Is quilling the horn at all possible?
..........Quilling or paper filigree is an art form that involves the use of strips of paper that are rolled, shaped, and glued together to create decorative designs. The paper is rolled, looped, curled, twisted and otherwise manipulated to create shapes which make up designs to decorate greetings cards, pictures, boxes, eggs, and to make models, jewellery, mobiles etc. The most popular and versatile technique is that of rolling. The paper strip is rolled in fingers or using a tool. The coil is then released and then glued at the tip and then shaped. These shaped coils are arranged to form flowers, leaves, and various ornamental patterns [SUP][1][/SUP]
Ok, I have been doing the Trains thing for over 60 years, what the heck is Quilling? Ok folks I have asked what all of you were afraid to ask!

Anything with an analog valve really, supposedly there are some new equipment in which a button has a degree of quilling capacity. Whether or not this is built in or incidental, I am not sure.Isn't this achieved on early locomotives by the pull lanyard? By the way, the demo seems as if the horns are are out of tune.

Blowing pressure – Frequency increases with blowing pressure,[SUP][30][/SUP] which determines gas volume flow through the whistle, allowing a locomotive engineer to play a whistle like a musical instrument, using the valve to vary the flow of steam. The term for this was “quilling.” An experiment with a short plain whistle reported in 1883 showed that incrementally increasing steam pressure drove the whistle from E to D-flat, a 68 percent increase in frequency.

I suppose this is therefore considered applicable to horns as well.
Interesting...
But... going from E to D-flat is a 68% decrease in frequency not an increase. A D-flat (or C-sharp) is 1-1/2 semi-tones below the E-natural.
Probably wondering... I play the piano and have tuned other keyboard instruments.

Hehe, there is your reason.... I play instruments too. I figured It was best not to play percentage wizard and try to edit it, I am 90% sure that 67% of that number is pulled from 30% of that writer's bumm.![]()
it's down a few cents and it will cost me a lot more than that to tune it!![]()
