has anyone ever tried this?

[Brian Doepke]

Yes,  I certainly think that is the conclusion I am getting to.  Although I
was only thinking of a jig to use for bass strings only...and having several
tuning pins at various distances from one hitch pin so that the loop can be
made at the absolute end of the wire.which will probably be cut off anyway
even if there was no pre-stretch.
 
Thanks for your insight.

The problem with any kind of jig that would pre-stretch a string is that
bass strings come in a variety of lengths. A string for the single strings
would be need a much longer distance from hitch pin to tuning pin than the
string up in the tenor section. The jig would have to come with a moveable
hitch pin. The other problem is when you turn it on the tuning pin, for an
upright it might not be a problem, but for a grand, you're going to have a
heck of a time putting that string through the agraff. 

Hanging a weight on the end of string might be the best solution, but in
order for it to be effective, you would need a weight of approximately 150 -
200 pounds. How are you going to attach that much weight to the end of a
string?

Sorry, Brian, but there is not easy solution. Sometimes we just have to do
what we have to do, and leave it that.

Brian, 
While I don't know if Mike Spaulding is 100% correct that "it's all in the
bends", but if you really wanted to pre-stretch the string your could take
some old pinblock(s), pound in a hitchpin, perhaps make some kind of bridge,
drive a tuning pin in an appropriate tuning pin hole, and pull it up to
tension. So .. if you really want to pre-stretch, make yourself a monochord.

Sorry for the confusion.

I still can't believe that someone has not discovered a way to "pre-stretch"
a new bass string.  Maybe something like hanging a weight on the end without
the loop?
