## Introduction: NIST Design Arthritis Machine

How to create a machine to pour your milk.

This machine was created to help people with all kinds of disabilities, but specifically people with arthritis to complete the task of pouring milk. A "simple" task like this seems easy to people with a full range of cognitive movements and motions but there are some people who have trouble with this. The goal for this machine is to create a machine that solves a small problem someone might face with arthritis.

## Supplies

Supplies:

2 - 19cm by 28.5 cm by 1cm wood board
1 - 19cm by 21.5 cm by 1cm wood board

1 - wooden dowel, 13 cm tall by 2.4 cm diameter

1 - wooden circle, 4cm diameter by 1cm thick

1 - pulley

2 - 24cm by 4.5cm strip wooden wooden board

1 - 23.5 by 4.5 cm strip, wooden board

1 - 10 by 10 cm square

3 - 10 by 7 cm square

1 meter string

A scroll saw

## Step 1: Step 1: Cutting

Each of the items listed on the supplies is needed when creating the project.

Each of the items has the ability to be cut from a basic scroll saw and even a handsaw

2 - 19cm by 28.5 cm by 1cm wood board
1 - 19cm by 21.5 cm by 1cm wood board

1 - wooden dowel, 13 cm tall by 2.4 cm diameter

1 - wooden circle, 4cm diameter by 1cm thick

2 - 24cm by 4.5cm strip wooden wooden board

1 - 23.5 by 4.5 cm strip, wooden board

1 - 10 by 10 cm square

4 - 10 by 7 cm square

## Step 2: Step 2: Glueing

Glueing this machine will take some time because it can take as long as 12 hours for the wood glue to set. The machine should be set up in three different parts.

First,

Glue the two wooden side boards (19cm by 28.5cm by 1cm) to the base board (19cm by 21.5cm by 1cm). This will create a box with two of the sides exposed. This can be seen inside the image.

Second,

You will start glueing the box that will hold the milk. The four pieces (10cm by 7cm by 1cm) are going to be placed on top of the (10cm by 10cm) to create a box.

Third,

The third part that will be added is the base column. This will we placed in the exact center of the base board. On top of the base column should be the 4cm wooden circle.

Fourth,

Now you will take the two pieces (24cm by 4.5cm by 1cm) strips and one (23.5cm by 4.5cm by 1cm) and glue them in a "U" shape with the 23.5cm peice in the inside.

This will then fit over top of the base shape to create a bridge almost.

## Step 3: Step 4: Finishing Touches

Now all of the base shapes and objects have been created it is time to make the final product.

Glue the three columns in the middle of each side of the large box.

After these are dry you will then place the small box on top.

You will connect the pulley to the bridge that was created in the step before. The 1m of string with be fed through the pulley that will then be tied to the smaller box.

Congratulations!

I hope you have enjoyed the experience of creating a machine that will help someone in the world with ha disability have an easier life. Thank you for building my machine and have fun using it!
