How to sand without sand paper? Answered
So my question is, is there a fairly efficient way to sand something without using sandpaper? I am doing a project for haiti, and i just realized a breakdown in a system. Sandpaper would add a huge cost to anything.
Right to what it is used for: I was wondering, if anyone have any simple ideas on how to sand soda cans after cutting them into sheets? Solutions i can think of in context with whats available in Haiti is may be rubbing the sheets against concrete or even in a sand box?
I am just thinking, back in the old days, before sand paper, how did people do it? any ideas would be really appreciated!
