Vise stop - video

[Toolmaker51]

Ahhhh, web induced video. Didn't open it to avoid potential nonsense ads, didn't need to open a 25 minute video to digest every element the still discloses.
The old adage that one picture is worth 10,000 words [when often less then 1000 sufficient] proved again.
Besides, that assemblage of 2 clamps and rod dimensions occupies a position too wide and high in the jaw for thin or parts of lower heights. And it only fits correctly on a very limited range of jaw thicknesses.
[on edit] Crusty notes below a table mounted stop is ultimately more universal; absolutely valid. Jaw clamps by nature, suitable only for lightweight parts or careful handling of heavier items.
