I am trying to decide how large to make the twin screw chop on my new bench. I am figuring that 18" between screws should be sufficient for the majority of the work I will do, and due to the bench design have other options for those rare occasions when I need to clamp a larger piece. I could go with 24" but feel that the additional size would unnecessarily take up space and be a bit more awkward for general use.
Here is a mock-up. The green tape indicates where the chops will likely be cut. As shown, the chop will accommodate about 20" board, but I think it is a bit too large. The 2x6 in the middle will be an experimental movable jack.

Any suggestions will be appreciated.
