Review on 🔧 Ultimate Multifunctional Polisher: Sharpener, Polisher, Grinder All-in-One by Jake Powell

No spring to adjust belt tension, that's a lie! The whole machine was scratched, you can enlarge the picture posted by the seller (it's all scratched, so they don't have the right equipment to make this machine.) If you are thinking of using this machine for fine grinding or polishing, please sanding belts order extra as I received all 600 grit (not as advertised). I use 1000 grit and up for gunsmiths. The link below is for a similar grinder, but I have a fully adjustable pulley, now the belt size is 0.6*13 inches, you can buy better bigger grinding belts and make your own, it's easy to watch youtube videos. Popular sizes are cheaper and you can make several out of one. Oh, it's that you can run the belt backwards. (Yes, the motor rotates clockwise and counterclockwise. https://www.amazon.com/gp/product/B07RGKJ7BM/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1
