Abstract
A dipper handle includes a dipper tube, a dipper engagement member, and an intermediate member between the dipper tube and the dipper engagement member. The dipper tube has a substantially cylindrical outer surface and a contoured inner surface. The contoured inner surface results in multiple wall thicknesses for the dipper tube, including a first thickness proximate a first end and a second, larger thickness, proximate a second end. The second end is configured for coupling to the intermediate member.
