Maicojames i'm guessing oyur refering to the Motorx Guys
I just finished, well cleaned up my fathers old GMF 6" handy Grinder 1/4 HP & 2850rpm. It had all the paint cracking and flaking off. The two sides found to be Alloy

so they are staying alloy and may bling them furthr later. Wife wheel and gringing stone on the rite and polishing cloth with out the cover on the left

Can I put a 8" cloth rather than a 6"
Cheers
