Topic tags/keywords: question

Brother and Sister LJs, I recently acquired a Freud Premier Fusion, Thin Kerf, 10” table saw blade for my Grizzly G0691 machine. When I think it is securely installed correctly (yes, the outboard balancing washer has a groove for the arbor nut to enter and engage to center everything up and that’s done correctly), I’m hearing a very loud screaming/screeching noise for about 1/2 – 1 second at start-up. I’ve never heard this with other thick/regular kerf and dado set blades. Can ya’ll help me find out what’s wrong or I’m doing incorrectly?

A loose belt ?

I immediately wonder about three things. I’ve not had direct experience with this blade, so there may be some unique properties. My first impression is that the blade may not be tight enough and for a split second is lagging behind the arbor. This would also mean it would lag behind the arbor in a heavy cut. A quick disassembly to check for circular wear rings on the blade would be in order.
An alternative is that by coincidence your drive belt has begun to squeal. Check the tension.
Another alternative is a bearing that, again by coincidence, is dry and beginning to chirp.
I can also imagine that the air patterns around the blade are different from what you’re used to, and until it reaches the optimum speed for which it is tuned, the air vibrates at a high frequency.
And there is always the possibility that there is something touching the blade momentarily.
Good luck. Sounds like a good puzzler.

May have to be a process of elimination of the usual suspects outlined by Dan above. From experience, don’t over look the obvious though, its probably somrthing simple.

As a matter of interest, does the blade noise reappear when put under load when cutting or when you have shut the saw off and the blade coming to rest??

replace your old blade then switch on, this may indictae if it’s the new blade or the saw. Maybe worth operating the saw with out a blade fitted also.

I would also remove the blade washer and give it a clean, could be debris trapped between the blade and securing washer/nut. Like I said don’t overlook the obvious.

Good luck.

Thanks for all the answers thus far! No after replacing a thick kerf blade no noise, Yes there is evidence that I failed to mention of circular rings where the thtush washers reside on that blade but not on any others that I’ve used; No, it doesn’t scream when under load even with 5/4 Pecan/hickory or and pine or cypress. I’ve cleaned out the “S” slots which ca,e clogged with finish lacquer. There seems to be no runout or wobble and it really cuts beautifully. I don’t believe it’s the belt or bearing but it maybe. The saw is about 18 mos old and I’m its first and only owner. I’ll keep investigating and keep things up-dated as I continue to persue this. Again THANKS!

I believe those slots are supposed to be filled some sort of a flexible calk-like material. I could be wrong, but if not, it’s a possible contributor.

Lower the blade all the way and try it.

You may need a stabilizer. They do reduce noise on some
blades.

Your new blade is thinner than the old one, perhaps the nut will not seat all the way down against the new blade, maybe some mfr saw defect or some gunk in the threads? Just a guess.

If all the excellent problem solving suggestions do not work there may be a possible distortion in the blade? If you can replace the thin kerf with another thin kerf and test it may be the blade balance. In which case I might contact the manufacturer. Especially if its an expensive blade.

Doc, When installing a thin kerf many toothed, lots more than 80, Craftsman “Plywood” blade, there’s no noise as with all other thick kerf blades I’ve used. Once the noise passes about 1/2-1 sec it performs beautifully. I’m really impressed with the fine cuts both rip ans cross cut in many types wood.

Aah! “Happy Days Are Here Again!!!” After reviewing all the suggestions once more, I lowered the blade, noise still there, then I removed the blade and thoroughly cleaned the arbor fixed washer and outboard washer and saw blade with Isopropanol and reinstalled the the blade EXTRA tight, as there was evidence of the wear circles where the washers ride showing some appearent slippage. On start-up several times with the blade in several different heights and the regular insert and ZCI installed NO noise. WOW!!

Agauin I really appreciate these fine diagnostic adventures. Ya’ll are just super people.

I’m thinking blade balance? Good luck.. Hmm plywood blade would produce super fine cuts. Was going to suggest comparing thickness of cut? Or using a dial gage if you have one? But maybe it doesn’t matter LOL!

Hey just wear your ear protection LOL!
