- Eye protection
Step 1: Safety first!
Before starting any project involving power tools, it’s important to prioritize safety. Make sure to wear protective eyewear at all times to shield your eyes from any potential sparks or debris. Additionally, ensure that the bench grinder is properly secured to a stable surface and that the vise is securely holding the blade.
Step 2: Clean the blade
Begin by cleaning the old circular saw blade to remove any built-up dirt, pitch, or rust. This can be done using a wire brush or a solution of warm water and dish soap. Dry the blade thoroughly before moving on to the next step.
