Okay, heres the deal, I teach 7th grade and in class I am often having to put students together for group work, choose people to hand out materials, choose people to collect materials, choose people to participate in demonstrations, etc. Sooooooo to help eliminate all the whining that goes along with some people getting chosen and others not, I decided to build a WHEEL OF DESTINY!! This virtually eliminates the ongoing whining, for if the arrow lands on someones desk number, then it must be their destiny.
In this my first instructable I will teach you how to build your own WHEEL OF DESTINY!! (on the cheap)
Step 1: Gather your materials.
The WHEEL OF DESTINY contains these basic parts:
1 - swiveling caster wheel
several - 2inch-3inch wood screws
2 - 2.5 in bolts with matching nuts
several 3 inch nails
electric jig saw
compound miter saw
metal drill bit
Might need : metal punch (nail set)
Step 2: THE WHEEL
The size of the wheel will determine the size of the many of the other parts of your WHEEL OF DESTINY.
First take a fairly large piece of scrap particle board and find the center by using a yard stick to draw diagonals from the corners.
Next press the awl (or hammer a nail) into the center, and tie a string around it. On the other end of the string, tie a pencil. This is your make-shift compass. The string will be the radius of your circle so be careful as to how long you make the string. Mine is 10.25 inches (for no particular reason).
Once the circle is marked out, it is time to fire up the old electric jig saw and cut that circle out!
(Of course if time is an issue you could always run down to the local Home Depot and buy a particle board circle - BUT WHAT FUN WOULD THAT BE?! )
Once your circle is cut out it is time to add the nails around the edge (trust me it is a lot easier to do it at this stage of the game). Be sure to space them out evenly. I like to continually divide the spaces in half. This will leave you with 32 equal spaces around your wheel. Mine are spaced roughly 2 inches apart. Of course if you are making a BIG wheel you may want more nails.
Step 3: Brace yourself
The support arm for your WHEEL OF DESTINY should be the diameter of your wheel plus 4 - 6 inches. You need to be sure to give it an inch or two of clearance on the bottom and some room on the top for the selector to be mounted.
Using 2 wood screws attach the arm to the base so that the short side of the 2x4 sits flush against the back of the base.
Using a miter saw cut 45 degree angles on three pieces of scrap 2x4 to make the arm braces. Use wood screws to attach them to the arm and the base.
Step 4: Spin that wheel!
First you must get rid of the wheel. Use the electric drill to drill out the axel of the caster (you may need to use a metal punch or nail set to your drill bit a place to get started). Be sure you are using a drill bit that is made for metal. If this is not working use and electric grinder to grind off one end of the axel. Once one end has been ground off or drilled out, the axel should slide out the other side and you can remove the wheel.
Now attach the mounting bracket to the center of the BACK (the side without the nails sticking up) of your circle. Use the diagonal lines you made for finding the center of your circle as a guide, and then screw it into place.
Step 5: Attach the wheel to the arm.
Step 6: Making and attaching the selector
Use a scrap piece of 1x4, plywood, or particle board and cut out an arrow using the jig saw (if you happen to have one a band saw works great for this). The arrow needs to be long enough to reach down about an inch or two into the wheel area.
Drill a hole where you want the arrow to pivot that is well big enough for the screw, that you are going to use to attach it, to fit. You do NOT want the attachment screw to impede the movement of the arrow.
Attach the arrow to the arm extension, being sure that it is allowed to swing freely.
Step 7: Paint and decorate
It helps to make clear lines on your wheel divisions.
Be careful not to get paint, saw dust, etc. in the spinning mechanism.
- Add velcro to the wheel and then easily change the circle designs.
- Extend the arm and base for a floor model.
