We sometimes need comic relief from our labors. Well...a tuning lever is discussed, so maybe it's not totally off topic. 

I dropped my lever today on a carpeted floor. It made an obvious tone of A5, but maybe about 10-15 cents sharp of standard pitch.

My Fujan is 17" long with the straight end handle. It didn't make any musical tone when the end was removed.

If anyone wants to send me funding money, I'll study this in depth on other hollow-tube levers. It's an area in which there is an obvious dearth of knowledge.

John,

Yes, tuning the tuning hammer is extremely important. I tuned my Fujan to 440hz by adding lead to the ball end. Now I don't need a fork or a tone generator or anything else to get my starting pitch. I just drop my hammer on the floor to generate A-440 and away I go.

You must be fast! That tone dies away quickly. Or do you remember the pitch, pick up the lever, then tune from memory? Lol

I don't understand how a carbon fiber tube could ring like that. 

I have a very special set of forks. The one on the left is about E5, next is F5 and then F#5. 

( I apologize for the size. Uploading the video is already hard enough.)

I like those forks!

It's probably the metal in the head or the end and not the carbon fiber. Although the CF contributes to the tone from the tube. I guess anyway. I need funding to discover these secrets. Haha.

Geoff,

Lol!   You really eat pitch!

John,

I think it's the air molecules sealed inside that has taken on the physical characteristics of the carbon fiber, resulting in a space/time continuum setting up the resonant frequency of the column. One must be "as one" with it to experience the full effect. When my hammer bounces off the floor I quickly grab it in mid air and the vibrations are transferred to my skeletal structure allowing me time to set the pitch. If I'm really "on my game" I can get the whole piano to set in motion at that frequency.  It's a trip...!
