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.
2. 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.
3. Cut out the shape that you just made.
It should be a rectangular shape with a
pointed end.
4. Apply glue to the bottom of one of the
5. Glue the two end pieces together to form
a V shape that has a 2" opening. The
rounded edges should be at the opening.
6. Glue the pointed piece on top of the V
shape to make a basket.
7. Add a small pile of hot glue to the bottom
8. 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.
9. Now make three more baskets!

to the center of a craft circle. This will be a
spinner on your board.

12. Measure and cut the ends off of two
popsicle sticks so that they are the same
length as the distance measured in step 11.
13. Glue the four ends to the spacer so that
they are perpendicular to each other.
14. Make three more spinners!
15. Measure and cut a 1" piece from your
3/16" dowel.

19. If you are using our template, cut a
piece of transfer paper to match its size.
20. Find where you want the center of your
pachinko game to be and drill a 15/64" hole.
21. Lay the transfer paper down with the
template on top so that the center hole is
above the hole that you drilled.
22. Now trace all of the other drill holes.
23. 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.
24. Measure 5/8" from the edge of one of
the side bumper pieces of wood. Drill a hole
there using the 1/2" bit.
25. 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.
26. Remove the clasp from the
embroidery hoop with the hand saw.
27. Glue a small cube of scrap wood on top

template, or make your own design! Just
make sure that the ball cannot get stuck
anywhere.
