Since we've had the old Frantom 18" saw, the split nut kept loosening up on the right side. I would loosen the nut on the back side and re-tighten the bolt, but after a while it would need to be done again.
While doing a cleanout I decided to try to figure out why. Took the nut off the back side - it was partially stripped. Suspecting the bolt thread might also be damaged I backed it out and found it was damaged about three turns down. That's why the nut seemed to snug up okay against the little "star" type lock washer. The nut was going on far enough to look and feel tight, but it was only tightening against that bad thread on the bolt.
Well, God bless Fran and Tom because the same type bolt holds the release handle on. I swapped the good one from the handle for the bad one from the split nut, then fixed the bad one and used it in the handle. Split nut engages much better now.
It causes Robin's eyebrows to rise up her forehead sometimes when I do it, but sometimes it's good to dismantle things.

Right on. Most problems don't need an owner's manual, or even an engineer --- just some patience, common sense, and occasionally an improvised part replacement. The feed mechanism on a slab saw is its heart and soul. And yours had new life. Adelante.
