Sometimes you can't see the forest for all the tree's. The double bearings used for blade tracking (if not exact at 90*) are going to make the old vibrating bearing moan (squeeling if you like).. Oil and lube will work for a short while but won't cure the problem.. New bearings will work for awhile but won't cure the problem.. Reworking the problem by Shopsmith will work for awhile but won't cure the problem.

In fact there can be more then one issue at a time to correct but once you know the bearing are all new then the only issue then has to be alignment on the tracking bearings, Vertical and at 90*,,

My saw, used runs quiet and smoothly. and I use the cheapo olsen blades.

Vertical and at 90 degrees - 90 degrees to what?

I think you are saying that the double bearings (blade tracking bearing/left side) must be in a plane that is parallel to the face of the blade.

The bearing 90* to the blade! once you get the blade in the groove and the bearing is exact and vertical with the blade then use a square against the face of the bearing and check it against the blade being at 90* this will assure no side pressure on the bearings. Once I did this and found the bearings "not to be a perfect 90*, I made adjustments and the moaning stopped!.. No friction and smoother running tracking bearings.

I would think the axis of rotation of the bearings perpendicular to the sides of the blade in BOTH directions(horizontal, AND not rotated AROUND back).

Hope that makes sense! Not easy to put into words.

Dusty and all - I wanted to post what i found yesterday and today with my bandsaw - more particular that double bearing of discussion.

1) I opened the cover and observed the 1/2" blade I had on. It ran perfectly in the depression in the bearing.

2) I did the same thing with a new 1/4" blade. It would run in the groove, but If, when stopped I pushed the blade over to the inside bearing part, it would stay there when running. Pushing into the bearing slot again it remained there while running.

3) Today had to use a 1/8" blade. It has been used before, but looked straight except for a couple of little bends. When running this blade continuously shifted from the bearing slot to the inside and back.

There was no weird noises coming from the saw until one time with the 1/4" blade operating on the inside part of the bearing. I tried to get that howling noise again but to no avail.

No. It removes any burr on the back edges that can grab on the tires and effect tracking.

I would be remiss if I failed to point out that this thread has not had any activity since March of 2009. That’s nearly 10 years ago.

Much has been discussed on the bandsaw since in numerous newer threads.

My suggestion would be to open a new thread geared to your problem area if you have one.

Kindest Regards,

Everett

Thanks, Everett, I did review a number of threads re:bandsaw issues, just wanted to catalog a few for future reference.
