General Tormek Questions / The chip SG stone made
« on: November 19, 2019, 06:07:34 am »
I used SG-250. The dressing is done by diamond plate(#80 >>> #400). After that, I did honing on leather wheel.

But I could find chip on the edge. Could you tell me what's wrong?  ???

Knife Sharpening / Alternative FVB
« on: November 07, 2019, 12:27:48 pm »
I hope to introduce an alternative Frontal vertical base.

This solution was introduced at a small knife forum in Korea.

Surprisingly, this is the accessory of a JET wet sharpener.

General Tormek Questions / Re: Simple way to increase Tormek RPM by 40%
« on: October 17, 2019, 03:18:24 am »
Very clever!

In South Korea, Tormek T8 runs at 112 RPM.

So if I do it, T8 will run at 156 RPM.

Did you feel any wobble? My Rikon low speed buffer has it.

Knife Sharpening / Re: Best BESS score by edge angle
« on: September 17, 2019, 01:37:42 am »
Actual angle was 17.5 degrees.(Target angle was 16 dps.)

Sharpening & honing with Tormek(FVB & Software) and finishing with Jende kangaroo leather strop & Jende diamond emulsion 0.25micron.

Tester was PT50A.

Maybe it will be off topic, but which sharpening angle do you use? to have this kind of problem.

It depends on width. Generally over 20 degrees.

Sharpco, I am unclear about your last post. Would you please quantify "a high angle" in degrees. Also, would you please post a comparable photo of the smaller knob rubbing? I would like to understand.

Another option which I have used is a standard M6 thread hex bolt. I ground the hex head thinner with my Viel. (I did this as part of an unsuccessful attempt to make a Torlock platform into a small platform by reversing it. The thin bolt looks like it might work for other applications.)

It's hard to tell you exact angle. But when honing narrow blade e.g.paring knife at high angle, problem is occurred. I think grub screw is the best solution :)

I don't know exactly. But I know that many Koreans said "For kitchen knives except sushi knives, it is best to finish with 2K~5K." They use whetstones like Chosera, Shapton Pro etc.

Sharpco, I think Ken's suggestion of a smaller thumb screw provides a better solution as you don't need to fiddle around with a hex key. I have a selection of lower profile thumb screws I recently bought from China and I have checked and these work also.

I'm pleased to be able to hone using the USB in the horizontal position should the need arises again, so thank you for raising the question as it made me revisit the issue.

I think Ken's solution is not enough. When honing at high angle, it'll still cause problem.

Sharpco,
Another workable solution is the 7190 knob screw from the SE-77 jig. Here is a page showing it:

https://advanced-machinery.myshopify.com/pages/se-77-parts-diagram

I tried fitting it on my SVM-45. It fits well and does not extend beyond the jig.

Ken.
That's a good idea too.

Ok, I guess the best way to achieve this is to switch the SVM-45 knife jig thumb screw with a M6-sized grub screw which you can tighten up flush with an hex key. I took one from a 12mm collar I had lying around (see pic)


Edit: meant to point out that you can see that I tried to use my SVM-45 at a fairly acute angle :)

M6 grub screw! Good idea! Thanks :)

I faced this same issue when I first attempted to use the USB to hone a knife on the leather wheel, which I guess is why much of the literature I have read suggests that knife honing on the Tormek leather wheel is done freehand.

I stand to be corrected but the only way around this issue is to mount the USB in a Front Vertical Base so the SVM-45 knife jig will not snag on the support bar pillars.

I'm not skillful at freeehand honing. And I already have FVB but I'm looking for honing method not using FVB.

Support and knob are interfering. Is there any solution?
