Saw the board in half along the axis of rotation. Using a 1/4 core box
bit in your router table, route into the sawn edge. Edge-glue the
pieces back together.

You might consider running metal tubing while gluing back together.
Glue with epoxy.

But how would I make a hole that is 5 inches long? And would MDF be
strong enough for that?

Thanks.

As I mentioned the axis will be at one end of the board, so that wouldn't work.

I have no idea what that is.

Aren't there "cups" that one can place inside of pre-drilled holes for
something like this project?

Thanks.

There are pieces that fit like a 'U' shape over the edge, with a tongue
that hangs out. then you bolt _through_ the MDF(or whatever) from one
side to the other. Lock-washer/ LOC-TITE / whatever, to keep the bolts
from working loose.

I would be confident in making a hole through the 5" length. I would
use a drill press with a milling cutter. I could cut more than 3" from
either end and the holes would align very accurately. The milling
cutter will have less wander than a conventional drill bit. Most of the
metal mill bits are short but the ones for wood are long enough.
