    bandsaw help round 2

    hi all

    ok i am working on a project for mom for mothers day . i set up my bandsaw with an 1/8th blade , readjusted everything to use this small of a blade . my problem is that the blade doesn't stay in between the blade guides (cool blocks) and i can't bring them any further foward . the blade is centered on the tires . any other ideas ?

    thanks in advance for the help

    p.s. oops almost forgot its a 14" jet with a riser block ...

    You can come down over to visit and use mine. Not sure if this is the help you were looking for though.

    Check your blade position on the wheels. Maybe you can adjust it back some.

    I have experienced similar and resorted to making guides from Hard wood and letting them engulf the blade. But wait, you say you can't bring the guides forward? Something isn't right? Most problems are that the guides won't set back far enough and eat the set. Begin again and relieve the bottom guides as well as the top guides, (And especially the thrust bearings) remove them from the picture. Work on the tracking and tension till the blade is to your liking. Next move the thrust bearings into play, both top and bottom. Now the guides... I bet the bottom thrust bearing is keeping the blade ahead of the guides. Often we forget to make criticle adjustments below deck, (I know I have ) Follow basics in setup and that should solve your delima

    Jim:

    Ever since my organic chem professor spent half a class period changing an overhead projector bulb because it wasn't plugged in, I like to try to rule out stupid things.

    Is there any chance one of your thrust bearings got moved too far forward?

    OT, but that reminds me of the time I spent several hours replacing the electronic ignition on a Jeep Wrangler...only to find it was simply out of gas.

    1/8" blade.......3/4" radiused cuts?
    whenever i need to use a blade smaller than 1/4" i`ll completely burry it in the guides......cool blocks will work well for this (they`ll sand back smooth when you`re done) or make sacrificial ones from wood. the thrust bearings are totally removed from the equation.
    the way i set the blocks is to jamb them into the running blade so the teeth cut their own path in the blocks then lock down the blocks.
    sam blasco showed a method tought to him by his grandfather that accomplishes the same thing using euro-style guides but i don`t have the link handy

    hi todd , thats the problem i cant bring the guides foward far enough to burry the blade in them. i cant even hit the edge of the blade . this is only on the top guide , the bottom is fine .

    i appreciate all the replies from everyone. everything else is set right like it should be ....... any other ideas

    Thats what I would try. It doesn't have to be centered.

    That or maybe the guide assembly needs shimming or moving (if possible).
    God grant me the senility to forget the people I never liked anyway,
    the good fortune to run into the ones I do,
    and the eyesight to tell the difference.
