Hi,

I have a G0555 with the riser kit installed giving me a blade length of 105” and I use Timberwolf 3/8” 3 tpi blades.

When the first blade broke after about 4 months or so, I thought that I was doing something wrong – maybe feeding too quickly or working against the blade drift, but after breaking about 3 more I figured that something had to be wrong with the saw.

I checked the wheels to make sure that they were coplanar – all good, and then found that the stock bearings were binding from dust. I changed the bearings to sealed ones which have been running free since then but I still lost a couple of blades.

On closer examination, I have found that when I change the height of the guide post either up or down the bearing adjustment is lost – they either rub the blade and spin even without load or they do not touch the blade at all.

I have been searching to see if I can find anything that addresses this problem but cannot.

Would appreciate any assistance.

Thanks

Steve

I’ve had G0555 for more than 10 years and haven’t broke a blade yet. While you didn’t say which bearings you changed, I suspect it was the guide bearings. I doubt that is the issue.

I suspect the issue is with the blade tension, too loose (most likely) or too tight (and it really needs to be way too tight) are probably the culprit. What ever you do, DO NOT use the tension guide on the saw as it will not provide enough tension to properly tension the blade.

Try using the Snodgrass method to setup the saw and tension the blade.

Good luck…

Hi WoodES,

Ok, I rewatched that video as well as this one and will try those methods tomorrow.

Thanks

Steve

Steve, I have the same saw with the riser. I had a terrible time with Timberwolf blades on that saw for some reason. It may just be my saw because I know a lot of folks use them with the G0555 but I spent days trying to figure out what was wrong with the saw. My issue was terrible cut quality and tracking was all over the place. Finally I tried a new blade of another brand and it’s been aces ever since.

I’m not trying to bad mouth Timberwolf, they make good blades that work for lots of people. Just giving you my experience. Best of luck!

HokieKen, which blade did you end up with?

I went with the 1/2” Woodslicer Blades for resawing and the 3/8” Woodturners Bandsaw Blades for cutting green wood for turning stock. Both from Highland Woodworking. The saw came with a few 1/4” and a 1/8” Olson blades that work well.

I highly recommend the Woodslicer for resawing. Otherwise, the others all work well but I don’t see anything special about them. I think the issues with the Timberwolf are that they’re meant to be low-tension blades and something about my saw just doesn’t agree with them.

Did they break at the weld?

I have had very little experience with Bands Saws,
What happens when the blades break? can they take the operator and saw out? Or is it benign and contained in the casing??
Regards
Anthony

Assuming the guides and wheel covers are in place, it’s a benign event Anthony. It makes you crap your pants but the blade stays contained. At least in my experience…

@HokieKen,

Will try the Woodslicers and see what happens.

@wncguy,

Yes, generally at the weld. Don’t know if constant contact with the bearings heats the blade up enough to weaken the weld.

@anthm27

What HobieKen says, quite benign, but the first time it happened, I pushed the off button and was done working for the day!! When the blade breaks it sounds as if the saw has broken in half.

Are you seeing any deflection or do you hear any rubbing or grinding noises right before it breaks (or any time for that matter)? If not my first guess would be too much tension but it sounds like you have bigger problem. The bearing alignment should not change simply by changing the guide post height. That tells me that something may be bent, perhaps from too much tension, or maybe the riser is not installed right or is not the correct riser for your saw? Make sure that the table is set square to the blade and set a try square or adjustable square on the table next to the guide post. When you adjust the height of the guide post, see if the the distance stays the same at all heights. Check it side to side and front to back.

S,

If your blade is in constant contact with the guide bearings the setup is incorrect. The bearings should have a very small gap between the bearing and blade. Constant contact with the bearings sounds like a loose blade condition. Remember it is very difficult to overtension a blade with the hand wheel.

I’ve run timberwolf and Starrett blades for some time and haven’t had a problem. I also have the riser on my saw as well.

Know that the blade tension adjustment on most of the 14” Delta clone band saws is woefully under tensioned. Snug it up more by at least 1/4 of the suggested, and do Alex’s guitar string twang, or push inward to check for tension. Know also that you can OVER tension one too, so it’s a sweet spot. I usually go to the 3/8” mark on a 1/4” blade at least. then check for deflection. What happens when under tesnsioned is as you push the work into the blade, you can actually get it to start turning sideways if it doesn’t have enough tension. Your guides will just chew it up if it does that, especially if you have the harder metal guide blocks that come on the saw.

If you find it though, and all other portions of your set up are good, drift as it is explained by many, just goes away.

I have heard many say that those Timberwolf blades have poor welds as well, which even if you are set up correctly if that weld is going whap whap whap every time it goes through the guides, it won’t have a long life.

I don’t know what the price differences are, but I don’t care for blades on a blister card where you have to accept someone elses idea of the correct blade. I like going to a place where they make them for you per order, and have folks on hand who if they know what saw you have, and what you want to do will make suggestions for the blade they like, but you have so many more choices as to blade stock, and price point. A few I have heard of good results, or have used myself.

Steve – you might want to contact Timber Wolf to see what they have to say…
Seems like I recall some sources say they will replace blades that break at weld.

Never had any blade breaking on mine (yet), but it did track terrible after I added the riser until I installed a stiffer tension spring.
