As witnessed by some ijits rolling a 10.5" reel with 1/2" Ampex 456 audio tape down a road on a hill here a couple of weeks ago. It apparently took them two tries to fully unload the 2500' reel. It took me 3 days to collect and discard all of the tape, since nobody else wanted to. Still have the reel--and yes, the hub is smaller than the computer variety reel. --Chuck
