Its just a little larger than the standard deluxe version.
I made this over the weekend out of 1" MDF, it also fits nicely on my Steel City drill press table although the center needs routing before I use it. Used a 5/16" tap to create the screw holes in the mortiser cast iron table and made the stops out of Ipe. The hold down clamps from LV work great, I'll drill more holes for the clamps as necessary.
Thanks Mark Singer and Paul Cresti for the pics and info from previous threads, I'm very happy with your design.
