[CAUT] Moving wippen rail

[David Love]

I guess the bottom line is your bottom line.  If you shim the wippen rail
out and the UW and DW drop then what does it really matter whether the
explanation is vectors or leverage?  The issue is whether you can lower the
effective touchweight with this method.  Clearly you can.  While jack
alignment is obviously important there are tolerances in this area
especially since the jack/shank interface rotates through several degrees
anyway.  While it may not be the first choice for changing leverage, it can
be an effective way of reducing the touchweight, albeit minimally.  The
proof of the pudding is in the tasting.

I shimmed a rail out today and yes, the UW & DW dropped. I don't 
attribute it to
improving wippen ratio but vector alignment.  If I kept moving the rail back
I'm sure the numbers would degrade.
