So who here has tried to make a homemade wind tunnel to test wings? My first attempt.

Here: https://www.frh.utn.edu.ar/media/empres ... ytunel.pdf you can see Tunnel number 2 is quite similar to what you are thinking.
It's in Spanish, but you can do a decent automated translation.
I was involved in the construction of that tunnel some 30 years ago...

It has a 3 DoF scale to measure lift, drag and moment

Thank you when I get to my laptop I’ll get a translation.

So given this thing is pushing some air I don’t think straws will cut it to straighten out the airflow, they’ll blow right out.

Any other ideas for making a honey comb?

sorry, no

but if you look in the 158 page pdf linked in my post in the Last & Best Piston Engined Fighter thread you can find ....
nice diagrams showing the workings of an old-school WTB (wind tunnel balance)
