Sometime in the past I acquired this vise but never used it. The only identification is “Hawthorne Vise” cast into the smaller aluminum wedge. Googling that name produced no results.
At first, using it seems obvious and I have seen other versions of this type vise before. In using it you would mount the larger aluminum piece to something stable using two screws, place the smaller wedge on it, and jam your work piece between the two pieces. It will hold the work piece tight as long as your work forces are directed toward its smaller end.
Looking at the underside of the smaller wedge you can see another screw hole and also two half-circle cutouts cast in one of the rail channels. These are all cast into it and are there for some purpose unknown to me.
The overall lengths are 5-7/8” for the larger piece and 3-3/8” for the smaller one.. It could hold wood 2” wide (maybe a little more) down to veneer thickness.
Any knowledge or thoughts on this will be appreciated.
