A purfling install would actually tie together the schemes of the soundboard and back. I kicked myself after I bent the side purfling without installing the additional purfling.

| Post subject: | installing purflings into sides after bindings R installed? |
I was shopping for bindings with pre-installed purfling a few weeks ago and ended up sending them back and making my own. While I was shopping (I forget where) one of the advertisers mentioned that a builder used their purfling and installed them after the bindings were already installed with a router. I thought to myself "that's an odd way to do it". However, I have a pretty nasty binding gap on a build that I am really happy with so far. If I could pull off a purfling install now that the bindings are already installed it would keep this build on the right track and actually improve the look quite a bit. I'm thinking that he must have modified a Dremel or something similar to ride a very small section along the guitar's curves. Any chance anyone has done this, seen it done or would know how to do it? |

What kind of glue did you use? |

I found it, it's on Allied's site. "John Greven's method is to add this trim after the binding is already on the "box." Using the top as a reference along with a Dremel tool, he routes a channel just under the binding. He uses a small hammer to tap in the laminate or strip as he works his way around the guitar." I have a Dremel and the right bit, I just don't think I have the balls lol. I'd like to see how he modded the Dremel. |

My best guess is that he uses the circle cutter and lets the medal pin ride along the top/back as he routes the slot. Luckily I have a body with enough issues that it's going to be re-topped so I'll give it a go on that before routing off the binding. |

Actually that wasn’t too bad at all and should do the trick perfectly once I figure out how to deal with the waist.   Sent from my iPhone using Tapatalk |

This did the trick for testing. Just need to drill and tap an inset screw into the circle attachment and I’ll be good to go with the fix.  Sent from my iPhone using Tapatalk |

I’m pretty glad I took the time to figure that out and then execute it. What a difference.  Sent from my iPhone using Tapatalk |

Wow, that's pretty cool! My first thought is that it might be difficult to lineup because my upper bout binding on the back ends up shorter then the lower back. But actually, if i did it right I could correct that buy starting closer to the binding side at the tail and finishing up closer to the side side. New username, same Pat Mac |

Looks like you pulled it off. I probably would have routed off the installed binding and re-bound it with the purfling... |

That is absolutely brilliant! When that happens to one of mine, i usually fill the gap with sawdust and glue (if it is a guitar i am keeping) or cuss, route the binding off and re-do (if i am not). |

Nice. Never would have thought of that - might have to do with earlier reference to 'balls'? |

Trevor Gore posted a tip here some time ago regarding installing the binding without gaps. It might be something to think about for your next build. He suggested putting a small bevel in the inside bottom edge of the binding before installing. He said something like installing a binding with a 90 degree corner, into a 90 degree channel doesn't allow much room for error. the bevel will allow for the binding to sit more snugly. I do that to all my bindings now. I don't remember how he did it but I just use a block of wood wrapped with sandpaper. It does seem to help quite a bit. |

I use a small file for wood and a razor blade for plastic to make the bevel. |

Thanks for the tip, I have 4 more guitars to bind on the bench right now. I pre-installed the purfling on the unbent binding already for 3/4 of those though so I'll give that a try on at least 3. I may use this method for the other and make a decision on how I want to accomplish this task moving forward. This was certainly quicker than messing around with clamps and Gorilla Glue, that's for sure. Sent from my iPhone using Tapatalk |

New username, same Pat Mac Since the purfling/binding will be covered by the neck at the head I started at the tail and ended up at the head (neck blocks it from view). To be honest I'm considering using this method moving forward. After having routed those 4 channels and installing the purfling I feel more confident doing it this way than the way I was doing it before. John Greven is on to something! He has certainly forgotten more about luthiery than I've ever known. |

I used a dremel to rout for the purfling after binding and it went very well |

Stew-Mac sells a UHMW filler strip (glues don't stick to the material) that is put in binding channel first, the binding proper being held away from the bottom of the channel by the filler strip. After the binding glue dries, the filler strip is pulled out, leaving a .060" channel to hold purfling of that thickness, or so. I've used it on two guitars to my satisfaction and there was no need for me to cut a channel beneath the binding on the guitar side. If I treat it gently, the filler can be re-used. |

Curious: What is the logic behind waiting until after the soundboard is on the body to cut out the soundhole? I've always done it before bracing the soundboard, and it's an easy task at that point. |

This is what you need. The cutter is available in a bubble card at Hime Depot or “Lowes with the Dremel display. The bushings come out of the wierd hardware trays at a big hardware store. It cuts a slot that fits .040” purfling exactly. |
