Now that I received the tail vises for my workbench, I have modeled them in Sketchup so that I can play around with it for a more precise location and drilling plans before I have to physically deal with the heavy top material.
This model is design to be light and fast, and as such does not go into vast details such as screw spirals etc. Instead it is designed to be used for measurements and sizing, both in terms of the actual hardware measurements and shapes, and screw hole locations.
Feel free to download and use this in your upcoming Sketchup projects and designs.
