General Tormek Questions / Re: US-103 & US-105 difference...

Last post by tgbto - Today at 09:00:20 AM

The standard US-103 support can handle knives with blades up to 200mm (8 inches).

With very little wiggle room to choose where to clamp the knife, though.

Knife Sharpening / Simple Platform Jig

Last post by tgbto - Today at 08:55:42 AM

Hello,

Having no metal machining skills nor equipment and few parts to tinker with, I thought I'd give a try at a simple "Platform Jig" that I could 3D-print.

There is nothing fancy or innovative with a simple adjustable plate to rest a blade against, it just feels like it's missing from the Tormek jig lineup.

The objective is to be able to accomodate as wide a range of angles as possible, not limited to short blades but well suited to those as the SVM-00 is kinda fidgety.

I'll use PLA filament for the prototypes and ASA for the real thing, trying to avoid supports except snug ones for the two holes for ruthex inserts (thumbscrews) where geometry matters little.

A quick note on a design choise (which I am not sure is wise): the (grey) sliding platform is more or less self-locking inside the (blue) support. One has to flex it a bit by pressing down in the middle so it slides easily, then release it so it locks back in place, and the (red) back thumbscrew is just here to secure it in place and prevent bending. I might have to play with tolerances and/or add a bit of teflon or the like on the outer surfaces in contact with the support so it slides more smoothly but still locks without significant radial play..

[edit]And a second note : I might not be able to dispense with having to add a metal plate on top on the side of the slide that is close to the wheel, if I have to thin the tip and keep everything rigid.[/edit]

Please feel free to give any feedback that I could incorporate before the first actual prints.

Cheers,

Nick.

Knife Sharpening / Re: New angle jig KS-123

Rich Colvin has a jig he made for using with the SE-77 that you might find helpful...

I do have that but I tend to use the marker method for a one off. I have a set of chisels to do then I'll use the marker method for the first one, set the projection with a small double square then use that for the projection on the rest.

Fredrik,
If you are working in a limited space, the "maybe in the future" argument seems logical. The standard US-103 support can handle knives with blades up to 200mm
(8 inches).

Knife Sharpening / Re: New angle jig KS-123

My KS-123 arrived today. I first set up to sharpen a kitchen knife using the KJ-45 jig with the KS-123. After getting it all adjusted, I then measured the projection and entered the values into Calcapp which said the USB height should be 88.6mm. Measuring this after the angle setter was used yielded 88.7mm.  I'd say this is well within specs of my inexpensive digital caliper used to take the measurement.

Even the first setup was quick after having watched the Tormek video.

I then used the angle setter to set the honing angle to 1 degree greater. Simple, with great results.

Knife Sharpening / Re: SP-650 use on SJ-250

Last post by John Hancock Sr - Today at 12:58:59 AM

Comments under the video about how to use the SP-650 Stone Grader on Tormek's own website appear to disagree.

https://tormek.com/en/products/accessories/sp-650-stone-grader#h-Specsanddetails

"The fine side gives the surface of the stone up to about 1000 grit."

Your quote only relates to the SB and SG wheels.
When speaking in relation to the SJ wheel the description says
"You can also clean your SJ-250 Japanese Waterstone or SJ-200 Japanese Waterstone in the same way, but with the fine side of the SP-650 Stone Grader."
Which is exactly what has been said by me and others. Indeed the "stone grader" is really an old fashioned dressing stone that has the benefit of temporarily increasing the effective grit of a lower grit wheel.

As cbwx34 says, there are many paths leading to Rome and the grader is just one. Experiment with the various methods and settle on one which suites your purposes.

If you are going to get the KS-123 and use Tormeks adapter or a FVB having both the stock support and the extended one will save you some time. You rarely need the extra length but I have the longer bar set up on the grinding side and the stock wheel on the leather wheel side. This wat I don't have to move or adjust anything as I try and use the same projection distance when possible.

It may "rough it up" a little, but the SJ stone is so soft, the affect would be short lived.  I would also add that they don't consider the SJ stone as having "adjustable grit".

However, although the Tormek website says you can use the 1000 side to clean the SJ stone, Tormek in one of their online videos recommends not using it at all...

Instead, they suggest to use a scotchbrite pad, or as tgbto said, a rust eraser (which is what I use also.)

General Tormek Questions / Re: Product News - KS-123 Knif...

What I wrote in a previous message New angle jig KS-123
I had the pleasure of testing the new angle setter KS-123. It is based on ideas from Perra and meets all expectations.
Quote from my conclusion:
It's a wonderful tool, well designed and beautifully realized. I will definitely start using it. So no more 'Dutchman's tables', kenjigs, spreadsheets or apps on smart phones or tablets. End of an era that began on April 14, 2014 with my publication of "Simple adjustment of the grinding angle". It took 10 years, but now it can be even simpler and more accurate.

Attached is my test report in PDF file.

Dutchman, Thank you for a great review. I have one on order, should have it in a couple weeks.
