Chord-Tangent Angle Compensation

[tgbto]

Thank you for the kind words. I modified it slightly to fix a few bugs and so it is easier to read/understand. I still have a 1.5 difference in H_USB with TormekCalc which I can't explain...

I have a request from a member to move this topic to knife sharpening. I have no problem with it in either group. I would like some feedback from the members before deciding.

Hi,

I made a calculating diagram simulate TTS-100's design.  It can help you make your version TTS-100 type jig.  Hope it help.

I didn't out of topic, I did the chord-tangent line compensation on it. Same as previous, you have to figure out Ton's real projection to apply it.

Regards,

Benjamin

I add it at first page also.

That would be me.

I figured that since it's related to Dutchman's work, it would be more appropriate there.

As a sidebar, in GeoGebra, you can "turn on" the geometry part used to solve the Knife Angle calculator.  I found the different approaches taken by benhung and tgbto interesting...

(Maybe I'm easily amused.)

No objection, Sir. At least for the part I designed, it works with the knife jigs only, due to the way their handle lies on the USB.

I will move the topic.

I made a diagram for SVM-45.

Ps.
Anyone who need a special version for your own(design) jig, give me a mail.  I can make one for you, just give me your jig's dimensions & photo.

One thing I found, is that the Sliders don't work well on a phone.  I managed to figure out how to convert them to Inputboxes...

...(that's a screenshot from my phone.) Between that and making the font larger (32pt in this example), it works a bit better.  With your knowledge/skill, you could probably come up with better ideas.

Hi, I am a complete Newby and read this thread carefully. There is one thing I still do not understand: the USB Base point (height). What is it needed and adjusted or measured? Maybe it is a dumb question, but I don't currently own a Tormek.
Thanks for understanding and support!
