One side is an angle solver, and the other is a circular slide rule to solve for time, distance, speed, and angles.

an other KM wizzwheel model?
Quote:
te adjunto enlace a foto de otro modelo de regla de cáculo circular de la KM, recién adquirida. ¿Tal vez pudieras contextualizarla en relación a tus fantásticas piezas? Carezco de manual relacionado. Mil gracias de antemano por tu ayuda. Subiré fotos más en detalle en cuanto saque tiempo http://ag727.vox.com/library/post/re...rpedoskm.html descripción: Manueller Torpedovorhaltrechner. Skalenscheibe aus weißem Kunststoff mit einer Plexiglasskala zur Einstellung und Ablesung von Lagen, Schneid und Vorhaltewinkel bzw. Schussrichtung. Hersteller "Dennert & Pape, HamburgAltona", Werk.Nr. "73988". Dazu der hölzerne Aufbewahrungskasten mit Firmenschildchen und Nummernschild "Mar.Nr. 2151. Kastengröße 28 x 35 x 12 cm. saludos Alejandro

OK, it looks like a standard circular slide rule with a couple of linear arms that pivot off a centrally pivoted arm. That could be kind of tricky to make out of cardstock and transparencies.
Perhaps an adaptation of it, simplifying those functions done by the arms, would be a better idea.

WizWheel files
Is there any chance of obtaining a vector graphic of these files I am getting them printed onto vinyl and stuck onto thin plastic and the print shop would prefer to work with vector format but can still do raster if thats all I can provide.
Thanks, spugnoid

Alex,
that's the german equivalent to the american BANJO, and you can find instructions for its use here: http://www.hnsa.org/doc/banjo/index.htm That was a typichal WW1 calculator, but in WW2 they were kept for backup purposes, in case the TDC broke Quote:
Only, it would be a large amount of work to create the templates , but not to later build it once you have them. Quote:

Welcome aboard, Spugnoid.
I don't have the answer you seek; but, one of these lads here is bound too. So stay tuned. Cheers,

Well, I've gone ahead and made vector files of the front side minus the transparencies so far. Now that I look at the backside it appears to be some kind of log scale. I'm just learning to use a vector program as I spend most of my design time in photoshop. So now I'm at a loss as to how to make Inkscape behave in such a way.
Oh well, the front side turned out quite well for my first foray into vector. spugnoid.

Ok, I'm wondering if someone can help me out here. I am trying to build the backside of the attack disk in vector but I am at a total loss of how to calculate the position of the ticks on the scales. I can plot a sine wave on paper but can't for the life of me figure out how to put the values on a wheel, i.e. right numbers at the right angles.
I have spent well over 2 hours on search engines and can point you to a dozen or more sites that have slide rules of all types and shapes for download, but no one discusses the math behind the scales. I'm sure that at least several people on this board can do this in their sleep and if you would care to slide (ooh! a pun!) a few formulas my way I would be grateful. I will be sure to post my files when finished. spugnoid.

If I understand you correctly spugnoid...then,
draw straight lines on an "x", "y" axis, let their intersection be called "o", using "o" as the center of a circle, construct a circle. draw parallel tangents from top and bottom of the circle. Within those parallel tangents, construct said sine wave. Now, from the center point of the circle draw a radius that would represent 0 deg. Let same radius represent 0 deg. of the sine wave. (drawn precisely between the parallel tangents). Now draw a 45 deg. angle from "o" of the circle to it's circumference; from this point on the circle's circumference, continue drawing this radius making it also parallel to the afore mentioned tangents. You will now note that where this line intersects the sine wave, will also be the 45 deg. mark on the sine wave. You are now free to continue drawing additional radii and their sinusoidal equivalents. Sorry that I don't have my scanner hooked up or I'd send you a pic.

i don't really know what vector is, but i've made some of these disks before for the Ujagd tools mod, and I used a spreadsheet to produce all the appropriate degree deflections for the required mathematical formula
