Haven't gotten back into the shop yet, but I fiddled with some related 3D models a bit
(click pic for full size)

This one is a cleaned up, up-detailed, and smoother model of the Control Module for the model's braces and sheets and the measured drawing it came from. Before 3D printing, I used my modeling software to model parts like this to check for size and fit, clearances, etc. In this case it was another attempt to explain how
Constellation's braces and sheets are handled, though there are still some folks that can't wrap their heads around it.

When I was figuring out a way to move, launch, and retrieve the model I played with ideas in the 3D modeling software. This led to about as simple a concept as probably be done, all without cutting any of the steel bed-frame rails that turned out to be really tough stuff to cut.

This is how the cart actually turned out, but I dressed up the model a bit with real spoked wheels (which I just noticed has too many spokes compared to the real thing), and a basic rig in the ship.
I've been asked to bring the model to an event at Fort Howard Maryland May 28th, I'm told it's an instruction event for maritime reenactors that'll be open to the public. The model will be jury-rigged yet again, but she should appear a bit farther along than the last time she was out.
My focus now will be installing those pin-rails and having things done that will be hard to get at when rigging commences in earnest.
