Whatis PVC?
Practical
Polyvinyl chloride is a thermoplastic resin characterized by light weight, chemical inertness, resistance to weathering, and electrical non-conductivity. These are excellent qualities for one of its major uses, pipe. They are also good qualities for building assistive technology supports.
Versatile
The pipe can be purchased in several diameters and thicknesses or schedules. The thicker the wall of the pipe, the greater the amount of pressure per square inch that it can withstand from liquids within. The two most common schedules available are 1120 and 40. The thicker Schedule 40 pipe is the best choice for most projects.
There are two other grades of PVC pipe: clear and furniture. Clear PVC allows you to see through it, which may be crucial to some projects. Furniture grade differs from regular PVC in three ways: 1. Ithas titanium dioxide added to it, making it more resistant to ultraviolet light breakdown. 2. It has an impact modifier added to it so that it is less likely to break under pressure. 3. It has a glossy finish.
Cheap
PVC pipe and joint components are widely used in the construction industry. These materials and the tools needed to design and build a wide range of practical, customized devices are readily available. They are also surprisingly inexpensive.

o> Safety First
Atall times, ensure that you have adequate ventilation while working with PVC. Open doors and windows and turn on air circulating systems (fans, air conditioning). If you feel dizzy, intoxicated, or develop a headache while working with PVC glue or cleaner, get fresh air immediately. If the symptoms persist, seek medical treatment. Long-term over exposure can cause permanent nervous system damage.
PVC cleaner and cement are both flammable. Keep them away from open flame at all times.
Do not build weight-supporting devices out of plumbing-grade PVC. Use furniture-grade PVC instead.
Avoid sharp, unprotected edges in designs. Use end caps if possible or sand down edges. This results in a safer, more aesthetically pleasing design.
Do not work with PVC cleaners and cements during pregnancy. Some people have a strong sensitivity to these chemicals and should avoid them altogether.
Always wear dust masks and safety glasses when using power tools, e.g., drills, saws, sanders. It is recommended that you wear safety glasses at all times during PVC work, but especially during cleaning and gluing activities.
Test all PVC welds after assembly. Apply a good amount of force to ensure that the cement has set and the bond is sufficient.
Get help from an experienced person when you aren’t sure what is safe, when something isn’t working, or when you have technical questions.
To ensure safety, routinely examine your equipment before you begin a project.
10. Know your district policies for PVC glue. Some districts do not allow its use in classrooms.

e The PVC Tool Kit
The following materials should be included in a basic multi-purpose PVC toolkit. For storage, consider using a heavy-duty toolbox, large fishing tackle box, or plastic shelving units with sliding drawers. Use a notebook or binder to keep track of inventory and design ideas. While the following designs use %” components, PVC pipe and fittings are also available in '/,”, 3/4”, 1”, and several larger diameters.

/\ Measuring & Cutting
Make accurate cuts by checking your measurements twice before cutting. When designing or copying an existing design, be sure to account for the pipe length used for the joints. Each joint will take °/s-3/,” of pipe on each side, depending on how firmly you join the parts together. End caps use °/,” of pipe. A “T” joint will add an additional 1 °/s” to a pipe.
Plan your cuts in advance so that you have the least amount of waste material possible. For increased accuracy, cut with the PVC cutter blade above the pipe so you can see where the blade comes into contact with the pipe. Placing a %” paper tube over the pipe and holding it in place at the desired length can be a helpful way to line up a cut. The tube can be made by cutting a strip of paper, wrapping it around a 4” diameter pipe, and taping the paper so that it retains its tube shape.
Squeeze and release the cutter several times if necessary to start the cut. Release the cutter after each squeeze to engage the ratcheting effect. If the pipe fractures when you start to cut it, move further down the pipe and start again. Using a fractured pipe could cause a crooked joint or failure of the joint.

Cleaning & Cementing
There are a variety of cements and cleaners that can be used with PVC pipe. For aesthetic reasons it is best to choose one that does not have a dye in it. It can not be stressed enough that proper ventilation is required when working with PVC. Failure to provide proper ventilation can result in over exposure. Please read and follow the recommendations in the Safety First section of this book before undertaking any project using PVC.
When using an angle other than 90 degrees with a T joint, mark the joint with a grease pencil while it is in the proper position before cementing. By lining up the grease pencil line after gluing, the joint will be in the proper alignment. This procedure is explained in further detail later in this book, within the directions of the projects that require its use.
It is a good idea to pre-fit all projects or assemblies prior to cementing the components to confirm size and fit.
Apply the cleaner to both surfaces to be joined first. Then apply the cement to both the pipe and the inside of the joint. Y ou will have about twenty seconds to work before the cement sets. Use a half turn motion when joining the parts to ensure the best bond.
After pressing the pieces all the way together, make sure the union is straight by placing the pipe on a flat surface and pressing the joints so that they are flush with the surface.

Aesthetics: The Final Touch
Y ou may want to improve the appearance of your PVC projects by painting them. The advantage to painting is that it offers some protection from UV light deterioration. The drawbacks are that itis time consuming, scratches easily, and increases the final cost of the project. If the PVC project is to be painted, a spray paint is recommended. The paint will perform better if a coat of primer is applied first. The paint will also resist scratching better if given a few weeks to cure before using the project.
Colored shrink wrap, such as is used in the electrical trade, can be applied to provide a more durable finish than paint. Shrink wrap is applied to the pipe during the construction, since it must be slipped over the pipe. A heat gun is used to apply heat and shrink the wrap to the pipe. This finishing method is somewhat costly. Check with your local electrical supply store to determine the cost and availability of heat shrink materials in your area.

PVC Designs
The following designs have been used in the ATEN workshop on PVC. They range in complexity and the level of skill required. Every device has been used in the field.
We invite you to think of these designs and the basic skills you'll master as you build them as a foundation for developing your own devices that are tailored to the specific needs of the children you serve.
If there is an idea in the book that you like, but you are not able to use that exact design then SCAMMPERR. Look forward to the end of this book, where you can gain ideas on how to modify any design to meet your individual needs.
As you begin to explore the uses of PVC devices, please send us your plans and your comments.

The last step is to assemble and cement the pendulum arm as shown on page thirty-nine. This step requires the following pieces of pipe: one 23 %” and three 1 2” lengths. This step also requires one T joint, one elbow, and one end cap. File the ends of the pipes indicated in the diagram. Place the filed pipe ends into the two open T joints on the upright frame. Do not cement these joints.
Cement the upright frame into the two vertical T joints of the base/ramp.
Attach the release arm to the upright frame by placing the filed pipe end of the release arm into the T joint at the top of the upright frame.
Lift the pendulum arm to the rear of the bowling ball launcher and lock it into place using the release arm. Adjust the angle of the T joint at the top of the upright frame so that the release arm is in its most effective position. Use the grease pencil to mark a line from the T joint to each of the adjoining elbow joints. Remove the release arm. Disassemble the top of the upright frame, cement the T joint in place, and reassemble the upright frame, using the grease pencil marks to align the T joint to the proper angle. Make sure the pendulum is in place before cementing is completed.
Insert the release arm into the T joint at the top of the upright frame again to complete the assembly.
