions.
8. Take a previously glued board and demonstrate scraping the dried glue.
9. Demonstrate belt sanding across the grain and with the grain to clean the surface of the board. Note: some instructors will prefer to skip this step and proceed to the surface planer or wide belt sander.
10. Show the class how to finish sand the two faces with an orbital sander.
The board is now prepared. Check for learning and allow for questions.
- Making the top round. - Demo / Modeling
Most likely this will be day two of the lesson plan. Continue by:
1. Locating the center of the laminated board.
2. Using a large compass layout the desired size of the circle. Press hard on the center point as you will need the center mark later.
3. Demonstrate to the class how to cut out the circle using a jig saw, scroll saw, or a band saw. Explain to the class that this requires good eye to hand coordination and that practicing on scrap wood is a must. Tell the class that they should cut close to the drawn circle but that they should not touch the line.
4. Show the class how to sand the rounded edge to the line with a disc sander.
5. Show the class how to round over the edges with a portable router or a table router.
6. Show the class how to finish sand the edges.
The top is now finished. Check for learning and allow for questions.
- Making the base. - Demo / Modeling
1. Describe to the class that the base will not be seen when on the table as it is slightly smaller in diameter than the top and therefore can be made out of most any type of material. I like to use 1/2 inch Baltic Birch plywood as it looks good and introduces the use of plywood. Take the appropriate time to discuss plywood; how it's made, where it is best used etc.
2. Demonstrate squaring a piece of material for the bottom, laying out the circle and cutting it round the same way the top piece was made round. Round over the edges and finish sand like the top as well.
3. Show the class how to layout the location of the access hole and how to drill this hole at the drill press.
The base is now finished. Check for learning and allow for questions.
- Bringing the top and base together. - Demo / Modeling
1. Demonstrate to the class how to layout the locations of the pilot holes for the lazy susan hardware for the top piece.
2. Do the same for the pilot holes on the bottom piece noting that the distance from center is less on the bottom piece. Make sure to note that the distance from center for the pilot holes on the top is the same distance from center as the access hole is on the bottom.
3. Demonstrate drilling the pilot holes at the drill press using the depth gage.
4. Screw the lazy susan hardware onto the bottom first, then using the access hole screw the lazy susan and bottom piece onto the top.
5. Test to see of it rotates properly.
6. Dismantle the project and follow your steps for applying your desired top coat finish.
7. Reassemble the parts together when the protective finish is dry and the project is complete.
Check for understanding and allow for questions.
- The final spin! - Closure
You may wish to close this lesson by reviewing all the steps necessary to make a lazy susan and having the students write a plan of procedure. One way to do this is to have the students call out each step as you guide them. Another method might be to break them up into small groups for a cooperative learning assignment and let them recall the necessary steps. A fun way might be to simply scramble the steps and have the class write them down in the correct order.
- Assessment Types:
- Projects, Writing Samples, oral questioning
Oral assessment should be on-going as the lesson unfolds. Check for understanding by asking questions about the measurements found on the drawing. Ask questions like, "What is the purpose of the access hole and why are the pilot holes for the top in a different radius as compared to the bottom." These are just some examples.
Have the class list the steps (a plan of procedure) needed to make the lazy susan and collect it for evaluation.
Evaluate the project when finished using your standard method for grading projects that meets your needs for grading.
