Converting A Bench Grinder To A Metal Polisher

I was very lucky to acquire a 3/4 HP bench grinder from my Uncle & his father in law, which will help me immensely to polish up a lot of the metal parts on my turntable restorations.
First things first, doing the conversion! Warning, it's my first time.
EDIT // I use "two" spanners, not "to" haha! Hopefully you knew what I meant.

I bought those same spindles from supercheap and they dont fit on my grinder either - thanks for the advice

You're welcome! I thought a few people might have encountered the same problem.

So the logic is you had to buy this special screw piece because the polishing wheel is so thick and if you had a thin buffing wheel you could just use washers and a nut? Cuse my doubts just want to attach this polishing wheels

So why are they selling this crap if it’s not a straight fit!
