I’m not familiar with all the different jigs out being used so this one in the pic is new to me. What is going on in in this pic with this router jig is this some sort of thickness jig? |

It looks like a thicknessing jig. I assume that the round black things are suction cups to hold the piece down? |

I wonder if it is used to notch out the center reinforcement strip (not shown in this photo) for back braces or something like that? Dave |

The round black things look like balls or rollers to hold down the plate so it can be thicknessed accurately. |

I’m pretty sure it is a thicknessing jig. The round holes are for some method of pushing the plate down flat against the base, although I’m not sure what method is being used in the photo. I guess very large steel balls would do a good job. It wouldn’t be a center strip routing jig (at least not as shown), because the movement of the router allowed by the jig is perpendicular to the center strip line. |

As Dave said, although there is no center strip reinforcement shown, it might be for routing the slot for the back braces. That was my first thought too. In that case, one would want the jig to allow perpendicular movement. The jig looks interesting, but to me, cutting a slot, or space for the back brace with a router jig seems like a lot of work, as opposed to just using a small razor saw. Tom |

My first thought was it is for bringing down the thickness. It looks a lot like a those slab planing sleds guys use with the router. |

Found it! Thicknessing jig. Also discovered that a right click on the mouse over the photo gives an option to search for google images. https://luth.org/books/american-lutheri ... anthology/ |

It would certainly offer a cheaper alternative to a thickness sander as mentioned in the lead-in to the article. I think I would add a skirt like some CNCs have and a dust port for a vacuum cleaner. |
