I wish I could claim credit for this but I saw it in the current issue of Progressive Farmer mag. Get a socket that will fit your drain plug, in the case of our Cummins we could use a F 1/2 drive to a M 3/8 drive adapter. Weld it on to a 1" by 1/8" flat bar with the 3/8 drive pointing straight up. Bend the ends of the flat bar to fit the inside slope of a funnel and bolt it in place. Use your normal 3/8 drive to loosen the oil drain plug and then use the funnel, flat bar, socket combination to finish removing the plug. When the plug comes out the socket will hold the plug and the funnel will catch the oil. No oil on your hands or the floor and the plug will be held and not dropped into the catch pan. Sounds like a good idea to me.
