Hi Folks,  Sorry about the drawing I will repost it,  including the left =
hand side which got cut off...I will also try to clean it up a bit.    =
And  more pictures.   This is just an idea sketch.

We all learn things which are undeniable truths.....One for me is " I =
must always make something three times to get it right"   Maybe that's =
were they get "the third times a charm"

Anyhow,  I would like to make another,  so if someone is interested in =
this concept, let me know and maybe I can help with some of the parts.  =
If someone has limited tools etc.

Paul C. suggested I use two ring magnets, one entering the top of the =
coil, and the other exiting the bottom of the coil.
I started with one magnet 1/2 (deep inside the coil), but I did not like =
the results.  I then moved the magnet to the top of the coil, just =
entering, that worked better.   I then added another magnet, two =
together,  1 and 1/2 magnets inside the top of the coil.   This worked =
well.    To try Paul's idea,  I would just need to open it up and move =
the spacing nuts and magnets.

To many details for this email, but its basically simple.   A 12" brass =
threaded rod hangs inside the two tees, on which are brass spacing nuts, =
and three ring magnets.  Two for the coil and one for the damper.

Another thing I would maybe do different is to use the 3" black ABS?  =
pipe and tees, as they are thicker wall and straighter.

With the rod+magnets+nuts there was no more room for a mass.  I tried =
addition mass and it pulled the spring too long.  I wanted to limit the =
total height to 7', but cut it down to 5'....I think at 7' the period =
was 2.4, and at 5' it was 2.2?

Thanks, Ted     So give me a little time and check the site =
