I took some time today to get into a chunk of oak log that I was given a year or two ago and to my surprise... all of the sapwood had spalted!
Now, my idea is to get 2-3 natural edge bowls out of these blanks so that they have a ring of spalt around the tops. How big does a blank need to be to get some use out of coring?
I did do a search and see some of the differences between a Oneway and A McNaughton... but nothing seemed to address the blanksize.
Any advice?
