Thanks guys.  It was a fun challenge but I am glad it is done.   I actually started this back in December, though I had a couple of month's break in there too.   I learned a lot and I identified some changes should I ever get drafted into making another one.  

Duck, I never did fill the gap  between the external sleeve and the bell that you saw when you were here.  I may get a strip of leather just to hide the gap but it is just cosmetic and it feels pretty strong  with the internal sleeve in place after I filled the gap shown above with epoxy putty.  I've already changed my design in CAD to make the joint simpler and stronger should I ever make another one.
