I purchased this vise from Amazon since it was pretty cheap. The vise arrived and appeared to be reasonable quality, but the template included in the box was not to scale. I printed this to help with marking the table before drilling and fixing it to my workbench table. I included a PDF scan of the original mounting template for reference. The tabs have a gap where you can mark the center location and outer perimeter directly to the mounting surface before drilling.
The author marked this model as their own original creation.
