Chippers are a valuable addition to the yard power tool arsenal. They can turn brush piles, branches, woody debris and other yard refuse into valuable mulch and wood chips. As you feed the debris through varying size hoppers, powerful blades instantly shred it into smaller chips. You can then spread this mulch around bushes and shrubs to help inhibit weed growth and retain moisture.
When installing in-wall speakers, use a drywall saw to cut the hole. A utility knife will make the cleanest cuts in drywall, but a utility knife can be difficult to control by a non-expert. Electric rotary saws make cutting drywall physically easy, but they too can be difficult to control. A simple, inexpensive drywall saw (about $10 at your local hardware store) is the best bet for beginners. The speaker’s frame will cover up any rough edges.
