Here a bowl I made a week or so ago. It is spalted hackberry and was way too punky to get a smooth cut. I used my Epoxy Manhatten method and here is the result:
For those who don't know, the epoxy manhatten (aptly named by Bill Stevener!) is System Three epoxy thinned with DNA to the consistency of real maple syrup. You turn your piece to a little thicker than you want and then apply this until the wood will not take anymore. Let it sit 48 hours to cure and then finish turning. The really punky areas will soak up more epoxy and give a visual contrast, as in this case. The white areas are good solid wood that did not drink any up.
I gave the bowl away but IIRC, it is around 5" diameter and 5" tall with wall thickness of 3/8 or so. The epoxy completely penetrated 100% on the punky areas. I know the form is not anything exciting but i was really just experimenting with the wood. The wood was soo punky you could stick an awl 1 1/2" deep into the blank in some areas!
