My mistake.

I should have made it clear that the metal sink strainer already
came with its own shoulder bushing, so I already used a shoulder
bushing at the top of the plastic tailpipe.

The elbow came with another shoulder bushing, and only one
beveled bushing.

My dilemma was that I was essentially missing a beveled bushing,
but, if I followed the instructions, the entire pipe kept falling
apart in my hands.

So, there's something very wrong with this picture.

I just don't know how those instructions could possibly have been
followed by anyone.
