A wall panel jack comprising a turnbuckle connecting a cradle shaft to a foot shaft, a cradle pivotably attached to an extreme of the cradle shaft opposite the turnbuckle, and a foot pivotably attached to an extreme of the foot shaft opposite the turnbuckle. The turnbuckle incorporates a turnbuckle bore with a turnbuckle bore cradle thread and a turnbuckle bore foot thread. The cradle shaft has a cradle shaft thread sized to mate with the turnbuckle bore cradle thread, and the foot shaft has a foot shaft thread sized to mate with the turnbuckle bore foot thread. The cradle incorporates a cradle groove sized to admit the lower edge of a wall panel, and the foot incorporates a foot pad made of non-slip material. Rotation of the turnbuckle varies the distance between the cradle groove and the foot pad. The method includes the steps of placing a suction cup handle in the cradle groove; positioning the wall panel jack vertically, the cradle topmost, with the foot on a floor and the suction cup against the wall panel; moving the foot away from the wall until the wall panel jack is disposed at an angle of 5-10 degrees relative to the wall; attaching the suction cup to the wall panel; lifting the wall panel into a position slightly higher than its intended installed height by rotating the turnbuckle; placing blocks on the floor under the wall panel; lowering the wall panel onto the blocks by rotating the turnbuckle; and fastening the wall panel to the wall.
A wall panel jack comprising a turnbuckle connecting a cradle shaft to a foot shafts, a cradle comprising a cradle groove pivotably attached to an extreme of said cradle shaft opposite said turnbuckle, and a foot pivotably attached to an extreme of said foot shaft opposite said turnbuckle, said turnbuckle comprising a turnbuckle bore, a turnbuckle bore cradle thread disposed on an upper part of said turnbuckle bore, a turnbuckle bore foot thread disposed on a lower part of said turnbuckle bore, a sense of rotation of said turnbuckle bore cradle thread being opposite a sense of rotation of said turnbuckle bore foot thread, a cradle shaft thread on said cradle shaft sized to mate with said turnbuckle bore cradle thread, and a foot thread on said foot shaft sized to mate with said turnbuckle bore foot thread, said cradle further comprising a cradle aperture, a pivot range of said cradle shaft relative to said cradle being bounded by walls of said cradle aperture, said cradle shaft pivot range extending to .+-.5 degrees from perpendicular relative to said cradle groove.
