Reducing the drum size has more effect on torque than I realized. My
spreadsheet shows 953 lb-ft for 48", 242 lb-ft for 36" and only 85 lb-ft for
24".

What do you think?

Something is wrong here.....you need to read your info or your
spreadsheet doesn't make any sense....!!!??? Torque measured where?
The drum diameter has nothing to do with the torque!!! Is this for
which drum application? Need more and correct info in order to give
you some numbers.
