Pachinko Machine part 1
WHAT WILL YOU MAKE?
A vertical pinball game to play with family or friends!
WHAT WILL YOU LEARN?
You will learn to use woodworking techniques such as hammering, drilling, sawing, sanding and careful measurment to fabricate a mechanical game originating in Japan.
STEPS
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 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 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.

Maker Camp Project Standards
Based on NGSS (Next Generation Science Standards)
NGSS MS.Engineering Design
The Next Generation Science Standards (NGSS) are K–12 science content standards.- MS-ETS1-1. Define the criteria and constraints of a design problem with sufficient precision to ensure a successful solution, taking into account relevant scientific principles and potential impacts on people and the natural environment that may limit possible solutions.
- MS-ETS1-2. Evaluate competing design solutions using a systematic process to determine how well they meet the criteria and constraints of the problem.
- MS-ETS1-3. Analyze data from tests to determine similarities and differences among several design solutions to identify the best characteristics of each that can be combined into a new solution to better meet the criteria for success.
- MS-ETS1-4. Develop a model to generate data for iterative testing and modification of a proposed object, tool, or process such that an optimal design can be achieved.
NGSS HS.Engineering Design
The Next Generation Science Standards (NGSS) are K–12 science content standards.- HS-ETS1-1. Analyze a major global challenge to specify qualitative and quantitative criteria and constraints for solutions that account for societal needs and wants.
- HS-ETS1-2. Design a solution to a complex real-world problem by breaking it down into smaller, more manageable problems that can be solved through engineering.
- HS-ETS1-3. Evaluate a solution to a complex real-world problem based on prioritized criteria and trade-offs that account for a range of constraints, including cost, safety, reliability, and aesthetics as well as possible social, cultural, and environmental impacts.
- HS-ETS1-4. Use a computer simulation to model the impact of proposed solutions to a complex real-world problem with numerous criteria and constraints on interactions within and between systems relevant to the problem.
