Bench dogs and the LV Twin Screw Vise
Tony Sade (Charleston, WV)
>I'm in the process of building a bench and plan on using the Lee Valley twin screw vise on one end. I'm going to use square bench dogs in the top and, until I ran into the following brain freeze, was also planning on square bench dogs in the face of the vise.
According to the instructions for the ts vise, the face gets beveled 1/8" to ensure that things square up when force is applied. According to the instructions for the bench dogs, holes get slanted (canted?) 2� in both the top and the vise face. No problem with the holes in the top.
I assume that there's no problem (incompatibility) with the face bevel and slanting the holes in the vise face. What I can't figure out is how to make the slant without getting holes that are wider at the bottom. (I'll be laminating two pieces for the face.)
Slanting the holes in the top of the bench results in holes of uniform thickness top to bottom.(Done on one piece that the gets laminated to the rest of the top.) If I slant the holes in the vise face (doing it the same way as done for the top-in the face of one of the two pieces) won't I get a hole that's deeper at one edge of the face than at the other?
Is the answer to center the hole between the two pieces that get laminated, then raise up one edge the necessary amount? (I'm thinking dado blade here-maybe the issue goes away if I just mark it and do it entirely by hand.) For the second piece I would just flip the board?
Am I hopelessly confused, or confusing the issue? Thanks, Tony
