- Toys should be good quality squeaking toys, for longevity.

- Sound checks with the toys should be done beforehand to avoid discomfort.

Step 3: Introduction

Before assembling the Musical Bumpers, separate sub assemblies have to be built and constructed.

The description of every sub assembly in this manual will contain:

• An overview of the needed tools;
• An estimation of the needed time to built the sub assembly; • The steps;

Every step in this manual will be described using the following structure:

• Cautions and warnings (if applicable); • The needed parts; • The actions to perform the step

To make this manual easy to understand, images are used as much as possible.

Step 7: Step One - Cutting

All the metal parts should be cut and sanded before proceeding with other steps.

* The 45° angles for the metal pipe should be at right angles to each other

* The 25° angle for the metal rod should be only be on one side.

* The metal strip should have some extra length for gripping while bending.

Step 8: Step Two - Bending

Bend the metal strip that has been cut with some extra on a Circular Bending Machine.

* The metal strip should be cut to 425 mm length

Step 9: Step Three - Filleting and Drilling
