7. Answering Common Questions
7.1. What plastic is best for gears?
The best plastic material for gears depends on the specific application requirements. Polyoxymethylene (POM), Nylon (Polyamide), Acetal, and Polycarbonate are commonly used materials for gears due to their high strength, wear resistance, low friction, and dimensional stability.
If you want to make small plastic gears, you can follow these steps:
- Trace a gear pattern on a sheet of plasticard with a pencil. You can use a compass and ruler to draw guidelines. You can also find some gear patterns online or use a gear template.
- Cut around the gear with a pair of scissors, leaving some extra plasticard around the pattern. Do not cut the individual gear teeth with the scissors, as this could result in uneven or warped gears.
- Cut the teeth out of the pattern with an X-Acto knife. Start from the corner of a gear tooth and move outward. Follow the pattern exactly and be careful not to cut yourself.
- Sand the teeth of the gears gently with sandpaper to remove any excess plastic and refine the shape. You can wrap the sandpaper around a thin metal bar or ruler to make it easier.
- Clean the gears and match them together to make sure they fit. You can use a pencil or another long cylinder to spin them against each other and check their movement.
You can also watch some videos online that show how to make plastic gears at home with different materials, such as wire case or cardboard.
