trunnion trouble, or, why can't I adjust my tablesaw?
Hi, folks,
Using lots of advice I've found on this group, I set about adjusting my Grizzly contractor tablesaw to correct its extreme blade heel problem--the back of the blade was over to the left at least 1/4 inch more than the front of the blade! I loosened the two back trunnion bolts and whacked, to no avail. I loosened one of the front ones--still no better. I have now loosened all four. The whole assemble is will move around, but it seems to be moving AROUND a point at the front of the blade. In other words, I can push the back of the blade (via the trunnions below) and move the assembly and the blade back and forth--but it's basically pivoting at the front of the blade. Just moving the back doesn't make enough of a correction. I need to move the front one way and the back the other, but the front doesn't seem to want to move. Can anyone offer any advice? Thanks! DS |

DS This sound seems to show that the front trunnion is frozen in place. You could try freeing the bolts by the use of a very long cheater. Sometimes bolts can be freed by heating them with a torch, but you might set the whole place on fire if there is any sawdust around. Sometimes, an impact wrench will loosen an otherwise stuck bolt. Otherwise, you might succeed in getting the bolts out by turning the saw over (to keep things from falling down when you get the bolts loose enough). Jim |

DS Are you sure you got all the bolts? On my new saw, I noticed it had 3 bolts in each trunnion compared to the two on my previous saw. |

trunnion trouble, or, why can't I adjust my tablesaw?
I had the exact same problem with my Grizzly G0444Z saw as you, being 1/4"
off and burning the wood when ripping. I previously posted it in this NG. I had a lot of trouble moving the trunnion. One person on this NG said that he put a large clamp on the back trunnion and brought it in by tightening the clamp. I did this too and was able to bring the blade in. I put a dial guage on the blade and the best I could acheive was it being 2,000th of and inch out. I was informed that was good enough. I been toying with the idea of taking the back trunnion off and elongating the 2 holes so that I could get it dead on. I may call Grizzly and see what they say. One thing you should look at is making sure that your fence is not out of alignment too. Some say the fence should be an 1/8th off in the back and others say it should be dead on. I put mine dead on. Take a look at this site http://www.in-lineindustries.com/saw_pals.html Ive been thinking of getting this item. |

So, when you "put a clamp on the back trunnion," what exactly did you
clamp TO? I'm glad to hear I'm not the only who has had this problem. I've talked to the folks at Grizzly and they've tried to be helpful, but they're giving me the basic troubleshooting tips that are in the manual, and don't seem to apply when the amount off is SO much. (I have ordered a set of PALs--thanks for the tip.) Thanks! ds |

Again,
How are you checking for alignment? If you are checking for alignment parallel with the miter slot, make sure you use the SAME spot on the blade for the front and back measurement. Mark the blade with a sharpie and take a measurement in the front then spin the blade positioning the sharpie spot in the back and remeasure. What are you using to make these measurements? -- Stoutman www.garagewoodworks.com |

Thanks for the suggestions. Because the difference from front to back
is so extreme (more than 1/4 inch), I haven't been very precise in my measurements. I'm trying to just get it in the ballpark before bothering with precision. But to answer your question, I'm measuring with a stick clamped to the miter bar. The stick has a screw in the end. Not the ultimate in precision, I know, but good enough to get a least kinda close, I would hope. ds |

What do you mean by "proper alignment"? I am a little skeptical that his saw was that out of wack before he started screwing with it. How close to "proper alignment" can you get with the stick on a miter gauge technique? 0.1" 0.01??? As little as 0.005" in error can adversely effect the quality of your cuts. Was he using the same spot on the blade for the front and back measurements? If he wasn't, he is introducing even more error onto his "stick on a miter gauge" alignment method technique. -- Stoutman www.garagewoodworks.com |

If he's actually 1/4" out, he should be able to eyeball it. Extending the blade on a try-square and dropping its frame into the miter slot will get him even closer. Once he gets it -that- close, he can start casting about for a way to bring it on home. But if he can't get it straight by eye, then he's got more problems than a TS-Aligner can help him with. I think you know that I'm all in favor of using indicators when appropriate. But until he can get it as close as the try-square --or even the screw on a stick-- will allow, he isn't ready for an indicator. Bill -- http://nmwoodworks.com/cube --- avast!

When you first posted, you said that this just happened. It was suggested
then that you check to be sure that nothing is broken or loose. Have you checked? Alignment problems like this don't just happen. "VeryLargeCorp" wrote in message ups.com...

I got my dial gauge and magnetic mount from Harbor Freight both for $16 on sale. It works just great. It was made in China, but so what , the TS Aligner was probably made there too. I also mounted my gauge on a piece of hard wood that fits in the miter gauge track and by doing this I was able to slide the gauge forward and backward. |

Get the screw close but not touching, and the feeler guage will get you to within .001". |

You can get closer than that with a piece of paper. Always available, were a
feeler gage may not be. "Jim Weisgram" wrote in message ... When you are ready for precision, you can add a feeler guage to the mix. Get the screw close but not touching, and the feeler guage will get you to within .001". |

RayV, you may have hit the nail on the head! I was just starting to
wonder if I needed to loosen something to allow the movement I need. I think that may be the issue. I'll try it out and report back. ds |

get it aligned properly. I sold it and bought a General (Canadian) cabinet saw....what a nice piece of machinery. Dave |

In my opinion, you have to have two things to align
any contractor saw: (1) TS-Aligner ttp://www.ts-aligner.com/ (2) http://www.in-lineindustries.com/saw_pals.html Without these two devices, you are in for a very long day or night....... You also need the instructions I gave you in a earlier message from the B&D site.

Is this a new saw? If so, return it, it's defective. That is assuming
you didn't forget to loosen a bolt or two!! I don't like the idea of using clamps to get a casting to line up. Whats actually moving when you use the clamps? Is something bending? Maybe this is why we hear of broken trunions? Be careful with it. I've seen cast iron pieces snap, when tightened down, and not aligned properly. |

I missed the beginning of this thread, but if it's a contractor saw check to be sure the error is the same at 90 and at 45. If not, the two bars connecting the front and back trunnions are not parallel. -- It's turtles, all the way down |

You don't want to find that out when you crank over to make a bevel cut. In particular, there is a rather small zone that clears the insert. The blade to slot dimension has a small tolerance. Frank |
