Excerpt
Many DIY projects contain some acrylic components, knowing the right tools and techniques to use with acrylic will make DIY projects easier and more successful. One of the main problems in working with acrylic is that it does not transfer heat very well. Always keep this in mind when using tools with acrylic. Heat from a tool will put stress in the acrylic, which may cause crazing later. Remember to always wear safety glasses when cutting, routing or drilling acrylic, because small plastic chips can come flying off of the tool. It is best to begin with small projects to hone your skills before tackling major projects such as building a large tank (sic Aquarium).
