So here are a couple of more advanced projects for the novice machinist. The first, a model makers vise, is very handy for doing small work on the workbench. It is all made from cold finished steel (crs).
The second vise is a nice woodworking vice. If you have been looking for a nice aluminum casting project, this might be it. Many years ago when I built my first melting furnace, a drill press vise was one of the first projects I did. This plan is a little more advanced but I would not consider it difficult. The patterns are relatively straight foreword, note the draft lines in the drawing. Draft is generous in the deep section to ease pattern withdrawal from the mold, without damage.
Both of these plans will produce very useful shop accessories that are becoming quite expensive in the retail market, and you will have the satisfaction of having made them yourself.
