Excessive extension tube stickiness

I have a 20" dob with a Starlight Feather Touch focuser. Nice piece of work. However, I bought a couple of extension tubes from Orion so I could get some of my oculars to come to focus, and they don't fit! I mean, they're the right size, but a shade too much in diameter. They would fit only if I want to really shove them into the focuser with ALOT of force - which I don't want to do!

Any advice or experience with Orion vs., say Lumicon extension tubes?
