Prop Shaft

[2manymustangs]

I spent several hours at the drags at Firebird 2 weeks ago benchracing with Wayne Mettler in Don Bausher's pit and the subject of prop shafts came up. Either Scott Owens or Tim at Lenco has a shaft material that according to them puts A22 and Inconel in the trash can. I will see Wayne this weekend at the drags and get more info. If we can stop breaking shafts the weakest link will then be the prop!!!!!

This is the question I have been wondering about through all of these discussions (here and on PB)... If we can make axles that can last pass after pass in a pro mod OR monster trucks turning earth mover tires or a TF dragster/funny car, why can't we improve on the material that is used... I do get the need for a material that is corrosion resistant, could some kind of nitride or iridite 14-2 or nickel plating could be used, maybe, if the NEW material was carbon steel and NOT stainless???

I have thought the same thing. Not to mention off road torsion bars being cycled like crazy, in 2 directions. 300M seems to be the material of choice for shafts that are subjected to heavy cycling.
With the rudder, turn fins and props all made of carbon steel, I don't really see the "requirement" for a corrosion resistant material, specially on something that cycles thru a prop shaft as fast as a TFH.

I don't think I would want to run a carbon steel shaft on the GN, but it would not surprise me one bit if the stuff Wayne is referring to is a carbon steel.
