Knife Sharpening / Re: T-8 with DRO

Quote from: micha on April 11, 2023, 11:56:57 PMDear fellow Tormekers,

I just want to share my attempt of adding DROs to the machine. It's still kind of beta-testing - but so far I'm very happy with the results.



Hi micha

I like your solution- Maybe we can work together. Your solution together with my Angle setter. And an electric stepper motor that automatically sets the USB height according to the selected angle. Then we can make an app for the phone that controls everything.  ;D  ;D

Quote from: TireguyfromMA on April 26, 2023, 05:14:28 AMPerra, very impressive! You singlehandedly, and unknowingly, came up with the same tool that TORMEK was working on. One question about the function of this more precise angle setting tool. If I set it up to sharpen  at 12dps on a 250mm wheel, can I then use it on the 215mm leather or composite honing wheel to accurately hone the same knife by just changing the wheel diameter setting?

Hi
Thanks for kind words!
Yes you can do that. Put the tool on the honing wheel and it adjusts the scale according to the diameter of the wheel by itself, just release the locking screw on the back and press down a little gently, then of course you have to adjust your usb support up or down so you get the same angle or whatever angle you want to use . The purpose of the tool is to be able to easily set the usb height on different wheel diameters with as few other adjustments as possible. If you have set the jig-projection length correctly, one time, from the beginning, you only need to adjust the usb height to show the angle you want. You have to do that yourself, set the usb height, for now. Perhaps an improvement - self-adjusting usb height  ;D  ;D

Hi. No problems with engine power or noise. Its strong enough and quite silent.

Hi
I also have one of this fine old machines. But I have converted it into a honing station with a Tormek leather disc instead, Now I also have a usb support on it.

Hi Ken
Thanks for your comments.
I fully understand Tormek's actions. They must of course be careful about their patents and fine tools. Too bad they didn't check more often among all the posts we make, then maybe I would have received a signal earlier because I posted my prototypes gradually since a long time ago. But everything usually works out and we have been in contact and I am invited to Tormek for a visit.
I will give them a present. you probably know what... ;D
So if you also want a gift you must become my friend first.... ;)

Thank you Samuel
I really hope I didn't cause problems for Tormek! I really had no idea you were working on a similar project. If I had known, I probably wouldn't have published anything before your launch.
I do this on a hobby level. I have no intentions to produce or market and sell my product on the market. Just a couple of copies for my friends. So it's no problem for me.
You are of course welcome to take part and use everything I have shown if it is something that can improve your products. I would only be proud if I can be of use to Tormek.
It is exciting that we arrived at similar principles for our solutions. Congratulations to your development team and me.  :)
Regards. Per Perra

Thank you for all the nice reviews and kind words. I personally think it turned out really well and my tests so far have been positive in terms of angle accuracy. Especially when it adjusts to different wheel sizes.
And it works well with other knife jigs too, not just the Kj-45.
Now I'm looking for a new rabbit hole... ;D  ;D

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!

The best thing about Calcapp is that it works so well on the phone, it's always close at hand in your pocket. :)

Quote from: cbwx34 on March 27, 2023, 11:04:09 PMI have some indirect evidence as to why this occurred.  Until I get the needed evidence to prove or disprove it (you know who you are),  ;D  my current theory is that the horizontal measurement is based on the time zone it's set in.  Beginning in the Eastern Time Zone, subtract approx. 1.67 mm for every time zone as you travel west.

(Don't measure on the day the time changes either way.)

(If you're in Sweden just use the AngleMaster.)


:D  :D  :D

I'm happy to live in Sweden.... avoids all this calculation  ;)

I have never had to scrape mine, the waters seem to keep it clean. But technically, it should be possible to carefully scrape off the surface a little. But try some water or liquid first I would suggest.

Here is another method to get your measurements. In the text there is a "Download here" to download an excel file.

Can confirm that water works for me too. I use a simple spray bottle and shower a bit when it gets dry.
