Hi guys,
   Well, there are some people in this Universe who are blessed with the talent of not being able to do anything mechanical -- I'm one of those. My fear of cross threading the CW shaft into the CW adapter has finally come true :( :

As I untwisted the shaft out of the adapter (cursing and swearing + tapping with mallet on a long hex driver inserted into a hole in the adapter), instead of the shaft coming off, the metal sleeve came off with the shaft :(

Any ideas about how I can remove the shaft from the adapter?

And the best part was that I had actually lubed the threads of CW shaft so that I wouldn't do this.



P.S. The good thing is that I still have the old version of the CW adapter and an extra CW shaft, so technically, the AP1100 is still fine.
