Binding jig - saw one commercially available (not cheap) where the cut is guided or spaced by an offset bearing mounted on a small plate which rotates on another bearing, which is centered on a straight router bit - where was it? |

I always found these off set bearing to be much less accurate then a bearing on the router , Yes you can get a good result as long as you remember you have to be tangent to the bearing. Any deviation will cause a variation in the bearing channel . If you use these set them up so you over cut the channel a few thou so you can sand the sides to the binding . This helps to give you some control on the variable of the process. When doing a 45 style you don't want to have the channel pinched that will result is binding thickness exposure to vary . Knowing where the variable is in the process is one way to help control it. |

I think the keys to keeping these types of setups working well are to make sure the body is pushed up against the guide bearing at all times, and to take two passes. If the body is not snug against the guide bearing with enough pressure (it only takes a little pressure to do the trick), the cut can be shallow. And a second pass to catch any weirdness from the first pass is easy to do. I like single bearing rabbet bit setups, too. But when you get into wider purflings, the available bearings are not small enough. Very frustrating. |

actually the 19 pc router bit set I sell is compatable with the aliexpress router bits and you can get them as wide a 1 1/4 and you can do easily well past what you need and at 12 bux a bit you can set them up and leave them set up. I use this set up and have all my patterns ready and when the bit gets worn a new one is more affordable so I always use sharp bits |

Thanks, John. I'll check those out on your website. But I have the LuthierTool jig, and it is working well for me, so I think I'll stick with that for a while. |

John - What is the diameter of the smallest bearing in the bearing set you have on your website? Thanks. |

I also use this method / cutter. It has taken some getting use to, but I feel pretty confident with it now. Lots of test cuts is the key for me. That along with making sure the body of the guitar stays parallel with the bench. Sent from my iPhone using Tapatalk |
