In this video, I make one bench grinder. I need this to use in chisel sharpening, blade sharpening, drill sharpening and so on. To do this bench grinder, I made two wooden wheels. One is made of hardboard and the other is made of MDF. I attached a piece of the sanding belt to the hardboard wheel. With this it was very easy and simple to sharpen chisels and drill bits. I applied some metal polishing paste to the MDF wheel and I am sharpening my blade. It was great, it cut the paper very easily. The knife is sharpened perfectly.
You don't need a motor to make this machine. You can use the drill in your hand. Because it takes its power from the drill.
