I see you are using two clamps to hold the fence in place ,they do work well but a pain to use.
Here's a tip,,,,,,
and a easy way to lock it down.
Put a slot in the fence base and one hole on the other end and use it as a Swing Fence, it's a easy way to lock it down and easy fix.
90% of the items you do on the router table will use the fence right next to the bit or to say right in front of the edge of the bit.
But you can still use the clamps when you put in a dado that's about 6" from the fence.
When you want to change the bit you just unscrew the one on the right and just unscrew the one on the left just a bit and swing it back out of the way,make the change and pull it back and lock it down.
You can make a stop block for the back side of the fence so you can get it right back to the same spot when using match set of router bits and the same bearing on the bit.
Right back to the zero point on the fence.
Or if you are poping the router table base out to change the bit like Bob & Rick do this also works great for that also,just slide the fence back and pop it out then pull back and lock it down all without any hand screw clamps
See small drawing below quick and easy one to install and cheap.
Just a Note about the Tee Nuts,,,I aways cut the sharp point off the tee nuts and glue them into place,this way they will not drop out of place and the ponts will not split the wood. (if I recall the bit size for the 5/16" tee nut is a " N " drill bit and must be right for the barrel size for the tee nut) you want it just slide in with out nailing it will a big hammer, just a small tap should do it.
Plus a snapshot or two on the fence I have on one of the router tables ,I use a snap pin on the right side of the fence, it's spring loaded and I just pull it up and turn it a 1/4 of a turn and it locks in place then I can just swing the fence out to the left side and do what I need to do then just pull it back and let the pin drop back into the hole, I also have two holes on the right side of the table top so I use the BIG bits like the 3 5/8" panel bits, the 2nd hole moves the fence back about 1 1/4" from center.
