This was my solution. It's just a 3/8" O.D. tubing-bender spring from the hardware store, used to bend 3/8" copper tubing (the O.D. of the spring is actually about 1/2"). I drilled 9/16" holes so it can move freely & I'll "pin" one end in the hatch & let the other side float so it can move freely when the hatch opens & closes. I'm still going to tape up the wires where they run through the springs, to prevent any chafing & rubbing of the insulation, but it should work OK. If it doesn't, I'll post it in my build log & show another solution. The springs are very flexible & "soft" considering they're made from a tough, hardened steel. The amount of flex is actually very small.
I just never cared for the look of wires hanging out of the hatch and having that loop in the galley. This will look better, but it's a bit of a bother if I ever need to remove the hatch once it's installed for good. It can be done, but more trouble than a simple connector plug to break & just slide out the hatch if it needs work. The inner skin of my hatch will be removable in case I need to access things. As usual, everything's a compromise....
