Thanks, Collin.
I'll keep that in mind if I should decide to take up the task one day.
But, based on what I've read so far, I should probably leave things well
enough alone until the day I'm swimming in A 50/1.7's and don't mind
losing one or two.

I've repaired a number of the A50/1.7 lenses.
The most common issue was the leaf spring being
separated from the body because of the plastic
aperture ring.
Keeping track of that detente bearing
was sometimes difficult. In the end, the
best way that I found was to just smear
some of the lens lubricant (grease) over it.
That holds it in place nicely, since it is
so small (1mm?).
You can always call Pentax Parts and order
a little bag of a dozen, or find a local
industrial supply and buy a bunch.
They are also steel, so I always kept a magnet
near the lens. It proved helpful quite often.
