Machined from Billet Aircraft aluminum two up at a time, in our American made Fadal Machining center where we bore the holes to 30mm +.0014 / -0. When we machine the profiles of the ring we build in a .030 radius on all outside edges.
Next we machine a 45 degree bevel around the entire ring and clamp to match.
We clamp the pair on a 30mm mandrill with a 1/8 pin to locate the pair exactly together. Thread form the tap holes in the ring thread forming is 40% stronger than cut threads.
The rings are serial engraved before they are separated one ring and cap has a period in front of the number so the caps match exactly. .0040 and 0040
The cross bolt is made from Chrome Molly steel in our turning centers, roll threaded and heat treated in house and blued locally.
The ring nut is beveled on both ends, an inset washer is used to keep nut from scoring the finish on the clamp.
The threads are roll formed for strength, fit (class 2a) and finish. The clamp is machined from billet. Complete with radius and bevels and anodized to match Rings are tumbled in house.
