Here's the second stage of the project. It has been slow going, as I can't really do anything noisy or break out the power tools while the girls are home. I pinned down the plates, finished plating the main chamber assembly, and added the main chamber and a couple of little embellishments to keep stress off the chamber parts while the gun is being handled.
The next step is going to be to assemble and install the forward chambers, and then comes the trigger plate, trigger and muzzle. I still haven't picked a muzzle, but I think once the forward chambers are in one of the few I've started will suggest itself.
The trigger guard remains the biggest challenge, aside from finding time to work on her.
