The "no grinding" on the cage is a bit difficult in the real world.
What if you run out of gas mid pass or have a blast of wind interrupting shielding gas and get cupcakes for a small area. Since you can't grind, how do you fix that? Glob more material over the top? Take both bars out and start over? Neither of those are acceptable solutions.
I grind that stuff out and start over. Don't use a 7" grinder to do it! :)
