Veritas Bench Blade
This is essentially a low-profile bench dog with a quick-release sliding jaw for holding work. Dubbed a blade due to its flat design, it projects just 1/4in. above a work surface to permit maximum access to a work piece. Used much like a toggle clamp, it has a thumb-operated eccentric cam lever to control the sliding jaw, so you can quickly secure or release work.
With 1/4in. range of travel, the jaw has limited throw, but applies up to 300 lb of clamping force. Flats on the cam provide secure stops at 1/8in. and 1/4in. of travel. The jaw face has a 5 Degrees inward cant to help hold wood securely. The cam and jaw are cast steel, heat-treated for surface hardness, and the post and wedge-lock mechanism are turned steel.
The patented standard post version is for use in a 3/4" diameter through-hole (or blind holes that are at least 1-7/8" deep). The wedge-lock version is usable at any angle from horizontal to vertical, and anchors firmly in any 3/4" diameter through-hole in material as thin as 5/8" (depending on the strength of the material), or in blind holes that are a minimum of 1-3/8" deep.
