"fixed"?
Hi Don,
Great stuff, as before. I am really enjoying this exploration and looking forward to reading more about your findings.
When you say that one version will have a "fixed" coupling spring, do you mean that it will be so stiff as to effectively be fixed? Part of me suspects that even a VERY stiff connection will transmit sufficient vibration that very closely regulated balances may be able to couple with each other. I guess your real world explorations will elucidate further.

Don, I'm following your post series with the natural curiosity to see all theories materialized, up and running. Thank you very much for sharing the "birth" of a very unusual movement since the initial steps. I have several questions that I'm putting on h...

Looking forward to the results of the two resulting springs. Non coupled and coupled. Reading this with great intrigue Don! Marvelous work, and difficult work!

...when I could absorb them in the manner such interesting and thoughtful work deserves. Being on holidays means I need to dig out the laptop to read them in detail. Thanks for this project, Don. Truly intriguing.

"nearly fixed" ?
Of course, John, but I think there will be more coupling through the air. I designed the balances very close together because I thought it looked better that way. I wasn't thinking of doing testing at the time. So it will not be possible to shield between...
