Ok, thanks for everyones help. I think I figured it out and now it's shifting much better. However, still needs some tweaking. I measured the gap to the top of the FD and it's now 1.5mm approximately.

I loosened the shifting cable and measured the FD at 1.5 mm. Then set the limit screws. Once I attached the cable to the FD and tighten the tension bolt holding the cable it seems to have aligned the FD properly. At that point, making a minor adjustment to the limit screw with the cable now attacked seems to have done the trick.

The shifting cable seems to sit lateral to the bolt when I tighten it. I'll post pictures in the am. It appears the cable can slip out.

In the worst cases where the anchor won't hold the cable, you might have to do a little filing work ... or even use some shim material (washer or jb weld) to get good purchase.

Just don't use a wrench on the bolt. You don't want to strip it. I always use a socket driver with 5/16" socket.

@Cyclologist - On the arm under the washer of the fixing bolt, there should be a groove the cable "fits" into. It is nearly tangent to the threaded hole.

To me, it seems the derailleur is still further from the chain ring than it should be. If that works then ok , but I would be concerned about dropping the chain on fast shifts. I donít use a gage or measure the gap , just by eye. About the thickness of a nickel between the cage and the big ring, but with that small of a ring with a braze on mount, it may not be possible.

sorry for the dirty chain ring, I ride this bike a lot!

I'll look for that grove, as I was tightening the cable from the nipple I accidentally pulled out the nipple and frayed the cable.

I can see the gap is very close and the gap on my FD is much larger. If I go any lower the rear of the FD will hit the chain stay. But it seems to be shifting properly for now.

The pinch bolt assembly is designed to clamp onto an un-frayed cable.

Usually I can un-fray a cable by pinching it where it's still wound up and then twisting the cable between my fingers as the cable is withdrawn.
It helps that I'm stubborn!
