Seven months ago Jameel Abraham of Benchcrafted sent me a prototype of a shorter version of their Crisscross to see if it could work on the Moravian workbench. I retrofitted it to a bench I had; built to the dimensions given in the video and article. It fit well without any alteration to the structure of the bench. I did have to replace the chop with a thicker one and the back vise mounting piece.
In the time that I have been using it I have fell in love with it!
The Crisscross on this bench is installed with the Classic Vise screw that is also available from Benchcrafted.
This thing has the smoothest operation of any leg vise I have ever used, slick as snot on a doorknob! The holding power is as good as the wooden screws I use. In the configuration I have here the vise opens 9 1/2″ and has 6″ depth between the bench top and the top of the screw.
I have another Moravian bench to finish that will be getting a Crisscross set up. I will do another post in the next week or so detailing the installation. Stay tuned!
