I could use some help. I got an old bandsaw from a neighbor and set it up this weekend. I followed a couple youtube videos on how to tune it, so I think I have the guides/thrust bearing/blade position on tire all correct.

But for some reason, when I try to cut anything resembling a curve, the blade just twists as I twist the wood, and refuses to cut anything more than a very very very slight curve. 1/4” blade.

I have a piece for a toolbox i’m building that has some relatively tight curves that I want to cut, and ideally I’d like to use the bandsaw to get them cut as close as possible.

Here are pictures of how I have everything set up: http://imgur.com/a/KYYBw

Can anyone offer advice or help on how to fix this?

it’s the blade that was on it – it doesn’t look like it’s in terrible shape, though it does seem to have a bit of trouble cutting.

Then I would think it is the blade, they are not that expensive, I would get a new one.

Ok thanks, I will definitely try that. Are the blades at big box stores decent quality? Or should I shop online for a much better blade?

I would check the tension as well. Might not be tight enough.

+1 on the tension.

The rule of thumb I use is I set the guide at 6”
and press the blade sideways with three
fingers… the fingertips should go white
with only about 1/4” of deflection.

Thanks – I think the tension is ok. There’s very little play in the blade when putting pressure on it from the side. But I will check again tonight to see if I should adjust it.
