What Are Some Common Mistakes to Avoid When Using a T Bevel?

When using a T angle, there are some common things that beginners tend to need to correct. These mistakes can result in inaccurate measurements and frustration when completing a project. This section will discuss some of these common mistakes and how to avoid them.

1. Not Tightening the Lock Nut Properly

One of the most common T bevel mistakes is not tightening the lock nut properly. The lock nut secures the blade once you have set it to your desired angle. If the lock nut is tightened enough, the blade may move, leading to correct measurements.

To avoid this mistake, tighten the lock nut firmly after adjusting the blade to your desired angle. You can also use a wrench or pliers to ensure it is securely tightened.

2. Using the Wrong Side of the Blade

T bevels have two sides to their blade – one with a straight edge and one with a beveled edge. The straight edge is used for drawing lines, while the beveled edge is used for measuring angles. You need to use the right side of the blade to get accurate measurements.

To avoid this mistake, always use the blade’s beveled edge when measuring angles. Be careful to distinguish it from the straight edge, especially if your T angle is new and has a sharp blade on both sides.
