I've posted this up on FPN too, its a bit of a weird one but I hope someone can help shed light on this.
My latest 51 vac is ready for reassembly, I'm itching to start using it after all the cleaning, polishing, and painting, but this clutch ring is making me wary!
Side A has a smooth inward slope after the hood/barrel mating surface. I've seen plenty of these.
Side B has a raised lip on the inner circumference of the mating surface, which is giving me pause. Won't that dig into the lucite? Side B also has an internal groove just after the mating surface. I've seen one other clutch ring with such an internal groove, but never a lip on the mating surface.
Why are the two sides different? Should I smooth out the lip, or leave it alone - does it have a function?
