6 inch or 8 inch bench grinder for moto workshop? Would like to use wire brush, grinding wheels for sharpening along with adding spindles and having the option for buffing/polishing. Which one would be best for polishing? Have read that 8 inch is more powerful but slower? Is 8 inch overkill for home workshop?
i have 2 8 inch older grinders and a new 6 inch chinese knock off. the 8 inch aus grinders i use. the 6 inch chinese crap is in a corner on the floor and my honest opinion of it is that i wasted my money.hope you understand what i am saying. buy the biggest and not chinese.
Yep, go 8” and a good quality 2nd hand one will most likely be better than a new one built from Chinesium. This is especially so if you are going to use high load applications like polishing and wire brushing. If you ave the room, put one on a stand so you have plenty of clearance around it. Makes it easier to clean up afterwards as well. Sent from my iPhone using Tapatalk Pro
Agree with what was said above. Making a very sturdy portable stand with huge clearance as Andy as has mentioned is the way to go. This way , when you start to polish some alloy rim's you can shift the unit into the backyard , right away from everything that you don't want the metal polish over. I bolted my old washing machine motor converted to a polisher on a portable workbench , what a mess i made , black metal polish everywhere , but well worth it , the rim's came up a treat.
if you can find an old aussie brand grinder then grab it, lok on facebook marketplace or gumtree. do not believe any crap from fleabay sellers. if you buy newgo to an honest tool shop and be prepared to pay over 250 for one. forget the 99 dollar suckemin specials.at the same time buy a pair of matching spindles. after that then buy an assortment of polishing wheels and a stainless steel wire wheel.and the pocket will cry out but they will last.
