Of couse Jim understands perfectly well he is talking about the
saddle. Here's what kicked off the latest digression:

i'm aware of that design. and it doesn't have the immediate "dump"
fail
mode of which jobst accuses it since the post head and the bottom of
the
cradle are in compression. furthermore, the design which jobst holds
up
as "superior" really isn't because one bolt at either end of a two-
bolt
clamp is incapable of preventing tipping, so you're pretty much in
the
same position.
-----------------------------

But since he doesn't like to admit errors and correct them, he would
rather obfuscate them.

Oh and a two bolt design will equalize clamp pressure so long as
everthing can slide around.
