Aperture Ring Stuck

I am new to the forum and have been lurking for a couple of weeks, learning a great deal from the many posts.

Here is my problem: Friday the 13th struck me... I was using my SMC Takumar 50mm f1.4 lens on my K20D and somehow didn't manage to lock the lens in. To make a long story short, the lens fell onto a carpeted floor from a seated height and the apparent damage is a stuck aperture ring.

I searched the lens discussion database and found one thread that mentioned a misaligned aperture blade notch (post by ftpaddict). I also note from the discussion threads that there are no repair facilities available to determine if this lens is salvageable.

Does anyone know what has to be done to free up the aperture ring (stuck on f2)?

Thanks, ovim, for the link to the instructions for opening the lens. I'll study them and determine if I am willing/able to make an attempt.
