I asked my grandfather to bring down the tablesaw, because I want to build atleast 1 cabinet for the shop. He said he would look at the dump, since people throw cabinets away all the time. However, if he cannot locate one, then I am going to build it. However, he said he is nervous about it “flying apart”, because its really making alot of noise. He said it seems to scream now that he put the new blade on.

I know from the one at school, although its slightly better (A PM2000 compared to a Craftsman table top from 1950-60.. :) ), it hums, it doesnt scream really.

But I was wondering if anyone knew what it could be…?

My guess is bearings just from the noise. If it’s bearings, it probably won’t fly apart but it will seize up. That could be big problems.

”He said it seems to scream now that he put the new blade on.”

Some blades have BAD harmonics. They can have this annoying and deafening squeal.
Nothing to worry about, just annoying.

Okay: That might very well be, because, he bought the cheapo Sears Blades.. they were under $10…

Thanks, Ill pass it along, should it be the general concensus…

Why not put the old blade back on a retry if it still persists then it’s not the blade if it diapears then it most likely is the el cheapo blade.Alistair

I’m not saying the benchtop saw is ok. I couldn’t tell that without seeing it in person.

That being said, there is a different type of motor used in a benchtop saw compared to a cabinet saw. The benchtop will almost invariably be louder.

No doubt. I know that the bench top is a Direct drive, and the Cabinet is, I think belt driven(But the motor tilts with the blade, and the teacher says the arbor is comming out of the motor… but I didnt see for myself…) So w/o a doubt, there will be a definate noise difference… but From when I have used my Grandfathers, it usually was not THAT loud… although someties it got annoying.

1. Try a different blade.

2. Try running the saw without the blade on to see how loud it is.

3. Some blades are nosier than others especially if it has been resharpened.
