sandpaper balls I have some 2" rolls of sandpaper that go on a mandrell and allow you to sand inside angles. they are basically a piece of sandpaper rolled up with glue so that as the outer piece wears away a new piece is revealed. It works great.
They come in all sizes and shapes. I only use them on my die grinder if I use a speed control to slow it down to about 10,000 rpm.
I do have a question on making my own. I want to make some for my dremel. so I want to make up a batch of various grit "rolls". question is what kind of glue will hold them together and not get transferred to the wood? |
