Its a forum, I've been here for years. Your opinion is as viable as mine.
IMO: Your time + cost to do what you explained in your post a couple pages ago to save a T3x pencil barrel, even if you're somehow finding buyers that are willing to pay 3x the value for the barrel (hell, almost every CTR take-off barrel I've seen has sold for 125-150) isn't worth it versus bringing it to a smith and having a relief cut made. Especially considering you could mar the action as that wheeler wrench, while usable, is pretty cheap and not exactly high quality.
Thats my opinion as to what someone in that situation should do, which is just as viable as yours and others may find useful.
