I think we are chasing gnats here. The clamp behind the quadrant is minimally deformed(caused by over tightening), but is not contributing much to the 'problem'. It does explain the amount of rise above the infeed table when clamped. It can be corrected by judicious squeezing in a vise, but I would not do that unless it gets much worse.

However realize when loose the fence is free to seek a wide range of angular orientation. It is almost guaranteed to be different from clamped orientation.

It is difficult to determine from the pix if the fence is merely shifting horizontally of if it is also tilting.

I would get the 90° stop set then take another look at the lateral shift. I predict it may get smaller from appearances. BTW be sure to set the 90° stop with it clamped tight(lateral clamp). The fence can be loose to allow tweaking, but the final test is with both clamps tight.

In one of your pictures it appears the gorilla JPG mentions may have already been at work on your Jointer. Notice the gap pointed out by the arrow in the picture below. This is not currently a problem but may become one if overtightened repeatedly. Generally this type of overtightening strips out the threads in the Quadrant that hold the internal/external threaded sleeve that the bolt (fence lock) goes through and the nut (angle lock) is on.
As for the fence moving when locked down that is normal. When locking the Fence the Lock Bolt is pushed against the Fence Bar until the the "fingers" of the Quadrant are against the back side of the Fence Bar. This action causes the fence to move into alignment. This can be seen in the picture above. Only when rabbiting boards on the Jointer will this movement be critical. Again, not a problem but the measurement must be taken and readjusted if needed after locking the fence for rabbiting on the Jointer.

Thanks so much for your input
