Yah..it's surface tension..no doubt about it...dry wood, polymerized oil, and delrin are all more hydrophobic than a "damp" surface.........water molecules like to follow each other....a quick wipe w/ a bit of whiskey will straighten it right out !

Ha. Whatever the physics I thing Jack and I were agreeing that despite the 'loose coupling' there are several mechanisms for sensory feedback through the mouth and lips. Yup! Had a friend who was a pneumatic instrument engineer......was always amazed at what he could measure through a hole in a pla...

Acoustic streaming maybe ? (just found out about that by Googling) By turbulence I meant whatever it is that makes the rushing sound (in the absence of a flute) and is felt by the lips. The 'trying to whistle but can't get a sound out' noise. I think of Acoustic streaming as the gas flow response t...

Yes, that's the first two....I think you are thinking of the venturi (Bernulli) effect where the drop in pressure is a measure of flow..................

The third I had in mind was radiation pressure (the acoustic version)

I'm getting confused. Doug's OP was about back pressure. Are you saying that that is not at all related to DC flow ? Possibly getting my sciences mixed up but I think the term 'pressure' has different shades of meaning between fluid dynamics (? DC) and acoustics (? AC ). Yes, you have static pressu...

Oh! You've seen my M&E !

"..if the demand is there" is the key phrase... The rule of thumb hereabouts for us small shop people is if you get to keep 10% of gross sales ...your doing about right.....(and your investment is about twice annual sales........Gulp!) Maybe I could convince you to take up sputtering as a ...

Personal 2 cents on bending ? (maby Tal will weigh in here ?)....blowing harder and/or flatter across the head will tend to sharpen....softer and/or down into the head will flatten....when setting the tuning slide cold I use G and see 20 cents sharp and 30 cents flat and about +/-25 cents as it warm...

Both AOL (www.aol.com) and Firefox (www.firefox.com) worked....when used as browser.....then went to the flute forum and used your link, then selected the video.....at first I thought it wasn't working...took a while to set itself up even on broadband connection......

I can get it thru the AOL site......

Well, ya...the "average" flow spirals a bit and flows down the tube.....while the "dynamic" flow (or sound pressure/flow wave) bounces back and forth. The "average" flow is one of the things that can be used to flatten the pitch. PS: this is one way we used to make acou...

Still a bit OT, but my Gallagher Pratten set is on the way back from John....just got the notice.. YIPPEE ! :party: :party: :party: And, our own Frank Claudy recently got his much-awaited Rudall...I don't think he'll mind the quote from woodenflute... After a playing lifetime with old restored conce...

You can also get shellac dissolved in alcohol.....if your not allergic to alcohol this might work. You can let it stand a bit to thicken to any desired consistancy

That certainly fits the description...the older one was definitely turned from rod stock and the other has a molded exterior...and they play exactly alike !
