Yep. Nothing wrong with blind rivets as long as they are used within
their design spec. If the ID is 2 inches and there are  14 of them
with a shear load of 200 pounds apiece that is a torque capability
of 2800 inch pounds or 233 foot pounds.


That shaft may also be bonded in there with epoxy as well.
If the ID is 2 inches and the bond area is two inches long that
would give a torque of 37,680 inch pounds by itself or 3140 ft pounds
assuming the epoxy had a typical shear strength of 3000 psi.

Those are philips head screws, not blind rivits.

Here is a times two blow up. Sure look like blind rivets to me.

We can settle it by asking Charlie but I'll take all comers on a $500 bet

Must be nice to be rich :-)

I have already sent everything to Charley including this message.
