Jonathan,
I still have the tubular sleeve that came with the nut so I can use that. It is a double nut so I am going to split it and try to do each half seperately. Hopefully this will be alot easier. I am going to get some light grease tomorrow as well so that I can use it to "glue" the balls in place. I can always wash it out again when the nut is assembled. I didnt know that some nuts had different size balls. I need to check that as well.

Ian
