I get a lower number. Just estimating things here but came up with the following:

6 lb lead hammer = 2.72 kg
Moving at 11 m/s (about 25 mph)
Decel time hitting spinner = 0.01 sec (10 msec). Just a guess here
Decel therefore equals 1100 m/second squared
Force = just under 3000 Newton’s = 674 lbF
Spinner radius of about 6 inches means a torque of 335 lb-ft
