Topic tags/keywords: grizzly go555lx bandsaw vibration grizzly bandsaw issue

Excuse me if some similar topics have been posted, but I was hoping to get some specific advice to my situation, and have also searched topics of this nature on various sites. A little bit of background for me is that I am a general carpenter but am pretty new to fine wood working, thus am familiar with general carpentry and tools, but less so with shop machines, I am in process of getting my shop going. Please excuse any issues with clarity or spelling/grammar etc. my bandsaw troubles are really making me loopy…..?

2 days ago I received my grizzly go555lx and assembled it that night. Shipment had no visible damage to the box, nor did any of the contents inside. It’s a 14” 1hp with cast iron wheels, mounted on immobile base. I’ve removed the supplied rubber feet and have it sitting on 2×6 skids.

I set the saw up as instructed in the manual, checked for wheel allignment, coplanar, blade tracking, guide bearings etc. and when I turned the saw on I had less than desirable results, however not horrible results either. One issue was with table vibration, and the main and more troubling issue was that the saw vibrated violently about 3/4 of the way through its shut down process.

After speaking with grizzly tech support on Friday Ive spend the whole weekend working on the saw and trying to isolate this problem. At this point I have: checked blade tension, tracking, bearing positions, checked blade for poor welds and over all shape (despite it being a low quality blade, does not appear to be malfunctioned), coplanar, allignment, belt tension, pulley allignment, bolt and nuts for tight, proper motor mount, secure stand etc. I’ve gone over everything to my knowledge and have discovered these findings thus far.

I removed the blade and ran the saw with just the bottom wheel and it seemed to have the same issues as stated, but less magnified. I tested the bottom wheel for balance using the bottom wheel shaft as my mounting point. I have determined that my bottom wheel does appear to be unbalanced (assuming I can use the saw the way I did to accurately check). I marked it its heavy point, tested it multiple times and it always drops to the same spot (Have not checked top wheel). I have run the motor by itself and some vibration seems to occur, but not enough to make me believe the motor is at fault. With that said, I thought I figured out the issue, and began bragging to my girlfriend about how clever I am and figuring it to be an unbalanced bottom wheel. I tried to balance it myself by wrapping electrical tape several time around tops of opposite spokes. Using the same method to check for balance, it appeared I had succeeded however when I set it all back up I still seem to get a really bad wobble during the shut down process.

I have also noticed that there is a little bit of play from side to side between the lower wheel and the shaft, but I believe I alleviated this when I tightened the belt. But still the same results.

As of right now I am having my best results, but the over-all issue is still apparent. I have tightened the belt by moving the motor back a bit, (but still believe I have enough play as followed by manual), aligned the pulleys to the best of my abilities ( only by eye, BUT done so with a carpenters eye) ‘balanced’ the lower wheel, and secured the saw to the stand and the stand itself (all level) as best I can short of bolting it to the ground. My results thus far are that sometimes I can balance a nickel on the table for minutes at a time, and sometimes only a few seconds, but always end up with a pretty substantial amount of vibrations during shut down. It basically feels like the wheels are wobbling really bad and are looking for some other place to go, which then runs through the machine and then stops once a certain speed is hit. I do not have a method of measuring accurately the wheels other than checking for balance.

At this point I will go ahead and speak with grizzly tech regarding my findings, but also wanted to get anyones thoughts on this situation regarding trouble shooting, and also whether or not this issue is even that problematic in regards to bandsaws of this nature (price point, quality etc.). I was hoping to hear from anyone with the same saw and hear whether this sounds like a common issue or not and lastly being that the saw is so new, whether this amount of vibration warrants a possible return, or is minor enough to where I’m better off keeping it and living with it. I’m not trying to be picky or obsessive about this issue, but at the same time $550 is a lot of money to me at this stage in my life, and my shop is going to cost a lot more to set up. If this were a common issue for these saws, then it would not bother me, but it’s hard to live with this issue if I were to know that it is not a common problem with these saws. And lastly, I like the grizzly company, I’m really hoping to figure this out because I want to trust the grizzly brand, because is was in fact going to look into more of their tools for my shop. Anyway, I’m sorry for the long post but really Any help or input would be greatly appreciated….this little bandsaw riddle sure is getting the better of me right now.

Thank you.

I have the LX, and it has been trouble free. Contacting Grizz Tech services is your best bet.
Are the wheels firmly attached to the shafts? Nuts and set screws tight?

Yeah I’ve checked that as well. Spoke with tech support again and they suggested maby the belt was bad. I’m gonna look into that. I’ve had mixed results with tech support, it feels like it’s just too difficult to diagnose a problem like this without being able to see the machine in person.

The fact that you get a lot of vibration on shutdown might indicate a bad bearing. Just a thought.

Thanks for the suggestions. Since I’ve recieved the machine I have been neck deep in trying to get this thing to run properly, hours upon hours of tech support and personal investigations. just yesterday I noticed the motor was not turning on properly and with investigation found that the centrifugal switch and accompanying components were looking rough and the machine was clicking and sparking while starting, after adding this repair work to my list, And hearing the news that parts for this would be back ordered a few weeks, I finally got pretty overwhelmed with the amount of work I felt I had to do on this brand new saw. I simply called Grizzly CS and explained my experiences over the past week, and noted that I have yet to even cut a single peice of wood with it. The agent and I agreed that it would probably be best to just exchange the machine for a new one consider the issues I’ve been having in such a short time of owning it. So as of right now, Ive got to say, I’m happy to hear that I’ll just get to go ahead and recieve another machine. Before this new situation, I was getting pretty down on grizzly, and bummed out especially since I’m in the process of putting my shop together and was going to be looking into more grizzly tools. But assuming all goes as planned, I’ve got to say, despite these early issues, considering how CS has kind of had my back through this, I still consider grizzly to be a stand-up company. I’ll make sure to leave a review once my new machine is delivered and set up, and hopefully pictures of my new shop as it gets put together. Right now I’m in the process of framing a couple walls and running for more electrical.
