I decided not to decide yet. Instead of working on the inside of the tunnel I decided that I needed to fix a bunch of welding on the outside of the tunnel.
I went over all of the sloppy MIG and cleaned it up a lot.

Here the welder missed half a weld completely. Look where I circled the open joint. There are big pits where I showed the arrows.

I didn’t grind anymore on this. Basically I used the TIG torch to level everything out and blend it in. I had to go back and purge some spots of crap stuck in the weld.
