Topic tags/keywords: grizzley bandsaw

Back in November I bought my new G0-555P Bandsaw at the Grizzley store in Muncy, PA. Since then, I haven’t had a chance to use it since my honey-do list items had been backing up. This past weekend, I needed to make some plywood edge banding from some 4/4 maple I’ve had on hand for a while. So, I pulled out the Grizzley and I noticed something really curious.

I loosened the two locking screws under the table, placed my square against the blade, adjusted the table top and then tightened the screws. And immediately noticed that the table was about 2-3 degrees out of square.

Hmmm…

After a little more investigating, I discovered that tightening the rear (with respect to the front of the saw) screw was pushing the table out of square. Not having a lot of time, I managed to compensate the adjustment of the table so that tightening the screw drew it square. I cut my edgebanding without incident.

But it’s clear that I have a problem. I’ll need to disassemble the top and check for proper assembly, play in the pivot and any other issues I can find.

One more strange thing that I didn’t notice while doing the initial assembly is that the rail for the fence sits slightly proud of the table top. That will get investigated as well.

The lesson is that one can miss some important things in the initial, hyper-enthusiastic phase of product assembly and setup. I’ll have to remember that in the future.

Stay tuned…

Please keep us posted, I’ve been scouting out this band saw for some time now and it’s still on my radar.

Yes please keep us posted! I had no problems with my Grizzley machines, although I did not purchase the same model bandsaw.

When ever yoiu tighten a bolt head or nut, you can turn what ever it is against as it tightens. Is that the trouble?

Sorry, I don’t have a video camera. Watch when you tighten a bolt with a wrench. When as it gets tight, it will sometimes move the surface the nut is against or even the surface under a washer if it has a good bite on it and the surface is small enough and mobile. Typically things that can be adjusted will move slightly sometimes, especially if it is a critical location. I usually anticipate how much the movement will be and start tightening a little off in the negative position so it will draw up tight to where I want it. You might not be able to tighten it perfectly, that is where a block of wood and a mallet comes in handy to make a fine adjustment if it is something that is appropriately WHACKED lightly :-))

From what I could see, when I tightened the rear screw, it lifted the trunion off the semi-circular casting on which it rides. In other words, the table ends up resting on the end of the screw, not the casting.

I promise to take some pictures this weekend.

What the screw should do (I’m going on memory here, not having the saw at hand) is pull the trunion down into the mating casting. What’s actually happening is that tightening the screw is driving the table upward, away from the table support.

I’m going to have a look at Grizzley’s on-line parts diagram and see what I can figure out.

Well, the mystery is solved. Chalk it up to operator error. The 90 degree stop was set too high and it was acting as a pivot as I tightened the locking screws.

The problem with the fence rail is also a function of operator error. When I was assembling the saw. I didn’t notice that there were two sets of holes in which to screw the fence screws. Doh!

All is right now and the saw is purring like a kitten. The lesson, again, is to not let the excitement get the best of me when unboxing and assembling a new toy.
