I am not a professional gunsmith. I’m just a home hobbyist. Do your own research before doing any gunsmithing.

Good Work
Dude it only takes a few drops of loctite at the beginning of the treads and it will work up the treads as you thread on the barrel extension until seated then unthread it 360* to put the loctite on the treads equally then torque.
Next time I suggest you to make a wooden barrel clamp and use rosin between clamp and the barrel in a vise. Also make a bit different barrel extension clamp with a 1/2" square hole, so you can use a torque wrench to get it exactly right.
