One new set of Newtone strings - .55 to .140 with hex cores. It feels tighter and better. To be honest, I think I am right on the edge of what will work with the lower strings (possibly over the edge) and it is going to need some very careful setting up. But I have started so I will finish, and I do love an adventure!
It will now be sent to a proper grown up to route a hole for the Delano pickup.
If I had one of those Shaper Origin DIY CNC doobries I would do it myself. But then I would have to send it to a grown up who could actually measure properly to tidy up my mess.
