I cut part of a burl I got this week..Tried my hand at turning it..It has many voids in it and I'm stuck as to what I should do with it next..If I go to 3/4in thickness it's going to have a huge open area.I have used inlaying material in the past but I think this is too big of a fill in job..I do have some acrylic 2 part gel that I could use to fill but have never done it before..As far as the black on the insides of all the voids and craters in it..Is it best to wash them out somehow?Maybe pressure wash or something??Hopefully the pics will help explain the problem..
