Nick; The stem and it's knee are toast. That cut out was the first thing I noticed. There is no real neck left on the wood.
Scaraborgcraft: Using what they had as in a short tube seems likely, or they only had a short drill

As it happens, I damaged the tube on removal. I turned a piece of ash to drive it out and when it finally came, the threads were compressed, and 1/4" of tube mangled. A new tube was in order, so I could get a bigger one and beef up that log. The deadwood all looks like mahogany. Not great in freshwater, but easier to work than oak.
This is a piece of oak I have. Would it be suitable for any of these pieces? It is 4" thick and pieces are 3" dressed. Would grain run out be a problem? Maybe not for the stern knee as I don't fancy drilling it.
Thanks Lupassonic for you comments. Plenty time to do this and no schedule. I will whittle away............the jug fills one drop at a time
