When it comes to woodworking, precision is key. If you’re using a circular saw, a straight edge is essential to ensure that your cuts are accurate and clean. But what can you use for a straight edge with a circular saw? In this article, we’ll explore some options.
Option 1: A Store-Bought Straight Edge
One of the easiest options is to purchase a straight edge specifically designed for use with a circular saw. These straight edges are typically made of aluminum and come in a variety of lengths. They have a lip on one side that hooks onto the edge of your material, and the other side is perfectly straight.
Store-bought straight edges are a great option because they are designed specifically for use with a circular saw, so you can be sure they’ll work well. They are also typically very durable and will last for years.
Option 2: A Piece of Plywood
If you don’t want to spend money on a store-bought straight edge, you can easily make your own using a piece of plywood. Simply cut a strip of plywood that is wider than your circular saw’s base plate, and make sure that one edge is perfectly straight. Then, clamp the plywood to your workpiece, making sure that the straight edge is aligned with your cut line. You can then use your circular saw to cut along the straight edge.
This option is great because it’s cheap and easy to make. However, it may not be as durable as a store-bought straight edge, so you may need to replace it more often.
Option 3: A Metal Ruler
If you don’t have a piece of plywood handy, you can also use a metal ruler as a straight edge. Simply clamp the ruler to your workpiece, making sure that the straight edge is aligned with your cut line. You can then use your circular saw to cut along the ruler.
This option is great because metal rulers are typically very durable and will last for years. However, you may need to use multiple rulers if you’re cutting a long piece of material.
Option 4: A Level
Another option is to use a level as a straight edge. Simply clamp the level to your workpiece, making sure that the straight edge is aligned with your cut line. You can then use your circular saw to cut along the level.
This option is great because levels are typically very straight and durable. However, they may not be as wide as a store-bought straight edge, so you may need to use multiple levels if you’re cutting a wide piece of material.
Conclusion
As you can see, there are several options for what you can use for a straight edge with a circular saw. Whether you choose a store-bought straight edge, a piece of plywood, a metal ruler, or a level, the key is to make sure that the straight edge is aligned with your cut line and clamped securely to your workpiece. With a little practice, you’ll be making accurate and clean cuts in no time!
