by the way,
Amongst all the excellent uses discussed for the LS130 there is still another use that I don't believe I've seen discussed here.
Upon designing and fabricating some of my furniture pieces I'm starting to integrate aluminum and brass into the mix.
One of the uses I find the LS130 very useful for is giving aluminum (or brass) a brushed look, because of its directional capabilities.
I find myself using the Viles pads in its various forms, such as the a100, a280, or s800 grits giving it different brushed looks not so easily achieved by hand using the various scotchbrites available on the market.
