Check the blade balance, check the collet and make sure it is tight and on correctly. Check the blade shaft for alignment and check all the bearings.

A defective motor shaft bearing would be the most likely cause if the blade is not bent.

SOURCE: I have an old Sears

I am not real sure about how this saw is put together, I am looking for a breakdown, but in most saws when they get a wobble its the bearing on the spindle shaft. If you still need an answer come to my page phoenixrepair.org and let me know. I will try to find out if that parts are available.

How do i open the motor to a black&decker 71&2 inch band saw ? my saw has started to make a lot more noise when runing


There are many reasons why band saw make noise. Here's are some "few checks" to do
1. Run the band saw without blade.
2. Run with a different blade.
3. Run the motor alone.
4. Check the bearings.
Another thing; incorrect speeds and feeds can cause noise and vibration.
Regarding about opening the motor, I can't help you with that. Try to check any other band saw motor manual reference.

I have Trajan 7x12 band saw, no vibration or noisy at all, I use Haltbar blade from sawblade.com

Bandsaw blades keep popping off,could it be heat related?


Blades slip off the wheels on these saws is because one or both wheels are not turning true to the blade. This can be caused by:
- Missing or worn tires on the wheels. The rubber tires have to be on the wheels and they have to be in good condition.
- Occasionally the screws holding the sprocket on the driven wheel come loose and the wheel will wobble causing the blade to come off.
- Both wheels ride on bearings and shafts that, if seized, worn or broken, will let the wheel wobble enough that the blade won't stay on.
- If the blade is stretched or twisted from use it won't stay on very well.

Vibration when blade on no vibration when blade off


you have a bad blade or the flanges are worn causing a runout of the blade, if you can watch the blade as it slows down you can see the wobble,

Blade does not track properly causes "tires" on drivewheels to come off making blade wobble.


Depending on the make and model of the bandsaw there should be tracking adjustment handwheels to get the bands to run center. If you have already done this, then inspect the drive wheel and the idler for being slightly bent, and or bearing/shaft failure.

HI, I have a Black & Decker 12 amp ''Spitfire'' corded 7 1/4 circular saw. The problem is that the blade wobbles left to right. I can even wobble the blade with my own hands when its not operating,...


There's a cap that slips onto the spindle before you put the anchoring nut on. Make sure it's there but the thing that makes blades wobble alot of times is the other one that's on the backside of the blade. They fall out, unnoticed, and since some folks don't know about the one on the inside of the blade they never realize it's not there. Just a thought.

Blade acts unusual


Hi, Blade wobble at high speed can be very dangerous! The saw at the right ( wrong) wobble can destroy itself.There are a few things that can cause it, And you have to check them as best you can before you power it back up. Check the blade, you can lay two blades together and check for gaps anywhere. Check that the hub and spindle are flat where the blade goes. (No lock washers) Also check the spindle for side to side movement, there shouldn't be any. Turn the spindle by hand and see if you feel any grit or sandy type feeling, you shouldn't. Lastly, if you don't find anything, try a new blade of a different type, and if it wobbles again, check and see if you have any warranty left and even if you don't you should contact Makita about it.
About the best I can do from long distance. Let me know what you find, Please.

Table saw blade wabbles alot when cutting?


This could be caused by several problems. First unplug the saw. Put a known straight edge against the blade (making sure not to contact the teeth) turn the blade slowly and watch for runout. Second make sure the spacers and blade flanges are on correctly. I would just about think it would be the blade. If you provide the model and brand I can do some more research. Good Luck

Bosh 4000 table saw , using dado blades.


no good solution for that problem. dado blades vibrate and cause the knob to turn. possibly a clamp on the knob to keep it in place.

Dewalt 708 sliding compound mitre saw


Probably a worn bearing. The only other thing that I have seen cause this is a bent spindle. This would usually occour if the machine has had an impact or if the blade has been suddenly jammed against a nail or something in the work that has caused it to jam and/or jump up.
A good indicator for bearing wear is to see how much play is in the blade in an up/down and side to side movement (unplug saw, safety first).
To check spindle, remove blade and run machine without the flanges etc on. Rest a scredriver gently on the shaft as it spins and see if you notice any (uniform) vibration.
