Since calculators have now diverged... figured I'd repost some of my iOS calculators, that I've made and used. They've been updated a bit... now you can either use the "USB to Wheel" measurement, or if you want to measure to the casing, FVB, etc., that is available in the app as "USB to Casing"... the calculators allow you to enter your own horizontal and vertical measurements, making it "less restricted". So, for example, it can be used if you build your own FVB, or use a different machine. (If you don't know what this means, stick to the "USB to Wheel"... then the h and v measurements are not relevant). Some suggested measurements are given in the app.

An Angle Calculator to set the USB height, that works in the Apple Numbers app...
https://www.dropbox.com/s/o43tsfj1kwzemu9/USB%20Angle%20Calc-Universal%20%28Public1.1%29.numbers?dl=0
(To install click "Direct Download" then "Copy to Numbers").
An Angle Calculator to set the USB height, that works in the GoCalc app...
https://www.dropbox.com/s/d2hah4c1krrlvgv/GoCalc2in1Calculator.xml?dl=0
(To install click "Download" save the file TO A SEPARATE COMPUTER or DEVICE, then follow the instructions in the GoCalc app to "Import Calculations"... do not "Restore Backup"). You can't (from what I can tell), download the file to the device that has the GoCalc app on it... it installs the calculators via WiFi. (This will actually install 2 calculators).
GoCalc app can be purchased thru the Apple Store (I have no affiliation)...

Just be advised... they don't come with any instructions... up to you to figure out how to install and use them... properly. ;)

Added 11/22/21: Links to "OpenAngleTool" created by Tormek forum member "freejack"
Open Angle Tool forum thread (https://forum.tormek.com/index.php?topic=4666.0)
Open Angle Tool Calculator (https://openangletool.github.io/)
This calculator works as a web app, and on both iOS and Android, can be saved to the homescreen and run as an app. It gives answers for both "Measuring to the Wheel" and "Measuring to the Machine", so can be used on any Tormek model, as well as similar type sharpeners.
All based on Dutchman's fine work (https://forum.tormek.com/index.php?topic=1849)!
Enjoy! :)

CB,
If I may put my 0.02$ in, the displayed USB Top to Wheel Distance is by 0.02 mm smaller than the exact value. ;)
It is of course fully negligible. The reason for it may be some rounding or number representation.

CB,
thank you very much indeed! :)

Quite a difference.
If you're an Apple Numbers user... here's what I call a "Visual Angle Calculator" for setting the USB height for knife sharpening, (same calculator, different perspective... maybe gives an idea of what's going on?) :) ...
(https://forum.tormek.com/index.php?action=dlattach;topic=4373.0;attach=4704)
... can be downloaded here: Visual Angle Calculator (https://www.dropbox.com/s/hj6xxs3jeqk6jm2/Visual%20Angle%20Calculator.numbers?dl=0)
Edit 4/25/22: Updated the link
Consider this the "iPad Version" of the above... ::)

i putt ur Data in my App and what comes out???
please don't get me wrong but that's exactly what I'm trying to explain to you but I've fallen on deaf ears so far :) if I want to use ur calculator I first have to take a course to understand everything. it could all be so simple :). so again you can shoot at sparrows with cannons or why simple if u can make it complicated. keep it simple is the goal. as you see on the result it really works.
with mine one sentence is enough to explain the whole thing i do not need a drawing and not almost a whole page to explain it :)

It's the same thing... just in picture form. ;)
Go hide the video you made on how to use your software (https://youtu.be/HKtMz4Q1dSM)... then see how many understand how to use it. ;D
why i post this????
the only reason..... and i think i understand a bit off this stuff
if i watch ur Picture i get confused :)
but i know u do a lot of work with it and i respect that a lot.

Ah I understand now.... yeah I can't argue that. It does look like a mess without having some idea of what's going on.
I think of this as more of a "visual guide" to how it works, if that makes sense. In reality, it probably does need a bit of explaining. It wouldn't take much, but you're right, at first glance it does look confusing.
Thanks!
p.s. Keep in mind... I still have the "simpler" options available... ;) (I think you called them "ugly"). :D
(https://forum.tormek.com/index.php?action=dlattach;topic=4373.0;attach=4576)
yes my dear i stick to it.....looks ugly and untidy :)
but, and you shouldn't ignore that.....it costs nothing :)

(Translation of "USB to machine" and "USB to wheel" provided by Google Translate... no idea if it's right.) :o
I will check.
But why needed :) the final result is the same

Many use the "USB to Wheel" measurement, for example those who use this Angle Tool (https://forum.tormek.com/index.php?topic=4170.0)... and they can't use the "USB to Machine" measurement.
It can also be used if you don't have the Horizontal and Vertical measurements available, or to check the accuracy, etc.

Hello,
nice visualization. Believe me or not, I have something similar on my TODO list (with very low priority) - I planned add text boxes to drawings in TormekCalc to make dimensions "live". Well, you were faster. ;)

IMHO, it can seems so, but practically
you have to enter the same values, independently on used calculator:
- Projection distance (Jig projection length)
- Wheel diameter
- Sharpening angle (Grinding angle)
and machine dependend constants (if you don't use default ones). The others are just advanced options and it depends on whether you use them or not.

The final result may not be the same, it depends on right values of horizontal/vertical constant. "USB Top to Wheel" dimension is always right (by design), if correct math is used.

I believe you. That's actually a better idea... just putting text boxes to show the changes in the diagram.
Huh. ???

How do I get the files to install on my iphone

How do I get the files to install on my iphone
Which one are you trying?
The Numbers app file you can download directly to the iPhone... it opens with the Numbers app.
The GoCalc file you have to download to a computer than install using the GoCalc app... details are in the app's instructions.
If you want a "stand alone" app (that doesn't rely on another app or program) you can run the Calcapp calculator (https://connect.calcapp.net/?app=qq0pg0#/)... it runs in a browser. It sets the USB height by measuring directly to the wheel.
If you want a "stand alone" app that sets the height by measuring to the machine, I suggest SchleifJunkies app (https://schleifjunkies.de/en/produkt-schlagwort/software-en/).
I don't get this form opened in goCalc
USB Angle Calc-Universal (Public0.6) .numbers it is available on the Iphone

It looks like you have the GoCalc app installed OK.
The other file that you posted above works in the Apple Numbers (https://www.apple.com/numbers/) app. It gives the same results, just a different option.
I added a link to freejack's calculator (https://forum.tormek.com/index.php?topic=4666.0) in the first post... it works on both iOS and Android, can be installed and run as an app, and gives answers for both measuring to the machine, and measuring directly to the wheel. (Should have done this sooner). :)

I've only just found this thread, and really like the Visual Angle Calculator. It's very easy to see where to input any changes. I compared it to the numbers spreadsheet that I put together (based on Dutchman's work) and it agrees well. Thank you cbwx.
