Things You'll Need:
- Large piece of cherry wood
- Drill
- 1/4-inch drill Bit
- Engineering compass
- Band saw
- Hole saw
- Pencil
- Ruler
- Wood glue
- 1/4-inch-diameter x 4-inch-long dowel (center pin)
- 1/4-inch-diameter x 2 1/2-inch-long dowel (slide lever pin)
- 3/4-inch x 3/4-inch dowel pin
- Mason jar
- Gumballs
- Wood finish
- Clamp
- 3 3/4-inch-diameter lathe faceplate
- Roundhouse chisel
-
Step 1
Set your wood onto your work surface, and grab your engineering compass.
-
Step 2
Measure out your base disc by using your compass. Create a circle that is 6 1/4-inches in diameter and 3/4-inch thick.
-
Step 3
Measure out your body disc by using your compass. Create a disc that is 4 3/4-inches in diameter and 3/4-inch thick.
-
Step 4
Measure out your body ring disc by using your compass. Create a circle that is 4 3/4-inches in diameter and 3/4-inch thick.
-
Step 5
Measure out your second body disc by using your compass. Again, create a circle that is 4 3/4-inches in diameter and 3/4-inch thick.
-
Step 6
Measure out your top ring disc by using your compass to create a 4 3/4" diameter by 3/4" circle.
-
Step 7
Cut out each piece with your saw, in order, labeling them from A through E and marking off the center points of each.
-
Step 8
Drill a 1/4-inch hole in parts A through E using the center dot as your guide.
-
Step 9
Stack the discs labeled B, C and D together with disc B on the bottom and place in your clamp. Measure 3/4-inch from the center of the stack and drill a 5/8-inch-diameter hole through disc C and D, but only halfway through disc B.
-
Step 10
Mark a 2 3/4-inch arc on the curve of disc C. Mount disc C over the drill bit at a 90 degree angle. Using the router attachment on your saw, route out a 1-inch-deep groove to connect the 1/4-inch holes you just made. Do so in 1/8-inch passes to make a smooth cut.
-
Step 11
Cut out the center of disc C and disc E using a 2 1/2-inch hole saw. Drill a 1/4-inch-diameter x 3/4-inch-deep hole in the center of the scrap wood from disc C next to the 5/8-inch vertical hole.
-
Step 12
Chamfer the 5/8-inch-diameter holes on discs C and D using a 1-inch countersink bit.
-
Step 13
Drill a 5/8-inch-diameter hole on disc B.
-
Step 1
Add glue to the center pin and insert into disc A.
-
Step 2
Add wood glue to discs B and A and line up the return on disc B with the "dimple" you made on disc A, and clamp.
-
Step 3
Place the "scrap" piece from disc C over the center pin.
-
Step 4
Drop the outer ring of disc C (with the groove) into place.
-
Step 5
Align the 5/8-inch holes that we made in discs B and C.
-
Step 6
Insert the slide lever in to the 1/4-inch hole in the edge of disc C.
-
Step 7
Adjust the outside C ring to place the lever at the left-hand side of the slot. Mark the outside of the ring and glued assembly.
-
Step 8
Remove the slide lever and glue the ring in place. Do get any glue on the inside of the C disc.
-
Step 9
Slide the lever all the way to the right of the slot, once the glue has set.
-
Step 10
Locate disc D by aligning the 5/8-inch holes. Glue disc D into place.
-
Step 11
Glue disc E into place.
-
Step 12
Clamp the base assembly and allow to the glue to dry for one full day.
-
Step 1
Attach a 3 3/4-inch-diameter lathe faceplate to your saw, and mount your base assembly to it.
-
Step 2
Turn the top first, making a recess the same size as the mason-jar lid both in diameter and depth.
-
Step 3
Use a roundhouse chisel to complete the boring.
-
Step 1
Sand the entire assembly.
-
Step 2
Make the slide lever knob by drilling a 1/4-inch-diameter by 1/2-inch-deep hole in one end. Glue the lever into the knob and allow it to dry. Mount the slide lever assembly in your drill chuck and “turn” the piece. Glue the lever assembly into place.
-
Step 3
Apply wood finish.
-
Step 4
Add gumballs to mason jar.
-
Step 5
Insert mason jar into gumball machine.
