Thread: bandsaw being a total b#$%%

Have you got your guides set properly.

Is the blade running in the centre of the wheels.

Do you have enought tension on the blade.

Is it the only blade you have, does the machine work better with one of the old blades, if so you have got a dud blade perahaps..

You can get this if the blade has cracked or is kinked.

Try turning it by hand to identify when and where the noise is ocurring.

Sounds like a tooth or two on the blade is way out of whack.

I'd disconnect the power and do as WB suggests. Just turn it over in the normal direction while closely watching the blade as it runs past the guides. Whatever is causing the problem should be very obvious.

Toni,

are you cutting straight, or gentle curves, or tight curves?

Does it happen on different types of wood?

Does it happen as soon as you start cutting, or only after you've used the saw for a while?

Are you cutting wood laying flat on the table, or are you cutting round sections of wood?

Cheers,
Andrew

Hi Andrew, does not matter straight, curved, what kind of wood. it does not matter how long I been cutting it usually within the first 2" and she will grab and it square pieces flat on the table still grabs. I am so close to never using it today. I even contemplated just going to buy a new baby gmc bandsaw because it did all that I asked of it

Did you post a thread earlier on this machine, re setting up of blade drive wheels?

no I don't think so.

I'm sorry I don't understand this talk of a bandsaw going "bang"!

What bandsaw are you using, what are you using it for?

When you say "within the first 2 inches and she will grab and it square pieces flat on the table still grabs" sorry I don't understand?

Many questions, but we are here to help!

Good Health

Hmmm...

the only time my bandsaw has gone "bang" was when cutting a curved branch, and as it fed through the cutting point lifted off the table, and the saw promptly whacked the branch back down onto the table.
Hence my question about round vs. flat.

I've only had one "grab" and that was cutting green timber. As I cut through a knot, the blade started squealing, steam came out of the cut, then the blade stopped but the motor kept trying.
The wood clamped onto the blade so hard it kinked it.

In your case, given that it happens with various woods implies it's either the saw, or the blade.

I'm wondering if your table is warped, or your insert is not bedded properly.
So once the wood gets past the 'pivot point', the blade slaps it down onto the table. The angle of the wood changes, and it can grab. (See pics for what I'm thinking).

If not this, then can you swap to a different blade?

Cheers,
Andrew

Hi Tony it literally makes a bang sound literally goes clunk and then grabs that wood like no tommorrow. The wood is flat on the table. It jams the blade when it happens which caused the wood to get damaged

Perhaps you are right. I will get hubby to have a look at it for me
Toni

it sounds like a kinked or bent blade

Or the lower blade guides way out together with a kink on the blade as well.

Check where the blade is welded. Does the blade protrude at the back or front? Hold a pencil to the back of the blade while running, can you feel a ticking?

Do the teeth point in the same direction at the weld instead of alternating?

Check the blade is seated properly on the rear bearing and not rolling off.

Check there is sufficient tension on the blade.

Where did you get the blade, how many tpi is it?

EDIT: This post assumes you checked the blade isn't bent or kinked (as Bob said) that would be my first suspicion, particularly if the saw worked up until that blade was fitted.
