Vertical Hitch Pins, was [CAUT] duplex position

[Richard Brekne]

Hi William

Perhaps they can... then again Frank attests to at least a happenstance 
or two f this not being the case.  Not really the point tho.  Here the 
point is just making sure that the plate will behave nicely when put 
under a stress it wasn't designed for.  If one has checked this out and 
it becomes a known then I'd agree there is no problem structurally.  
Then we are just left with whether or not its a desirable or not... and 
that seems to go well over into a subjective realm as much as it goes 
anywhere else. 

I'm glad tho that caution is raised. Makes one think over what one is 
doing.  Grin... there is enough that can go wrong even in the best laid 
plans as it is eh ?  I can just see some poor sap showing a freshly 
rebuilt instrument to some critical customer just as the thing goes BANG 
:):) 

We dont see any of these vertical hitch pin solutions up here in 
anycase... and probably not much down on the continent... so its not 
really an issue here.  And as I said in my last... I'm not really sure I 
see the big deal one way or the other.  The slanted hitch pin and back 
scale in its multitude of variances works dandy enough. I suppose the 
well thought out vertical hitch pin system does as well.

Ya don't think Baldwin checked out plate stresses when deciding to 
introduce these vertical pins then ???

        Hi Ric,

        I think what you say makes sense, but I don't think it's safe to
        say that
        just because it's intuitive, a particular manufacturer took that
        step.  I'd
        think it would be just as easy to say that most if not all
        plates can easily
        withstand the pressures of vertical hitches with the strings
        "riding high."
        Maybe someone knows if this was really a design consideration at
        Baldwin.
        Del?
