FWIW:I converted the JPEG to a 8 bit gray TIF; imported into AutoCAD R14; scaled it so the big end was 28 cm. To an arbitrary level of accuracy, since these are old eyeballs.:1st Flange to 2nd flange: 3.0214284 cm2nd flange to Cylinder 16.59242861 cmCylinder: 13.5771431 cmDiameter of big end: 28 cmDiameter of cylinder: 17.2052288 cmNuts to you all.
"Still struggling to see how the momentum conservation would propagate to rest of cosmos in some "photon Unruh" generated perturbation, like pushing on the walls of its own universe or pushing on one's own acceleration. Surely this costs some energy, how can this energy be less than c*acquired_momentum or else borrowed from some potential, that is, communicated to the outside ?"

As I have said, a HUGE "I Believe Button" was pressed on this assumption. I provided data to show how how conservation of momentum inside the unit doesn't amount to a conservation outside.The unit still must experience a force from outside in order to move.http://gr.physics.ncsu.edu/files/babson_ajp_77_826_09.pdf page 2http://arxiv.org/ftp/arxiv/papers/1012/1012.5264.pdf page 2It isn't enough to just say that momentum was conserved and therefore it just moves, because it just does. That ignores hundreds of years of established science.
Another way to get at the length of the cavity is to look at the half wavelength multiples for resonance. But the wavelength is so short that it is not very helpful. Knowing the length and the wall taper (=.53) will give the small end diameter. I assume that the cone extends inside the cylinder some unknown distance.lamda n 2d=n*Lamda d, m0.12236 1 0.122364269 0.0612 0.12236 2 0.244728537 0.1224 0.12236 3 0.367092806 0.1835 0.12236 4 0.489457074 0.2447 0.12236 5 0.611821343 0.3059 0.12236 6 0.734185611 0.3671 0.12236 7 0.85654988 0.4283 I think we've had guesses for all of those values of n, except perhaps n=4. But maybe n = 3, as it does for Brady's device.
Well I've been busy as heck over the last few days getting ready for a board.

Yes, it would help if you can attach a file that people without AutoCad can open. I tried to open your dxf file with Mathematica and this is what I got:

Nicely done!
