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?

Maybe this was a private email that escaped onto the newsgroup, but I
suggest the torgue should be proportional to diamenter; i.e., the 24"
drum torque should be 475 lb-ft.
