You deserve some good answers. Unfortunately, I don't think you will find them here. Look at the member statistics. If you filter out the members who have not posted ten times or more, you can count the remainder on your fingers. If you do not include Jeff, the moderator, who is very knowledgeable, I come in about fourth. I am not a professional sharpener. Ionut, who is the most active participant, has stated he is an amateur. I'm not sure about Herman or Ern.
I would assume there are some professionals in the membership, and probably a larger numbers of sideline sharpeners. The bulk of the membership, unfortunately, is mute. That seems regrettable, because I believe we may have much more expertise in the group.
I would suggest you check out sharpeningmadeeasy.com. Steve Buttorff seems a very experiences sharpener who uses (several) Tormek machines.
I hope the non posting members will prove me wrong and chime in.
