Chuck gives good advice. The tool that I have is a Kingsbridge brand. To use remove the other cup, remove the balls and old lube, insert the long side of the tool into the stuck cup (there's a long enough side that sticks out past the shell's other end so the tool's wrench flats can be grabbed). Then depending which way the cup is threaded I clamp either side of the tool in a bench vice and use my 18" crescent wrench with added leverage from a piece of pipe. When you turn the frame it should produce a self tightening torque on the tool. I have come across only a very few cups that I couldn't remove in 35 years. Those few were ground out.
The tool is very simple and would be easy to produce. I would be happy to photo mine and send a link along.
