Topic tags/keywords: planner grizzly tear out i know this question has been asked around a lot. Heck Ive mustve read like 30 articles going over the issue, but Ive checked all the boxes and the tear out Im getting is slightly different. I am not just getting it here and there on the board it is all over it. I bought this grizzly 15” 1021Z from CL, and have gone through the setup process to make sure all is calibrated and up to specs. (new knives, adjusted chip breaker, adjusted infeed and outfeed rollers) and still getting tear out no matter which way i put it though, and any species of wood. Here are some pics of this dreaded wood eater: Ive also done small and big depths taken out and still same problem. Any Ideas on what I could do to eliminate this? |

Pass a sander or hand plane over it and see if it’s minor. I wouldn’t worry about it if it isn’t bad because I wouldn’t finish anything straight off the machine. -- Shooting down the walls of heartache. Bang bang. I am. The warrior. |

I mean I could try to do that, however, the planner isnt effectively doing its job. I also have a dewalt 734 and that planes boards like glass, so I think I should be able to fix this without having to do any sanding…right? |

That looks like chips getting between the cutter and the wood. Need to improve your dust collection on the machine, make sure it’s not clogged. |

That’s my conclusion as well. Do you have DC hooked up to it? Given that it happens with everything, it becomes even more suspect. -- Our village hasn't lost it's idiot, he was elected to congress. |

I have a 2HP 70 Gal DC hooked up to it. Could it be that chip breaker isnt doing its job. A little more information, as feed the board into the planer the board jerks up about a quarter to 3/8s an inch then goes flat again. I cant seem to pin point why it does that because the infeed roller is only set .04 of a inch below the knives and shouldnt pull the board down at all. |

Infeed and out feed should be just a hair high to prevent snipe, and the board will not jump at all. Look for a clog inside the machine, sounds like you have a good DC. |

As to the jerking thing, something is definitely wrong there. I can’t think of why it would do that other than a bedroller too high. It must not be contacting the cutters because you’d be getting a bad snipe on the infeed side (??) Also, that doesn’t look like typical tear out to me. I agree it looks like shavings are burnishing the wood. I would run it past Grizzly their tech support is fairly good. -- Everything is a prototype thats why its one of a kind!! |

The Grizzly manual says to have the infeed and outfeed rollers at .040” below the knives not above like you are saying. Unless I read the manual wrong. |

I don’t know Grizzly, I have a Ridgid that I bought new in 2000, it has infeed and outfeed tables and they must be just a little higher than level with the feed rollers and I have no snipe, jumping. Every now and then I get a little of what you call tearout and I just remove the dust shoot and blow out the machine with air to correct the problem. |

oh you meant infeed and outfeed tables not rollers. :) bit confused there for a second. I also checked dust shroud and didnt see/feel anything. |
#12 posted 12-20-2016 12:16 PM |
so I went ahead confirmed all my measurements of roller height from knives, chip breaker, chip deflector, bed rollers…etc and all seem correct, however, I am still getting strange tear out and that jerk i get from feeding it in. I have added a video of the jerk im talking about and will get on the phone with Grizzly today to ask about the tear out. Heres the link: As you can see from video when i feed the board in I get a jump of about an 1” or more on when the board enters the infeed roller. |

Check the board for snipe. I’ve had that happen to me, too on shorter lengths of wood. -- Everything is a prototype thats why its one of a kind!! |
#14 posted 12-20-2016 04:00 PM |
no snipe which is another funny thing. plus on second pass of board on video it does the same thing with no adjustment to the depth of cut. I just get what looks like knife/infeed roller impressions in the wood like the following picture, which i think is because of the depth of cut being too small: |
#15 posted 12-21-2016 01:39 AM |
That really looks like too much down pressure on the infeed roller. In addition to roller height there should be a roller pressure adjustment. Check the manual on that, There is on my Grizzly which is about the same thing as a Shop Fox. -- Everything is a prototype thats why its one of a kind!! |
