I'm not keen on epoxies in general accept for very specific work, usually of a very modern nature.
I use it in the design and building of aquarium and vivarium, but never really in furniture work at all. Frankly I don't use any modern "plastics" for such work because it simply can't develop a traditional patina as we find in all our loved and coveted antiques.
In your case, if you do have some seriously soft punky wood, there are a number of wood solidifies designed specifically for this. Abatron
makes some, but I prefer a more sustainable and plant based product for such work. Ecopoxy
for...just those soft areas...that need to be solidified, then I sand/plane the surface back to natural bare wood.
For achieving a long term (centuries or longer) finish that is capable of developing a traditional rich patina. I use a blend from Heritage Finishes
...The grain of such wood will have a depth of color and grain that you really can not achieve with modern plastic finishes...
Good Luck!!! That's a beautiful piece of wood!!!
