It is common to let the tree soak in a lake of a long period of time before you cut and dry it..

But IMO, when your finished what have you got? Black Walnut!!!, not a wood I would normally use except for collector Win. rifles perhaps..I have seen some pretty nice black walnut over the years but 98% of it was mostly Mo. cork wood raised under too mild of conditions...

IMO European walnut from Turkey, Tajikistan, Russia, is presently todays best wood and inasmuch as its a lot of work making a stock, might as well use the best of wood. Same thing with a gun barrel, use the best, that ain't the place to go cheap..

BTW, you can buy cured Black walnut cheaper than you can raise it! smile You would be better off selling the tree.
