[QUOTE="grit, post: 641805, member: 4112"] Timing is next. The first photo is where the brake started. I view the brake and barrel as a clock face. The black line on the barrel is top dead center. The line is at 12:00. The brake is at 10:30. I divide one by the thread pitch. In this case, twenty eight threads per inch. This gives me .0357 per revolution. I divide this by twelve to get my clock face (.0029 per twelfth). I now multiply by 1.5 to get the brake to top dead center. I take .0044 off the barrel shoulder. In practice, I would take .003, test fit, and approach the final cut carefully. The brake has been timed in the second photo. [/QUOTE]
