I bought a used rigid 3650 about a year ago. I had no problems with it ( that I noticed) until one day I had a kickback. Ever since then it’s had a blade flutter or more of a hermonic (it comes and goes once I hear it comming I stop the feed but it amplifies enough to ruin the cut and then stops). It doesn’t happen when Im plowing through a cut at a good rate, It’s only when I’m going slow, trimming less than 1/8”, or on thin material. I’ve tried new blades, aligning everything to .002” or less, new bearings, new arbor, adjusting the belt tension, tightening all bolts, and checking for any runnout or excess play. I’ve got this thing adjusted perfectly. The only other thing I can think of is maybe getting a stablizer for the blade. If anyone can give some other options I’m open for sugestions.

Oh, the blade is a new Freud 1/8’” kerf, but it does it with other full kerf blades too.

Have you replaced the belt ? —It may have a “weak” spot in it

I am shooting from the hip here, but….....

1. Is the belt glazed over, or any strange looking wear patterns?
2. Trunnions tight to the table?
3. Motor secure on it’s bracket?
4. Possible pulley loose?

Really hard to tell without seeing it up close and personal.

Good Luck Yammi, I hope you get it figured out.

No idea really, but belt was one component that entered my mind….it’s cheap and easy too.

What Shipwreck says.
If you find out what it is, let me know. I have a 3650. So far no problems though.

I’ll try replacing the belt, but everything else is tight.
Thanks for the input. I wonder if the belt is a special order thing.

A lot of times a well stocked auto supply store might have a replacement belt for machines

Try a link belt. HF has an inexpensive (notice I didn’t say cheap) one, that gets great reviews. I just recieved one that will go on my TS.

The belt isnt a v belt, it’s a 1/2” ribbed belt like a serpentine belt

Have your say...
