Another approach to holding stock for small hand operations, talked about here. The above photo shows the bench dog, extended, to hold the "shelf" board or raiser bar. The bar is held to the bench by the rare earth magnets, which supports the stock along its length while clamped by the left vise.
The above photo shows a second bar, with countersunk holes for screwing the bar to the stock. Holding the stock this way allows a range of angles for shaping the work, unhampered by clamps or vises.
