Frustrated, to say the least. Started with a piece of cherry to make a lidded box which became a design modification ending up as a practice piece. I have the Wolverine system and Vari-Grind and Rikon grinder. I tried to grind a Benjamin's Best bowl gouge to an Irish grind; off a video. Worked decent but when I got the the middle, I got brown rings in the wood and couldn't remove the little nub in the center. Played around with different angles and even tried to go back to the original grind. Not good. I have always valued the opinions/expertise/experience of the members. Your help is most appreciated. Have a project to take to the chapter meeting next week but want to go beyond a pen and pencil set or a beehive which I have done in the past...if possible.
