I am planning to use wood bindings .250" tall by .080" to .082" wide, and BWB purflings .093" tall by .058" to .060" wide. I will use the purflings on the top, back and sides. I have the LMI set of router bearings, but don't know which to use with my router/binding jig. Any suggestions? Also, should the purflings on the top and back be glued in separately, or all at once with the bindings? Thanks, Ray |

Ray, some people glue them in all at once, but that's too much for me. I like gluing the purflings in first with CA glue. Just be sure to seal the edge of the top with shellac so the CA doesn't wick into your top. |

By the way, stewmac makes a nice li'l bottle of medium CA with a brush attached to the top, like nail polish. It has worked great for me. |

Michael, Doesen't the Titebond stick to the PVC? Thanks, Ray |

So, my question boils down to this: Since the LMI bearings provide purfling ledges in increments of .010", and my purfling widths are between increments - shall I choose the bearing set that "forces" the purfling, or the set that allows for a gap? Can I expect that the purflings will swell to fit the overly wide ledge? Thanks, Ray |

You should be able to get the depth of the ledge closer to the width of the purfling by wrapping a layer of tape around the bearing. You want purfling to fit tight between the top and the binding. The purfling might swell a little from the moisture in the glue, but you don't want to depend on that to fill a gap. |

In that situation I sand my bindings to match the rabbet. If you use one that is slightly too small and sand your bindings a little more you should get a perfect fit. |

Ray, I add about .010 to conpensate for swelling of the bindings and purflings... if using wood glue. |
