    Ok I've got a REALLY tough question for you guys now. How exactly do top-break revolver auto-ejectors work? I could really use some images or videos to help me understand the mechanism.

    BCCL great resource but I need to know how the parts interact to operate the auto-ejector

    There is a projection in the hinge (part of the ejector cam at the hinge's center), which engages the ejector strut, and then slips off, allowing a spring to return the ejector. Typically shaped like a hook. There are some photos here which the site doesn't allow me to copy.

    Maybe best to obtain one and disassemble the hinge (easily done) to see how it works. Some of them (Iver Johnson, H&R, etc.) are quite inexpensive.

    Same design and principle as the over & under or SxS shotgun ejectors.

    http://www.amazon.com/Smith-Wesson-Six-Guns-West/dp/1931464103 << "Smith and Wesson Six-Guns of the Old West" great book for anyone who loves the Schofield. Multiple exploded views, repair techniques, load data for the original Schofield cartridge, and some history.

    The extractor works fairly well as long as you don't try to extract them in an upward direction. gear goes along the drive, drive snaps down at the top. There is a stud on the hinge that can allow you to open the gun without engaging the extractor.

    Some people can snap the front half down energetically enough to cause all shells to fly out, Often trying to eject the shells at an upward angle can cause the extractor star to sneak past the top of the shells, and snap down on top of the rim, not hard to get them out, just a few wasted seconds getting the extractor's gears back down to the start point and raising it again.

    (if you need the visual, circular gear in the hinge end engages a Screw shaped, spring loaded rod under/inside the barrel, dropping it at the end of it's stroke. )

    Thank you all I think I may have figured out a solution for the project I'm working on.
