Topic tags/keywords: repair service bandsaw tools question

I am new to bandsaws. This one is the first I’ve ever had.

It’s a Grizzly G0513X2BF, 17-inch saw. I’ve been using it for light work for about a year. It’s had two blades on it: a 1/8-inch, 14-tpi regular tooth and a 3/16-inch, 10 tpi regular tooth. Light duty use no really thick pieces or hard woods. The 1/8 inch blade broke after several months. Installing the 3/16 – blade was a challenge to get it to track. But, it finally did.

Then I wanted to switch to a 3/16-inch, 4 tpi skip tooth. I can not get it to track to save my life. I replaced the tires and the blade still won’t track. it seems to track when turning the wheel by hand, but as soon as the motor spins up, the blade jumps off the wheel.

I know I should check for coplanarity, but I’ve never done that before, and I’d like to be back in operation quickly so my grand daughter and I can finish a project before she has to go home. Also, isn’t it a little early for a 1-year old saw to need coplanar adjustment?

Is there anyone in the Albuquerque area that could help?

Thanks

check your tension,and On mine the upper wheel is attached to a bracket with a upside down U that hangs over a post,I couldn’t see that till I played with it;but I couldn’t get it to track right either till I saw that,and made sure it was on right and then I could tension the blade and the tracking was fine. I.E check to make sure the wheels are set like they should.The co-plane shouldn’t go out once you have them working right.The gullet of the blade should be in the center of the wheel.and any gauge on the saw for tension ignore.and tighten by feel less than 1/8” left or right flex.

The wheels don’t need to be co-planer. Switch back to the blade that worked and finish your project, then you will have time to figure out what is really the problem with the new blade.

On those narrow blades you need to decrease the tension and track them where the bottom of the gullets are centered on the wheel. Then adjust your guides and you should be good. Overtensioning narrow blades is a common mistake (I’ve been guilty).

Thank you, everyone.

Over tension? All of the literature, including the saw manual says failure to track could be under tension. Anyway, I got the new 4 tpi skip tooth blade to track, somehow. It worked great for about half an hour, then the blade broke.

Over-tension? Could be. It was a little tighter than the 1/8 – inch blade, but still deflected about 1/4 of an inch. Could it have been a bad blade? Kink? After it broke, it relaxed into about four different kinks. Doesn’t matter, I’ll try again.

If your blade broke at the weld, it was a defective blade (I would return it). Timberwolf will replace blades that break at the weld (or at least they have in the past, haven’t broken a blade for a LONG time). Did it get kinked when it came off the wheels?

Yes, it looks like it broke at the weld. And, there were three very obvious kinks when it came off the wheels.

A gentleman named Mark Nowicki on another service sent me this link : https://www.youtube.com/watch?v=wGbZqWac0jU

I followed the instructions there and had a new blade installed tensioned and tracking in minutes.

Have your say...
