Well Guys, I need your valuable input on a problem. I have a Rockwell Table Saw I bought in 1994 so it is nearly 20 y/o. It has served me well and been an excellent tool. Other than a few kickback problems (I caused by carelessness) it has been problem free. Many years ago I removed the blade guard and it seems to be no where to be found. Not a good idea but 20 years ago I thought I was nearly bulletproof and did a lot of dumb things. Now at 76 I can see the error of the bulletproof theory. Anyhow my problem is the saw vibrates. And badly. With Parkinson’s everything trembles, some days worse than others but this is definitely the saw. Any tools or wood on the side table vibrate and frequently fall off. And it is noisy. I have put a better quality blade on it and it still vibrates. I changed out the old belt for a new one and it still vibrates. I have anchored the saw and side table better to the floor and it still vibrates. Now I don’t know what to do next and here is where I need your collective advice. Anybody got any suggestions? What can I check or look for? Getting up under the table is too tough for me but my grandson can do that. I will try just about anything at this point.
Replacement of the saw is not practical at my age, moneywise and longevity wise. Thanks

I would take the belt off and turn the motor on and see if the vibration is still there. Also, unplug it and manually turn the motor and see if you feel any roughness. If you don’t find anything, I would grab either the arbor pulley or the blade with the belt removed and see if there is any roughness or loose bearings. That should help you narrow it down.

Have you tried to run just the motor without the belt and the blade?worn out bearings can cause vibration,my rockwell TS started to vibrate after we moved to our new home,it turned out to be a misaligned pulley .

Hey Guys, Thanks for the suggestions. I tried all that you suggested and found nothing loose or out of alignment. I then put the old belt back on, moved the whole saw around on the floor, made sure out tables were secure, checked the blade for any run out, lubed all the parts that were dry with the dry lube I use on my planer shafts, plugged it back in and kicked it on and the vibration has been reduced by 80%. What vibration it still has is something I can live with. Y’all are always full of help….thanks.
