I'm still not seeing a problem.
We easily hang 150lbs off a similar hook (only with plastic spacers and the official screw of all right-thinking FIRSTers the 10-24). Our last one is the axle for a pulley with a loop of
1.9mm Spectra from Spearit.com all is well.
The only "tricks" are just to be sure that the axle gets loaded in double shear not in bending because over an inch span the stress can get a bit higher than I'd like and make sure to guide the cable to the middle so that one side doesn't take all the load over the other.
If those are the hardest issues I have to solve in FIRST, I'd be in good shape...

Force yourself now, today, to learn one new thing each day. When you lay down on your fluffy pillow at night, before you say your prayers, ask yourself if you have learned anything new. If the answer is "NO" then you better get up and find something. - Al Skierkiewicz [more]
