I have a quick question regarding making jointer tables coplanar after installing shelix cutter head from 3 knife cutter head. With the three knife cutter head you could make jointer tables coplanar and adjust the knives for that perfect fit. Do I now have to align tables using shelix cutter head as starting reference? -- The Carpenter Bee is derived from the Ancient Greek word wood-cutter "xylokopos/ξυλοκὀπος" |

No, it can be done but it’s very difficult esp if you don’t have precision straight edges. Good Luck -- Aj |

Putting one in you needed to drop the tables, both in and out feed. I raised both up after it was in, so a straightedge laying on both tables, just touched the cutter where the straightedge went across. Then I dropped the outfeed side about 1/8”, not a lot. I used a piece of fairly flat stock 24” that I had already jointed, and ran it in till it cut maybe 6” onto the outfeed table. Then I just moved the infeed, so it totally supported the portion on it, and it still was just making contact with the outfeed. Got another piece of stock, and ran it across like I would to joint it, and it was fine. One of the small things you don’t want to forget is you took off the fence. Now I just hardly ever tilt a jointer fence, so you have to resquare it to the deck. Either that or I about guarantee you’ll be jointing a bevel on everything. That was at first, then I went back and redid the entire thing, just dropping the outfeed around 1/16. After that I was much happier with the results. -- Think safe, be safe |

Okay so I guess it does not affect safety aspect about raising cutterhead a couple thousand or so if tables are already coplanar. Which mine are not since I did have to drop both tables for removal and installation. -- The Carpenter Bee is derived from the Ancient Greek word wood-cutter "xylokopos/ξυλοκὀπος" |

Let’s be clear on alignment of tables. Almost all jointers have table that will adjust up or down with a hand wheels or lever. -- Aj |

Ok I know exactly what that is. I had one about ten years ago with a helical Head it had six rows of nine total 54 inserts. -- Aj |

Also in the pic it shows place shims here on both sides. Disregard this until you absolutely have to . -- Aj |

I too am installing a shelix cutterhead on my 8” jointer with dovetail ways. I was going to shim the cutterhead to the infeed table to align the cutterhead with the infeed table and then shim the outfeed table to the infeed table to align the two tables. Am I correct in thinking that I don’t want to shim the infeed table because it moves up and down. This makes sense to me to do it this way. What are your thoughts on this? Thank you in advance. -- Russ Mitchell |

I wouldn’t shim the infeed. -- Aj |

sorry for not replying, Aj2, back in 2019 :) Once I reset my infeed/outfeed tables with gib screws and jam nut, the thing came to be 99.9% coplaner by default. Must of had one of the screws too tight or something. -- The Carpenter Bee is derived from the Ancient Greek word wood-cutter "xylokopos/ξυλοκὀπος" |

Excellent Mr Holbs :) sometimes just cleaning out years of dust and gunk is all ones needs to do. If it’s a new jointer and the tables are out of alignment well that’s a drag.:( Good Luck -- Aj |

I’m hoping I have the same result as Mr. Holbs, just planning for the worst case where nothing aligns. I have an 8” Delta model 37-380 and previously I had to shim the outfeed table to get it to align with the infeed table. I sure hope that is all I need to do. -- Russ Mitchell |

It doesn’t take much to throw off the alignment on a newer style dovetail jointer. Esp if it’s used & some handling of the jointer from the ends of the tables will do it. Good Luck -- Aj |
