Topic tags/keywords: tablesaw alignment left tilt tablesaw help

Lumberjocks,

I own a Delta Contractor table saw. the 36-979. My left tilt wheel has been getting harder and harder to turn (more and more friction on it) I have cleaned it as best I can and as far as I can tell that is not the problem. I got underneath the saw and to me it looks like the worm drive screw (?) is not properly lined up with the tilting mechanism. How could this have happened?

I did recently square up the miter gauge by loosening the trunnions and bringing the top into alignment. The saw has worked great for several months after I did that though. Could this have mis aligned the tilting mechanism?

Here is a picture from directly below the tilting mechanism. The screw over hangs the tilting mechanism by a decent amount. In the picture you can see where the drive has rubbed and created some shine.

Also, another symptom of the problem, I just recently broke my roll pin off in the wheel adjustment due to the excessive friction ( I should have stopped but you know how it is when that project just needs a few more cuts)

I appreciate any advice/help.

Is the lock released, unscrew the lock knob to and make sure its coming out, I have seen the knob strip off of the shaft but not fall off, you could turn it but the shaft won’t, the lock knob should not be over tightened just snug

One last bump for some help. Friction in the tilting wheel. If anyone has any advice on what can cause this besides grime.

Don’t know. I have a Delta contractor but the tilting wheel is easy to spin, it’s the front blade height wheel that is sticky.

DavidTTU, “One last bump”? Aren’t you expecting a bit much from a forum that doesn’t charge you for joining?

A lot of the members only get on line once a day or every two day or so.

If you don’t have the ability to have patience, maybe you are in the wrong hobby.

Most worm gears can be off center from the driven gear a little. The picture makes it look like the worm is off to left but fairly square. The worm gear must be perpendicular to the driven gears shaft. As long as the teeth mesh they are not shifted. Is there play in the worm on its drive shaft? Is any other part of the motor, belt, blade etc dragging on another part of the saw body?

Maybe Delta can shed some info on the situation.

Dallas, no harm was meant I am just trying to get back to work in my shop.

Chris thanks for the help. There is no play in the worm, and no other part of the saw is dragging. The last picture scares me the worst, because it looks like the initial screw of the worm is bent. The whole worm gear is very out off of center. Is there a way to bring it back into center?

Would there by any chance that the trunnion mounts that I recently tightened up after bringing the table into square with the miter gauge could be causing the problem?

How common is it for a wormgear to bend? Can you replace a worm?
