 Seems to me the easiest solution without having to go through a lot of monkey motion or cobbing something together is to buy a real prop wrench.  You don't have to pay $200 for one either.   Avery has em and the design readily adapts to my digital torque wrench.   Beware the chrome flavored Hartzel prop wrench  offered by ATS.  My (returned) example broke way before minimum torque specs were met. I suspect it may have been due to an improper or omitted heat treatment.

 ------- the problem is these are for 1/2 inch drives and not 3/8.
 I'll try the stub wrench with a bolt in the closed end method.
