Thumb Screw Change Out on a Grizzly Band Saw

The Situation
Don’t get me wrong. My Grizzly 17” band saw (model GO513ANV) has performed well and been a pleasure to use. However, I wish Grizzly had used socket screws instead of thumb screws (shown in Photo 1) for adjusting the blade guides.

Photo 1 shows the thumb screws for the upper two blade guides, and the same setup exists for the lower two blade guides.

I just want to be able to apply a little more tightening torque than I can right now with the thumb screws, and socket screws would definitely enable me to apply more torque. I just believe that a little more tightening torque would go a long way in preventing the blade guides from possibly working loose from the screws holding them in place. Call me paranoid, but that is my concern.

Now socket screws are already being used to (1) adjust the clearance between the thrust bearings and the backside of the blade and (2) also to adjust the position of the front of the blade guides relative to the bottom of the blade gullets. So why not use socket screws for positioning the blade guides relative to the sides of the blade, also? That is the way I see it, anyway. Plus, I just like the look of socket screws.

Notes 1 & 2 in Photo 2 show the socket screws that came with the band saw, and both screws require a 5mm Allen wrench for tightening/loosening the two screws shown.

Notes for Photo 2
Note 1—The screw shown here is associated with adjusting the clearance between the thrust bearing and the back of the blade.

Note 2—This screw is associated with adjusting the distance between the front of the blade guides and the bottom of the blade gullets.

Note 3—Not the best of shots, but shown here is one of the replacement screws for the thumb screws, which are used to adjust the clearance between the blade guides and the sides of the blade. The replacement screws also use a 5mm Allen wrench for tightening/loosening the replacement screws. And that is nice that the same size Allen wrench is required.

In Photo 3 below, Notes 1 & 2 on Photo 3 show the socket screws that came with the band saw. Again, both screws require a 5mm Allen wrench for tightening/loosening the two screws shown.

Notes for Photo 3
Note 1—The screw shown here is associated with adjusting the clearance between the thrust bearing and the back of the blade.

Note 2—This screw is associated with adjusting the distance between the front of the blade guides and the bottom of the blade gullets.

Note 3—Again, not the best of shots, but shown here is one of the replacement socket screws for the thumb screws, which are used to adjust the clearance between the blade guides and the sides of the blade. The replacement socket screws also use a 5mm Allen wrench for tightening/loosening the replacement screws. Again, that was nice that the same size Allen wrench is required.

The Resolution
Finding socket screws to replace the thumb screws went smoother than I thought would be the case. After finding the required socket screw size (M6-1×16) from my Grizzly band saw manual, I went to Home Depot. And, lo and behold, they had exactly what I was looking for.

So I bought four socket screws from Home Depot. And I replaced the four existing thumb screws with four socket screws–two screws are required for the top blade guides and another two socket screws for the bottom blade guides.

The two new socket screws for the top blade guides are shown below in Photo 4.

And the two new socket screws for the bottom blade guides are shown below in Photo 5.

Regarding tightening and loosening of the four new socket screws, a 5mm Allen wrench is required, which is the same size as the existing socket screws referenced by Notes 1 & 2 in Photos 2 and 3.

Final Thoughts
I like the fact that an Allen wrench allows me to tighten the blade guide adjustment socket screws more so than with the thumb screws that came with the band saw.

The fact that the blade guides and thrust bearing can all be tightened/loosen with one size wrench, a 5mm Allen wrench, is also ideal.

And, as I said earlier, I just like the look of socket screws. Plus, this is a simple and inexpensive mod. At my local Home Depot, the four required socket screws cost me a total of $2 plus some change.

For the record, I have no financial relationship with any of the companies mentioned in this post.
