This is the source of all my angst a month or so ago about pistons.

It seems to work -- I haven't fully broken it in yet, so I may yet
discover that the aluminum inner piston swells the assembly and makes
it jam -- but I'm so pleased at how well this fits and runs at the
moment, I don't think I'll mind all that much.
