I forgot about this thread. The original socket I modified in the pictures turned out to not be quite deep enough so I had to go out and get a deeper ($$$) one. I'll post pictures one of these days...if I ever get back home. The concept is still the same though.
How deep is the final working socket (i.e. what would be the overall height of the socket)? Was your second socket still 1 1/4" or 32 mm? How deep (high) do the 'teeth' need to be?
I'm trying to construct something without ever having seen an original or even the castle nut, so that when mine finally comes apart, I'll hopefully be all ready to go.
Thank for any additional info.
