A sanding stick for beveled edges. It serves for evening out and smoothing a bevel after a cut and for sanding down a sprue nub after a part has been taken off the frame.
Responsibility details are not available.
Working a bevel is among the places where sanding by hand goes wrong fastest. Abrasive on a finger takes an edge down more in one place and less in another, and the resulting surface waves. A sanding stick intended precisely for beveled edges holds the working face in a constant position, so a bevel comes out the same along its whole length and does not get rounded.
The commonest situation is the trace left after a part has been nipped off the frame. The remains of the nub have to be evened out level with the edge, but not sanded past it, otherwise a hollow arises at the joint. The second situation is a deliberate bevel: modelers use it to bring out the edges of armor plates, the panels of robots or parts cut from sheet, because a sharp edge with a fine bevel catches the light and a model looks tighter once varnished.
Work dry and in short strokes in one direction, turning the part against the light between strokes to check the width of the bevel. Take the material off a little at a time; it can always be sanded further, but what has been taken off cannot be put back. Tap the dust off as you go, otherwise clogged grit starts to skid over the plastic and polishes the surface rather than sanding it. Before varnishing, go over the edge once more with the finest grit, so that the paint does not bring out scratches on it.
A bevel pays off most on edges which on a finished model lie against the light. It is precisely there that a sharp line decides the impression of the whole surface.
