I cleaned a burmese python skeleton years ago, and put it together... and put it back together... and put it together again.  I don't know how many times I have had to repair and work on this 4 ft long snake; often enough I have blocked it out of my memory, hehe.  Well, the reason for the continual falling a part was that I didn't have a case to protect it with.  I finally found a case that the skeleton would fit in.  After a final bit of repair, I now have the skeleton under glass where it can be safely displayed.
