There have been several posts from people turning mesquite. A lot of the mesquite has borer holes in it. I turned a bowl today (pictures after the finish is applied) and there were several through and through holes in the bowl and lots of borer tracks in the sap wood. I pulled a couple of live ones out before turning, as I could see a pile of sawdust coming from a couple of holes. I got the bowl completely finished turning and was sanding the bottom of the bowl. When I stopped the lathe and blew out the dust, there were two more holes in the bowl than were there when I started sanding! I thought you might like to see how we turn mesquite Texas style! It was easy an inch long!
