Since I could not afford the time or money to make or buy a cabinetmakers workbench I decided to improve the Grizzly bench (H7724) I already had. I already added a plane stop, so the next thing to add was a leg vice. Since I already had two of these benches in the garage, so I stole the vice hardware off of the second bench to make the leg vice.
I attached a 2x10 to the leg of the workbench. This will acts as the base on which to build out one leg of the bench, so it is big enough for the leg vise. I used the plane stop to plane down stock from the lumberyard so it was flat and without twist. Then I roughed up the leg of the workbench and glued the board to the leg. I used woodscrews to help secure the board to the leg as a backup.
Once the glue had dried I came back and glued another flattened 2x10 to the first. The combination provided a solid foundation for the leg. I planed down the second board so that it was flush to the edge of the table.
