Thanks everyone for the advice. I have found a couple more writings on the net and read what info is in all of the GS Kinks. I have a couple of pull-off Turk '38 barrels I will "practice on" (without a humidity box) with Pilkington's from
Brownells before trying on any of my barreled receivers. 50$ for the solution and a carding wheel should give me some idea if I have what it takes to blue my own creations, or should send them to someone who can do them justice. Just the thought of building a rifle from start to finish...
