View Full Version : trouble tracking narrow blades on g0555

I have a fairly new g0555 that I have never used much until now. I removed the 3/8 blade (which has always worked fine) and put on a 1/8 blade to do some fine scroll work. I was not able to keep the blade running on the center of the tires. I'd adjust the tracking angle in very fine increments about 1/10 of a turn, and when it began to approach the center of the top tire it would suddenly slide to the other side, regardless of the tension on the blade. At this point I took the blade off and checked the saw for coplanar alignment, as I had never done that. It was off about 1/16 inch, so I added a small washer to the top wheel and it was then coplanar according to two straightedges. I cleaned the tires with mineral spirits and made sure everything was tight and running smoothly, put the blade back on and had the same result. I put two different 3/8 blades on and had no problem with either. Unfortunately I don't have another 1/8 blade on hand immediately. Is it likely that it is the blade, or is there something wrong with the saw?

Thanks.

Zach,

I'd call Grizzley and get the opinion of one of their technicians. I'm sure they have dealth with and answered this more than once.

Check the weld on your blade. If it's proud even a smidge, it can throw you off. I have this problem on my 3/4" blade on the G0555. Mine doesn't slide off; it moves back and forth. I suspect there's enough width on my blade that it corrects itself over a rotation which results in back and forth movement.

On your narrow blade, it might only take a tiny bit of imbalance to push the entire mass of the blade to one side of the crown after which point it's all proverbially downhill...

Just a thought.

Common problem with narrow blades. I had that style saw once, and had the same difficulties. All I could do was play with it, and get as close as possible.

So if I get it as close as possible, is it preferrable to have it left or right of the center? I may have to have it left of the center, as I am not sure how much play the bearings have, but it has been a few days since I have played with it so I don't remember for sure. Is there anything dangerous about having an off-centered blade?

As said, its not an uncommon problem with narrow blades on crowned tires. I just make sure my blade is stable where ever it wants to ride. It's not a big issue and really makes no difference.

If your saw has crowned wheels, which are very common it will probably never want to track on the center. It really isn't a big deal if it doesn't what is most important is that when you get it to track were it is happy that it stays there. Bandsaw guides have a lot of room for adjustment so that should not be a problem.
Bandsaws are not like a tablesaw where you can just put a different blade on it and start cutting, you will almost always have to make a few adjustments when changing blades especially if you change widths.

Thanks, everyone One more question:

Is this saw likely to benefit from aftermarket tires?

Zach,

If the saw is fairly new, the tires should be okay. I will caution you about cleaning tires with solvents.

If the tires are rubber, I'd just use a mild soap and water mixture to clean them. From a lot of experience on 1/2" computer tape drives ....don't clean rubber with alcohol and be cautious using other solvents....alcohol hardens rubber rather quickly.....other solvents can soften it.
