Not really a (tutorial) per say, but rather a little trick I came up with to glue in the linings and not leave crush marks on them. I like to stack two layers of linings on top each other, this spreads out the clamping pressure and avoids denting the delicate thin outside layer of the reverse kerfing. 
This photo shows the compression marks that are often left when we use clamps that provide sufficient enough clamping pressure. 
Hope this helps! |

This is a good trick and even more so with standard triangular kerfing. Not only does it protect the wood, but it puts extra pressure to the thin edge where gaps are unacceptable. John Slobod showed me this trick years ago. |

I could be wrong .. but those marks look an awful lot like some kind of oil residue coming out of the orange clamp liners ... I used to get the same thing when I used a rubber piece as a caul liner when gluing the backstrap on a headstock - solved that with a simple piece of baking paper in between that and the wood. I just switched from binder clips to watkins clamps and couldnt be happier with the results. |

Tony, you may be right, this was a poor excample because its on the back side of the kerfing. I usualy would get this marking along with a crushing or denting of the surface. By the time it was sanded out there was almost nothing left of the face of the reverse kerfing. Binder clips always stain when I use to use them. |

[QUOTE=TonyKarol] I could be wrong .. but those marks look an awful lot like some kind of oil residue coming out of the orange clamp liners [/QUOTE] Yep....I get that too. It seems to either disappear by itself, or sand off. |
