Hi all,

Just for fun, I put a web site with pictures of a rough trial vertical using
hard drive
hole inner surface disks with a 1/4" rod as the pivot.  The "base" layout is
roughly
similar to that of the Georgia Tech vertical; which does not use a mast.
The
perforated steel tubing (Ace Hardware) helped make it easy to construct.  I
have
not extensively "played" with it, so the period is only a fraction over 1
second.

Perhaps....the main points of it all, are the HD disks and the rolling rod
as the
pivot; and the extreme ease of assembly with the Ace Hardware perforated
steel
tubing, that served as the "base plate", that was utilized.
