The Miter Jack is a fixture that is a combination of a vise and shooting board, and is a tool we produce from time to time. We now are offering full scale engineered drawings for those wishing to make their own. These are copies of hand drawn prints and include all components with full dimensions. There are three D size (24″ x 36″ )sheets, along with a half dozen color photos showing various details of an assembled miter jack. One of the sheets is an assembly with all components labeled and all hardware itemized. We ship the plan kit rolled up in a tube so there are no folds. Price is $60 plus shipping.
Lake Erie Toolworks sells a wood screw and nut block blank with the threaded hole already cut. It is made of hard maple and can be purchased here.
We recommend both of these products, as they are of the highest quality.
