Eureka, with an oops

OK, so instead of ten days we have a post only an hour later. This is strange. I just thought I'd share. I figured out that the compression/expansion ratio of the bellows and the main cavity are not the same. Not like it ever freakin' mattered before today. But that is why air keeps trying to go around the bottom of the guide and gets drawn into the damper. Go figure. Anyway, understanding the problem is half the battle. The solution will follow. I guess I'll stay up late and design the solution so I can stop the bleeding in China.
