Angle sander? Angulator?
I saw a thing like this online, and decided to make my own. I reckon some of y'all need one as well, and so here you go - now you can have one for free. Note: It's easier to just use double-sided tape to fasten the sandpaper than to use the little squeezy bits. If the pin is too small or too big, just scale it. The screw is a 4mm machine screw, and you'll need a matching nut underneath.
