If we can stop breaking shafts the weakest link will then be the prop!!!!!
    Hey Steve O, hope all is well with you sir...

    Did we learn anything about these new prop shafts, new material???

    Not yet, I've been too busy. I will get the info and am considering having a prop made with splines and no taper or keyway. Ron Hill says that would be no problem.

    I'm guessing that not ALOT of folks haven't taken apart a brush hog gear box/T-blade mount but many use a tapered spline. I can't imagine that a prop could see any worse shock loads than my brush hog has seen (that is 25 years old) and has NEVER has been apart... THe shock of hitting a big stump or a basketball sized rock that is hiding in the tall grass with a brush hog is enough to shake your teeth out at the roots, and yet it stays together (they do have a dry clutch disk coupling on the gearbox output but are usually very rusty/crusty/TIGHT)...

    Need to get the engineer from "Brush HOg" to do some moonlighting and tap into what he/they know... (fit/finish/clearances/material)

    I guess a taper/key design goes back a LONG LONG time to days where you wanted a shear to take place if there was too much force/shock/mud/rope/kelp/rocks impeding the prop...??? I dunno, just speculating...

    Keep in touch Steve O... I'm looking forward to a visit with your crew at Long Beach which is JUST around the corner sir... I'm sure I will be grilling something so look me up (on the dark side of the stadium)...
