STEP 1

Measure and cut 2" from both ends of a jumbo craft stick. Measure 1.25" of the remaining craft stick and cut it to have one 1.25" piece and one 0.75" piece. Measure and mark 5/8" away from the left edge on both the top and bottom edges of the 1.25" piece. Connect each mark to the center of the left edge to form a point.

STEP 2

Cut out the shape that you just made. It should be a rectangular shape with a pointed end. Apply glue to the bottom of one of the first pieces that you cut out in step one.

STEP 3

Glue the two end pieces together to form a V shape that has a 2" opening. The rounded edges should be at the opening. Glue the pointed piece on top of the V shape to make a basket.

STEP 4

Add a small pile of hot glue to the bottom of the inside of the basket. Place the 0.75" piece at an angle on top of the glue to make a small ramp. This will guide the ball into the hole if it lands in a basket.

STEP 5

Now make three more baskets!

STEP 6

Glue one end of the aluminum spacer to the center of a craft circle. This will be a spinner on your board. Measure from the spacer to the end of the circle. Ours is about 0.25".

STEP 7

Measure and cut the ends off of two popsicle sticks so that they are the same length as the distance measured in step 6. Glue the four ends to the spacer so that they are perpendicular to each other.

STEP 8

Make three more spinners!

STEP 9

Measure and cut a 1" piece from your 3/16" dowel. Sand the ends so that they are smooth and flat.

STEP 10

Glue two jumbo craft sticks together so that they are about 0.5" off center. Glue the 1" piece of dowel to the end of one of the craft sticks from step 17.

STEP 11

If you are using our template, cut a piece of transfer paper to match its size. Find where you want the center of your pachinko game to be and drill a 15/64" hole.

STEP 12

Lay the transfer paper down with the template on top so that the center hole is above the hole that you drilled. Now trace all of the other drill holes. They are the green circles on the template.

STEP 13

Drill the holes that you traced. Make sure to sand each hole so that the balls can freely roll in and out of the holes. Measure 5/8" from the edge of one of the side bumper pieces of wood. Drill a hole there using the 1/2" bit.

STEP 14

Glue the bumpers of your game onto the board. Make sure the hole that you drilled in one of the bumpers is on the bottom right when your game is standing straight up Remove the clasp from the embroidery hoop with the hand saw.

STEP 15

Glue a small cube of scrap wood on top of the center of your bottom bumper. Bend the embroidery hoop so that it touches the top, left, and right bumpers. Mark where there is excess hoop on the right side of your board.

STEP 16

Cut off the excess hoop and glue your embroidery hoop down. Glue the bottom edge to the scrap cube. Measure and cut the other hoop so that it connects to the end of the first hoop on the right side of the board and curves to the top. Glue it down.

STEP 17

Cut the 1/8" dowel into four 1" pieces. Put the pieces of dowel into the aluminum spacers on the wheels and mark how far they go in.

STEP 18

Add a small amount of glue to the four wheel holes and hammer each dowel piece in until they reach the marks that you made in step 17. Trace the remaing portion of your template onto the board.

STEP 19

Glue the ball baskets over each ball hole. Be careful not to obscure the holes with glue! Lightly sand the plastic ornament and glue it to the center of your board. You might have to make the ornament shorter using the hand saw Place one spinner on top of each of the four dowels.

STEP 20

Hammer the nails according to the template, or make your own design! Just make sure that the ball cannot get stuck anywhere. Hammer the nails closely together to create the walls that guide the balls into the baskets. These are represented by solid curved lines on the template.

STEP 21

Go to part 2 to find out how to make a ramp, ball tray, stand, and launcher! We will also be adding lights, sounds, and an Arduino to our pachinko game.
