Step 1: 4 1/2 Inch Grinder

This power tool is commonly found in metal working and welding shops. It uses abrasive discs to grind, shape and buff metal and other materials.

Step 2: Changing the Nut

Unplugging the cord beforehand is always a good first step.  On the side of the grinder gear box, there is a push button lock used to hold the shaft in place. Hold this down and loosen the nut with the accompanying wrench. Different discs can now be put on the shaft. I made this at Tech Shop!

    Hi there,

    Thanks for sharing, I think the first step should be to PULL THE PLUG!!

    Don't want the grinder to accidentally start while you're trying to change the disc ...

    Your fingers / hands won't like it :-)

    Be safe,
