I'll have to look at the locking mechanism on my fence tonight and refresh myself on how it works. I do recall that there are some nylon pieces that hug the back of the rail and the locking cam hits the front and pulls the nylon tight to the rail. It sticks in my mind that there is some adjustment for the nylon pieces to account for wear but I could be mistaken. I'll try to look this evening and report back.

Okay, I flipped mine over and had a look. You can see that the brass on mine is well worn for sure.

However, this is the screw I was talking about that should allow you some adjustment as to the clamping pressure.

If you loosen the jam nut and thread that screw in a little further, it should relieve some of the pressure. As the brass wears, you may find that you have to move the cam a little further to lock it. Then you can back that screw out a little bit to account for the wear to the brass.
For reference, this is about the position your cam should be in when the fence is locked tight. That's the peak of the cam profile. If you can't rotate it pretty close to that position, then it is possible that vibration from the saw and pressure applied to the fence are causing it to loosen up a bit.

Hope that helps!

Thanks for your help Ken. Looks like my locking system is very similar, it appears that I may not have the ability to adjust the tension.

Here is a look at the cam, the machining looks a bit sloppy.

True except I think he needs the opposite
Sounds to me like there needs to be a little MORE gap between the rail and the cam. Or a little less brass…
This is fence on the rail handle down to where it begins to engage the brass pressure plate.

Now this is fence off the rail and cam fully engaging the brass plate.

That seems to be a fairly good difference.
