Workmate portable workbenches can hold almost anything. But they have a hard time holding on to a short, overhanging piece of 1x2 or 1x4.

Try this: Drill an extra pair of holes, one in each Workmate jaw. Locate the new holes (C) in relation to existing holes A and B, where shown. Insert the standard Workmate dogs into holes A and C to take firm hold of stock that's short and narrow.
