I was wondering the same. Are you talking about what is put into the sand to help it behind and stick better? Or the stuff that he puts on with the bag that looks like flour? Either way, I'd like to know what formula they use for the sand mixture and what is used in that bag to make the sand not stick to the part

That's not a cutting disc. It looks like a lawn mower flywheel.

@@RalphSampson... lol

Yes because that aluminium not 🚫 Iran 🤔 good 👍😊

How is it useless?

@@backwoodsjunkie08 The quality of it is so incredible low. You can literally see that it is hollow on the inside, and the outside surface of it is so misshapen . What use can it have?

​@@backwoodsjunkie08I'm just taking a wild guess here, but I know that when I saw this the other day, my first thought was that a gear, or whatever this is, made out of aluminum wouldn't stand up to very much pressure or wear and tear. On a totally different point, and again, this is just a wild guess, I'd think that working with aluminum this way could be VERY bad for one's health, as far as Alzheimers (and maybe other mental deterioration) goes. Alzheimers has been tied to aluminum exposure and this guy isn't even wearing a useless paper mask, much less one that would really do the job of protecting someone pouring hot liquid aluminum on a daily basis. I could be totally wrong about all of this, but just giving you my ideas anyway. I hope both of us get a valid answer from someone!! Ciao!
