Good job! I too had a similar situation with one that was used for silhouette shooting (hot loads) .357 maxim. Bought from a coworker at a silly price and fixed and updated with the same parts and tool you mention as well. Then sold for a 3X profit. I posted this on the DW site as well a couple of years ago.
This was a 8″ version with a very stripped barrel nut. The gun had not been fired in over 10 years, nor cleaned. I read the posted barrel removal closely and tried to make it a better mousetrap. I’m an aerospace engineer and not fond of vise grips on all thread so this is what I did.
Mcmaster Carr parts: One 9″ long 5/16-18 steel bolt #91257A122, bag of small diameter flat washers #95229A460, and one bag of small hex nuts #94191A200. Total cost $21.72.
I figured using a hex nut in the cylinder area would allow me to add torque during the loosening attempt. Not a lot of wrench clearance. No go. To tight. Then I added another nut (jam) and tightened everything as much as I could using a soft jaw vise. Next I heated the frame carefully with a heat gun until I saw some bubbling around the threads in the cylinder area. Using all my hand strength, no go. So I said a few choice words and brought out the 3/8 butterfly air impact wrench to put on the hex head on the end of the barrel. Just hit it a little bit and boom that bad boy came right off. After pulling the barrel from the shroud that barrel nut came right off by hand. Go figure.
