Banging noise

[courtym74]

My Delta 40-694 20 inch has started making a banging/rattling noise. It is not constant and the intensity varies as well. Even on the same speed. I've had it apart half a dozen times looking for the issue but so far nothing! No worn spots, broken off pieces, etc.  It doesn't seem to affect the cutting or accuracy but sometimes it honestly sounds like there's a bag of marbles bouncing around in there.  Anyone have anything similar with theirs? I've seen a few threads with other brands but curious if anyone has problems with a Delta specifically.

I have that saw and recently experienced something similar....

The motor on mine was loose. I didn't notice it until I heard the "banging" noise.

I took it apart, tightened up the hold down screws and no problems since.

Other than that, not sure what your issue could be. Perhaps someone with more XP will chime in...

I retired & gave my 40-694 to a son.  Here is what I had to do;

Remove the switch.
Remove the tension lever.
The tension rod was hitting the metal below the switch & leaving a mark.
Pushed the rod to the side & filled a groove in the metal with a chainsaw file. 

That cured it for me, but not sure it sounds like your problem.

I had to tighten the motor on the delta that I have at school. I don't remember exactly what the symptom was that I was fixing but it helped tremendously. Before I tightened it I could grab the motor and wiggle it back and forth so it was really loose.

I think it might be aliens inside the saw.. when you took it apart they seen you and got scared so they ran deeper into the saw to hide.. You should just take it apart and leave it for a month so they have time to escape.

Since your saw and the Dewalt are clones there is a ton of useful info on scrollsaws.com. I think both of the suggestions that have been suggested so far are valid but check out the other hints there for further reference. Get familiar with your saw.

I have a question for you.  Where do you buy your weed?  Do they have a site that I could order from?
