Great thread.

One thing I use for getting those hard to reach corners near the handle is pieces of grinding belts cut to the size of a 25cent piece (or smaller if needed) and used in the dremel. You just poke a hole with your SS4 in the middle and use the dremmel bit with the screw in the end. I use a LOT of these as a 80 grit disk can remove material and metal and 600 grit will polish. You can even use regular sandpaper if you have a belt disk as backing.
