[ATM] grinding outdoors
My mother and father both say that I can't do any grinding even though it
> is fine grinding and polishing in side the house. But I can see the need
> to have it inside because I'm at 320 grit and my telescope mirror is a 20"
> f5, the saggita is at 1/4". And when I grind out doors I sometimes hear
> the grinding of a bit of sand.
>
> Can any of you help me with your support to argue that I should grind
> indoors? Thank you.
