Companies designed spudders to move to a jobsite, drill the hole and move on. I think that goes without saying, regardless of whether they were made by Bucyrus-Erie, Speedstar, Cyclone, Loomis, Ideco or Walker-Neer (yes, all real brands). These were not stationary items. I find how they moved almost as interesting as the design of the rigs themselves.
This column deals with water well rigs, which would include mostly Bucyrus-Erie 20Ws and 22Ws, Speedstar 55s and 71s, and Cyclone 36s and 42s. These were popular rigs in my area, where 250 feet was about the deepest we ever drilled for water. I know of deeper wells in Michigan, but in my area much deeper than 250 feet flirts with saltwater.
