Hi Scott - well the JB-Weld got me thinking, thinking right back to some of the suggestions I got when I first posted that the original one was worn. Your college exploits got me researching JB-Weld and that research helped me realize that the earlier suggestions to fill in the wear with JB-Weld would probably work just fine.
Cleaning and scuffing the inside where the ridge / wear spot is;
Mixing the JB-Weld;
It is still has some self-leveling to go here, but starting to take shape. Will need some clean up with a Dremel for sure, but not looking too bad...
We'll see how it comes out, but figured it was worth a shot. I will let you know what I get quoted for the weld repair to the one in the pictures from earlier in the thread.
