Things You'll Need
Instructions
Draw the design you want on the birch wood. Birch is great for whirligig kids projects because it is light, soft and inexpensive. Draw anything you want, though bear in mind that all of the details have to be cut out of the wind. Start simply and as you get more advanced, create other whirligigs with more detail. For example, if you want a fish design, draw the outline of a fish with eyes rather than every scale on the fish.
Put on your safety goggles. Lay the birch wood in the jigsaw.
Place your wood on the scroll saw. If you are using a jigsaw to cut the shape, use clamps to suspend the wood so that the reciprocating blade can cut through the wood. Turn on the power saw and cut the shape you drew out of the wood. Follow the lines as closely as you can. When you finish, turn off the machine and sand any rough edges with a rough grit sandpaper, such as 200 grit.
Put the design back in the clamps. Drill a hole through the design where you wish to insert the hardware of the propellers. For example, if you have a fish, drill near the center of the fish where the propellers, which are like spinning fins, are to go.
Insert the axis that come with the propeller kit through the hole you just made. Connect the propellers to the axis by following the instructions of the kit. If you want to paint the wood and the propellers, do so before putting the propellers on the design.
Drill a hole through the bottom of the design. The pole is going to go through this hole. Make sure the hole is wide enough to fit the pole you bought. Mount the whirligig, propellers and all on the rod. Stick the rod outside in the yard, on a patio, or anywhere else and watch the wind move the propellers.
