Just wondering about the pros and cons of Hesh's system here. I've seen mention before of keeping the upper transverse brace flat in bracing the top, and I've seen sanding a flat on the top to give a good mating surface for the fb overhang, but this is the first I've seen anyone sand the rims flat in the upper bout. It looks like a good system to me, but wanted to hear some thoughts. Is this one of those "luthier secrets" finally revealed?  And what is the downside? Thanks, Joe |

Joe...there's nothing secret about this and the method has been used for a long time. Check out John Hall's You Tube videos. They're the best on the planet IMO. I've been using John's method for years where he adheres sandpaper to the flat of his radius dishes and sands in the flat. He also has a hole drilled in the center of his dishes and rotates them around a pipe nipple. I don't want to oversimplify his method so be sure to check out his 3 or 4 videos that deal with side geometry. Here's a link to the 1st in the series http://www.youtube.com/watch?v=JFNy93PM0Kc The part on sanding out the upper bout may be in the 3rd or 4th part of the series but it's worth it to view them all. |

Wow, I had no idea this was even a method being used. Thanks for the links. This is why I love the OLF! ![[:Y:]](./images/smilies/smiley20.gif "Thumbs Up")
