If you're bid for a house comes in second, be sure to make a backup offer. This puts you next in line if the first offer falls through. Be sure to keep in touch with the seller's agent, or have your broker touch base.
A picture-framing vise, or miter clamp, has screw holes on the bottom for attaching to a workbench. But for occasional framing it can get in the way of other benchwork. A solution is to mount it on a wooden base that can be readily clamped and unclamped in your bench vise. The base can be of scrap wood, and made up so that the framing vise will be about chest high for comfortable working.
