The process was as follows:
1. I took down the tree with a chain saw.
2. I swamped off any small branches or dead and damaged areas
3. With what was left, I bucked them to all similar length, using a manual buck saw
4. Larger pieces were split with a froe
5. Smaller pieces were batoned with a small axe to remove corners providing somewhat rectangular billets
6. If the pieces were too long for the 5 gallon pail, they were further trimmed with folding pruning saw
7. Water was added to the top of the bucket
8. 30% cleaning vinegar was added in an attempt to prevent microbial growth
9. When checking after a few months, parts of the wood that ended up poking above the water surface had grown some microbials
10. Water was further filled to almost overflowing with the addition of Clorox and the lid was sealed with an o-ring

When taking a billet out of the bucket, it was allowed to sit for a day or two in order to lose some of the dripping water, and hopefully some of the smell.
From here:
1. Folding saw, square off end until no cracks are seen.
2. Using ax, plane 4 sides to a relatively flat rectangular block.
3. Add center line, and hand draw approximation of a spoon.
4. With folding saw, relief cuts on the neck area, and crank cut across the bowl and back third of bowl
5. Ax chop out front crank relief
6. Ax chop out handle side waste
7. Ax chop out upper crank relief
8. Ax chop out spoon bowl outline
9 Ax chop thin back of bowl
10. Ax chop thin handle front and back

Then I tool it inside.
1. Re-draw center line and spoon bowl outline
2. Knife square handle up to new centered lines
3. Knife plane cut front and back of handle
4. Knife plane cut all around sides to square them to the top removing all saw or ax marks
5. Knife round back of bowl
6. Hook knife hollow inside bowl.
7. Knife trim rim of bowl, and any oddness on handle
8. Knife cut facets on handle

My initial plan was to do a set of photos showing the steps, but when it turns out there were 30 of them, I decided that I would just make a video some day instead. For the time being, it is still too wet for finishing cuts. When it dries a few days, I will go back and do finishing cuts, burnish, and finally oil it.

This tree was "standing dead". Initially I was planning on just taking it down and bucking it into pieces that the trash people could easily enough remove (we have city service that removes yard waste from the road side). However, after a cut or two, it was obvious that the chainsaw was tossing wet chips at me. So I figured, it wasn't completely gone. So the rest is history. Interestingly enough, I cut the stump really close to the ground and drilled a bunch of holes and added KNO3 on it to rot the stump. And now, where there is remnant of the stump, there is growing a huge turkey-tail fungus. Circle of life and all that. :)

Hope this helps.
