I have been agonizing over this upcoming bench build for months now. I thought I had ti finalized, planning a leg vise as the face vise, a wagon vise as one end vise and a twin-screw as the other end vise.
I really am set on the leg vise because this bench will be very short and the twin-screw will take up too much of the front edge. I am also really set on the twin-screw for end-grain tasks.
I had planned on putting the wagon vise on the right side (with the leg vise on the left) in traditional fashion and adding the twin-screw to the left of the leg vise as sort of an extra. I have always loved the elegance of the wagon vise and how it is all contained below the bench top. I also like the idea of not having to extend a vise over the edge of the bench when it might not be clamped completely tight since my current end vise sags a little bit when it gets extended two-three inches. This is why I wanted the wagon vise. I admit it is also because I can re-purpose the end vise hardware I currently have.
Am I missing the boat completely? Is there any reason not to eliminate the wagon vise and move the twin-screw to the right end of the bench?
