Interesting! What's the final product supposed to do?
I'm not a complete idiot, some parts are still missing! :D

A rotor valve superbone is the plan.

That's a Bach valve in the middle and the one on the right looks like a Benge, Conn or King (Some type of 1990s UMI rotor). What's the valve on the left?

Yikes....did you chop off the port tubing and attach a new piece of tubing to the left rotor at a different angle? Dangerous move. Usually, the port tubes sustain a lot of stress. Thus, the reason why they are brazed instead of soft soldered and many models have thicker gauge metal in that area to resist bending/twisting. Be careful with how you brace that area. Any bending of the port could possibly make the rotor bind.

The valves are Eastman, Bach, and King. All three had various damage to the rotor knuckles. I cut nothing, I just Silver soldered on extra brass tubing as patches. My goal is to utilize junk from my parts bin to build a fun project. If it fails, oh well.

Valves 1 and 3 are plumbed... still working on two. I made them both a bit long so I can cut them down to correct tuning later.

Yes. Second valve section in place. A bit hacked together but it works. I’ve purposely cut all of the valve tubing a bit long so I can cut it down a bit later if I need to.
