I found this beauty listed on online market place near me for only 50€, had to have it! I always wanted one of this kind of grinders with long shafts. I think it will be extremely useful for quickly cleaning rust off pieces and buffing stuff out like my blades. Since now I made both this operation with small motors (a tiny bench gridner and a washing machine motor with a drill cuck) and it has always been a pain to work on bigger things as the motor or the base often gets in the way of you workpiece. With this extened shaft you can work all around the wheel and being this a mcuh bigger motor than what I am used to it's also nice to have the extra power so I don't stall the motor while pushing hard! Win-win! I just started to list some of the stuff I use for my projects in this amazon storefront: https://www.amazon.com/shop/blackbear...
