I have an old table saw that came with round guide rails for the fence. The fence is out of square and i can apply pressure in the direction i know its out when i clamp it to get it to about square. There is what i think an adjustment knob that is missing a piece or something like that. The knob mechanism isn’t threaded into anything and has a splined end with nothing engaging when you turn. This has me confused as to how it would function. It also seems difficult to remove.

I was wondering if anyone had any information on this in particular style of guide rail or a fix to this?

Make and model and some photos would be very helpful.

Sounds like it is missing a pinion gear. It would be press fitted onto the splined end of the knob after passing through the fence casting. The tube would have teeth cut into it’s underside to mesh with the pinion gear.

Look for two set screws perpendicular to the fence. Adjustable and repeatable when properly set.

Right after i read MrRon, i checked after work and thats exactly what that was for. I felt a too sheepish to reply afterwards lol. I will check bgood for the two set screws. I know there are two on the topside of the fence that seem to have some adjustment but not fine. Thanks for the help guys
