Hi PSN
Folks.........hope this is the correct address.

 

I have finished a Mini Lehman, and have
picts.   This is an amateur attempt to make a small Lehman,
enclosed/covered,  using a small fish aquarium, and has an 11 second
period.   I learn a lot by doing, and Happy to share what I
have.

 

If you are interest in pictures, and other
information let me know.  I will be posting the data files on psn as
TCIDM.   I know many of you are interested in discussing
developments so happy to do so on PSN,  and email.   
No great revelations' to discuss or share, it is just a very small Lehman
8.5"x 12.5"x18.5"  but it seems to be stable and
quiet.

 

Cheers, Ted
