...I hope. Here's the frame I built for lifting DB-15 contactors into place. The sheet metal cover of the box will be under the upper rails, and the lower rails will rest on a 4x8 sheet of plywood, which I can raise and level with scrap lumber. It's not quite done: I want to install carriage bolts in the tension stiles, and I can get those at the car shop. We've got lots.
The contactor itself is not designed to stand upright on a flat surface, so a piece of plywood with wooden strips is needed to keep it vertical, and also keep it from falling off. The jack I just took out of my car. I haven't had to change a tire for at least 20 years, so let's hope I don't have a flat in the next month or so!
