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.
