Tom,

The nuts I added were inspired by Sven Peter's post #20211 back on feb
13. (Thanks Sven !!) My variation has the two halves of the nut scissoring
in order to reduce the overall legnth and preserve travel. The nuts in the
photo are a previous attempt with two full nuts with a spring between; I
replaced with good reason. If (when) I do them again I'll go with something
a lot closer to Sven's original idea.
