You shouldn't need much. When I did it, I pretty much filled the gaps, but that is really overkill. The magnets can't climb over the welding, so you only need to create a wedge between them. What kind of JB Weld did you use? There are different kinds, some more suitable to this application than others. Other than that, perhaps the surface was oil-contaminated and the weld did not stick. There are pictures of welded magnets in a thread someplace on this forum. Have a search.
