better bandsaw cuts
Is there a trick to making more accurate bandsaw cuts? Try as I might,
when I cut pieces out there is small ups and downs along the cut line. I try to go slow and stay on the line or along one edge of it but stil end up with some hills and valleys. My bandsaw blade is quite thin, may 1/4", do you suppose going to a thicker blade would help? Thank you. II |

Has the saw been set up properly to track straight? Are the guides set right? Bearings? Are you cutting freehand or using a fence? |

You also need to adjust your fence for blade drift. |

My bandsaw blade is quite thin, may 1/4", do you suppose going to a thicker blade would help? Certainly a wider blade is for straight cuts, and a 1/4" is fairly thin. Or it could just be the bandsaw... I used to borrow a friends when I needed a bandsaw and could never cut anything straight, or accurately follow a curve. I figured bandsaws were over rated. Then I bought my own. It cuts straight when I want it to, and follows curves pretty easily. YMMV Check your blade tension first. If it's not set for your type blade i. e. 1/2, 3/8", etc. your cuts will be crappy. |

Bandsaw is not meant to be a precision machine, but some consderations
may help: Smooth weld on the blade, no kinks, go SLOWER, go EVEN SLOWER, keep bearing close to the job. Use spindle sander after. LOL |

Well, I have to admit that the saw does vibrate ALOT and that I haven't
checked the guides for lateral movement in some time. I think there may be something to comment about it being partly the saw too. This bandsaw is really cheap model from Sears and leaves much to be desired! I will take a look at all the things you guys have mentioned.........you are a great help, thank you! II |

It sounds like you could use some help to take you to the next level. I am outside Seattle and would be happy to give you a hand. |

And by precise I am comparing to my TS that typically leaves no tooth marks. |

I read 'blade drift' to mean the blade was not cutting where it was
pointed at. This can be caused by a crooked or bent bade, a blade with too much pressure on the rear bearing, too little blade tension, or the workpiece is not flat or warped, the cut closes as it is cut, any number of things besides the fence. If you cannot hold the piece against and follow the fence, t is not a blade problem |

I never said you cannot do some nice work on a bandsaw. We also use
smaller ones, but as has been related here, everyhing must be pretty shipshpe to get a nice finish, and it will never be as nice as a planed or scraped surface, nor was it ever intended to be. |

I tightened up the guides and I also increased the tension on the blade. These small adjustments made a BIG difference in the cuts. I will buy a deeper blade tomorrow and see if additional improvements can be made. Thank you for the help guys! II |

If by "deeper" you mean wider and you want a wonderful blade for resawing, get a Wood Slicer blade from Highland Hardware - *much* better than the Timber Wolf blades. http://www.tools-for-woodworking.com/index.asp -- dadiOH ____________________________ dadiOH's dandies v3.06... ....a help file of info about MP3s, recording from LP/cassette and tips & tricks on this and that.

I've also just read that another cause is because only one side of the
blade (the inside) is against the wheels. The outside of the blade never rubs against anything - that can make the inward set teeth wear differently from the outward set teeth.
