Topic tags/keywords: grizzly bandsaw g0513x2 setup

Hi all,

I recently purchased a Grizzly G0513X2 17” bandsaw, and have a few setup questions …... all responses appreciated.

a) For blade tension, I tried the “fluttering method” recommended in the manual, but in practice it was not so clear when the fluttering would really stop ….. it seemed to stop then if I tensioned more it would start again, stop again …..not very clear or repeatable. Using the deflection method, I ended up with a tension that read about 4.5 on the blade tension scale – but the blade was wandering all over the place just ripping a 2×4. I will try increasing tension but am wondering what sort of settings (or methods) others have used? (Note – I’m still using the stock 1/2” 6 tpi blade that came with the machine – better blades ordered but not arrived yet).

b) it seems very hard to access the upper support bearing with a feeler gauge to set the distance behind the blade, because the red housing on the guide post is in the way. Am I missing something obvious here?

c) The blade speed is on the default setting, which is the fast (3500 fpm) speed. The manual suggests changing to the lower (1700) speed for some operations …... I was wondering if anyone actually does this?

d) The tension lever is excellent for quickly releasing or applying tension …... but makes it easy to accidentally turn the machine on while the blade is not tensioned. Not sure why they haven’t built in a lock out mechanism to avoid this. Anyone have a practical suggestion to avoid this ….

Thanks!

I’ve had the same saw for about a year now.

Tension: You’ll get to know what tension each blade performs best at over time. I guess you can say I start with the flutter method but once the flutter is gone I listen to the saw. I keep cranking until sound of the running blade changes then back it off a ¼ to ½ a turn. Not very scientific but like I said you’ll get familiar with it.

To get you started… I mostly run a 3/4” wood slicer at a setting of about 7-8 on the scale. Secondary to that, I have a 1/4” blade I run somewhere around the 4 mark. I suggest cranking your tension on the 1/2” blade, SLOWLY (quarter turn at a time), up to around 5-6 and see if the flutter, harmonics, or performance change. Make sure all of the guide bearings are well out of the way while figuring out your blades initial tension setting.

Setting guide bearings: No need for paper, or feeler gauges, adjust the bearings so that they just touch the blade paying attention that it doesn’t actually move the blade, then back off so that you can just see light between the blade and the bearing. I do this for all 6 bearing adjustments. It’s surprising just how accurate your eyes can be.

Then Turn on the saw, if any or all of the bearing are spinning at a rate comparable to the rate of the blade, that bearing needs to be backed off a bit. In my experience blades are seldom with in tolerance that feeler gauges will decide the final guide setting.

Blade Speed: Never changed it.

Tension quick release lever: I’m guilty of having turned the saw on without tension once or twice. Fortunately, no damage ensued. My only suggestion, make it part of your routine that every time you walk up to the saw, that the tension lever is the 1st thing you look at. Even touch it even though you see it’s the down position just to enforce the habit.

It’s a great saw, hope you enjoy it.

Here is the obligatory band saw setup video:
Band Saw Clinic with Alex Snodgrass

It discusses blade tension, position, tracking and guide setup.
As for the quick-release tension thing – easy fix – just don’t de-tension except when changing blades :)
Others have other methods… like unplugging the machine and draping the power cord over the tension lever to remind you. Whatever works.

Cheers,
Brad

I like the Snodgrass video, but he says to set the center of the blade gullet into the center of the wheel …. but the bandsaw manufacturer’s manuals i think all seem to say to put the actual center of the blade in the center of the wheel …... which for a large blade seems significantly different. Not sure who to believe.

Tension quick release lever: I turned my band saw on once with no tension on the blade, no damage but definitely do not want to do it again. I just tied a piece of red colored rope around the release handle and whenever I release the tension I just wrap the other end of the rope around the front of the blade
