If you want to work with an angle cube to set grinding angles, this little simple tool "zeroing plate" might be helpful.
No mathematical formulas or programs are needed, nor measurement of usb height.

I think this topic has been up in the forum before but I don't think I've seen this method.
As a result of working with the "Black edition" protractor, some ideas emerged that have resulted in, for example, this small tool.
It's almost the same principle as the Knife Angle Setter, three points on the wheel, but instead of a graduated scale I use a Digital Angle Cube.

It consists of four parts that are easy to 3-d print if you have access to a 3d printer, of course.
And one of them is of course my favorite The T-Cube.

The simple zeroing plate works well directly with the SE-77 and with the T-cube the knife jigs also work well, such as KJ-45 and KJ-140.
Of course, you have to do the procedure a few times as I described in the pdf file because the zero position moves when you adjust the usb support,
but it goes very quickly and is a very simple procedure. I feel that you quite quickly find a good way to work with setting the right angle.

I've included a description with images, text and links to parts in the attached PDF file for anyone who might want to try making one of their own.
It is free to download and 3d-print and use as you wish.

Right now this is my favorite method for setting angles quickly when sharpening knives. And I am completely satisfied with the accuracy and think it is good enough for my requirements.
Hope someone finds it interesting and wants to try it. You are welcome to return with comments if you 3d-print your own copy and test it. Or if you have other views or ideas on the topic.


Don't forget to give a "plåster" to your customers in case they need to feel how sharp the knife became after your work.

Hi Ken and all of you other out there
Now are the third generation of my angle setter tool complete and you asking for more information about it in the previous thread. So here it is.

I call it the Knife Angle Setter "Black Edition" (In honor of Tormeks 50th anniversary)

The tool allows you to work very easily and quickly with angle setting between e.g. grinding and honing where you want to use the jig to hold the knife, it helps to set the usb support at the right height. No measurements or calculators are needed to use it, nor any other measuring tools. It may look complicated but it is very fast and simple to work with and easy to learn to use and understand.

The most exciting thing about it is that it is based on a self-adjustment function for different grinding wheel sizes, 150-250mm that means it works for both T4 and T8. The principle could maybe also work for other tools as well.

Enclosing two documents with explanation and pictures where you can read more about it.

I hope there is someone who likes the idea and maybe gets inspired to make an own copies. It might be little difficult for those of you who don't have machines, tools and opportunities to produce all the parts needed, but the principle it is based on can perhaps be used as inspiration.

The project grew a bit from the first prototype as I received questions and suggestions from you members that pushed me to develop and improve the first variant. Thank you so much for your inspiration.
It has been an exciting rabbit hole anyway. 

Hope you like it!

I've been busy trying to see how accurately and repeatably you can grind with a Tormek. I know it's a little geeky and maybe not always necessary with exact angles to sharpen some knives for the wife!
There are several fine and precise calculation programs now that give us all the measurements we need, but I have had difficulty measuring these measurements with insufficiently high accuracy.  I think measurements within 0.1 mm are needed! Therefore I use calipers to measure with in my jigs.
Mainly talking about usb height and projection distance.  How to easily find the center line on different sizes of wheels and the height of the usb support? How easy and accurate to find projection distance on knives even if you angle them differently in the jig?
I have made two new measuring jigs for this purpose. They help me work faster and more precisely when I work with knife grinding. I can also rehearse my angles and measurements more accurately with these jigs.
Perhaps it may be of interest to some of you to take part of what I have worked with. Or maybe i can inspire someone. Or do you also have ideas on the same theme to share?
More pictures and information can be found in the excel file "Angle Calculator Lite V1.4" which is updated in this link. https://forum.tormek.com/index.php/topic,4885.msg37303.html#msg37303

Is there anyone more than me who had difficulty measuring the correct height of the grinding wheel to the Usb? I had difficulty measuring straight against the grinding wheel and wanted a 90 degree surface to measure against instead. I have searched for suggestions and tips but not found anything where you measure with calipers etc.
So it became a prototype like these. I've been thinking about 3D printing one or making in metal.
Any other suggestions or tips!

Hello sharpening friends!
I have read and studied several of your tips on how to solve different problems. Very interesting and fun to see how the rest of you found clever solutions. Thank you.
Now I thought I would contribute with a small tool that I printed with the help of a 3D printer and that I have greatly benefited from when setting up my Tormek T8
It can be used to measure the diameter of the grinding wheel, height of USB from both the machine and the grinding wheel. I also use it to measure or set the length of the grinding jig.
What I'm most fond of is setting the angle using it, the ruler is 1mm thick and the distance underneath is 6mm so it's consistent with the jig's center line broadly. It is much easier to set the right degrees because you don't use the jig with a knife on it.
I do not attach a drawing or any measure because the only measure that is important is 6mm according to figure1. And that surface A and B are parallel with each other.
I think the pictures describe enough if someone is thinking of developing their own. I hope it can be a joy for any of you!
Regards
