Worked out some more details of how to do catenary on a1x12 x 8ft display shelf and test track thing while in waiting room during Kathy’s knee replacement surgery.
You’d have thought they’d never seen someone layout a sketchbook and scale and design model train parts in surgery waiting before.

Sure beats reading year old magazines

When my wife was having my little guy I wanted to set a circle of track around her bed. That didnt go over well LOL

Forrest, my SWMBO is up for the same surgery. How’d it turn out with Kathy?
Very well.
Only complaint I have is that they wouldn’t let me help.
Funny how Kathy doesn’t share that complaint.
She had other knee done last year.
As long as she practices FOLLOW THE DIRECTIONS, she’ll do fine.
With the understanding that it WILL hurt for a time.
Granted there are always risks of complications and infection when slicing the body open and kitbashing the bones.
Get up and move like they tell you to, there’s good reason for that.
