With the help of this forum I was able to fix the tension issues my new (used) bandsaw was having. I have hit another wall that I could use some advice on. The blade is now rubbing against the return blade guard once I have applied tension to it. I have spent a while adjusting the tracking / tension with no luck.

Here is a video of what I am talking about, the first few seconds show the blade rubbing as it comes off the bottom wheel and the end of the video shows the blade passing though the guard with no problem as it exits the guard and goes onto the top wheel: http://youtu.be/lZ-ehGZcdcM

I have a few theories but I am new at this so they probably dont hold water:

1. Blade guard is warped and needs to be replaces (it appears straight so this one is a long shot)
2. I noticed that the upper wheel is slightly more to the left than the lower wheel but I do not see any way to adjust either wheel since the lower one is fixed and the upper one only has a tension and tracking adjustment (no left / right adjustment).
3. I read that the wheels need to be coplanar which they appear to be when I use a straight edge to ensure they are on the same plane.

Thanks again for all of the help.

Iturra sells a machined hinge for the top wheel that you can shim with included washers to move the top wheel axle left or right thus moving the top wheel left or right. I resd an old article where the author suggested moving the factory hinge left or right by grinding off material from the hinge and then shimming it to move the top wheel. The bottom wheel I don’t think can be moved left or right.

Tom got it right. I remember seeing that in Iturra’s catalog, thinking it was pretty slick.

You can take a look at the Iturra catalog here. The machined pivot hinge that holds the wheel shaft is described. I’m not sure if it will fit a Jet. You’d have to call Iturra.

Or just shim the bottom of the blade guard so it doesn’t rub.. shouldn’t be too hard (or expensive).

Inside the mounting housing for the blade guard there shout be a screw that attaches the guard to the saw frame. It is slightly adjustable. Shine a light in there, you should see it.

Thanks. I adjusted these to pull the guard as far right as it will go but the blade is still rubbing. Does anyone have an idea of what causes the blade to rub in the first place? I can shim the guard but I am more interested in fixing the root of the problem rather than adjusting my saw to compensate for it.

Thanks

The catalog link on that site is no longer working. I need to order some bearings for the saw anyway so I’ll just call him and get a catalog with the order. Thanks!

I had the same problem on mine but in the other direction. I just took it over to the oscillating spindle sander and opened up the hole in the hole in the plastic to allow it to shift over.

I certainly would NOT start messing with the wheels. I still think something is amiss with the mounting of the guard. With the blade off does the lower wheel have any play?

Please forgive me in advance, but do you have tires on your wheels.

You are forgiven and thank you for not making any assumptions :) The tires on my wheels both look great!

You are spot on. I fine tuned the bolts holding the guard to the frame like bdresch and you suggested, that fixed the problem :)

I have watched his clinic about 3 times now. Very good information.

Have your say...
