Hey!

curious to know if you (who sharpen many knives per day) do the above for each knife or do something like:

I thought in the same way like you.
I solved it by buying a diamond wheel 360 for the first grinding, so the standart stone is always prepared to 1000.

Hi folks!
That was new to me.
The SJ-250 has to be mounted only with writing upwards.
If you do not so the rotation of the dics is not correct.
That´s the info from Tormek Customer Service.

For me that´s trash. So my next wheel is a CBN with 6µ.

Hello!
A s I understand, Durofelt has a problem.
There is no problem with the 250 rockhard

I'm not particularly worried about any mold for the following reasons:

2) The area of contact between the 2x4's on my new storage rack is very small.  It is maybe one cm² of contact area where the water could theoretically "wick" from the stone to the wood. Counteracting that moisture transfer is the large surrounding surface area of the wood, which is constantly drying out, trying to reach equilibrium with the (low) room humidity.

In my opinion that will bring the problem that the SJ get 2 gutters from contact.
Take a file or a micutter to put a slant in the contact area. With water the JS is so heavy and so limp.

Good luck

Thanks for your answeres.
But it hit not my problem.
I knew the video7.
I am only using the truing tool with the left hand so the weight of my arm is on the T-8 and not on the toolbar.
I only turn the threaded nut 1/20 of a round, count to 15 and turn then the next 11/20.
I only work with the truing tool from the outer to the inner side.
For the depth I only turn the toolbarthreaded nut 174 of the differenz between two numbers on it.
After truing I check the disc with a straightedge (lineal). Right and left side of the disc girth is down and the middle is up.

So I started truing again and tested out the startingpoint in the middle at the highest point of the girth.
But the result is the same.

for the moment I use the SE-77 and a diamantplate for truing.

I checked the SG-250 and it is correct flat.

Hello!
I use a Waterstone 250. I tried to truing the stone. It doesn´t work corretly.
I drive very slow from the outer side to the inner side. to check the line, I use a straightedge.
It´s aweful. It is a curve from innerside to the auter side. But it has to be flat.
How can I get a flat stone?

Hello Nico!
I marked on my WM-200 the 215mm for the letherwheel.

When you unpacked the T8, there was a dummy on the shaft. This you can use, when the grinding wheel is disturbing you.
On the other hand think about buying a frontbase and the greater toolbar. It is higher and longer.
With this parts you win a lot of space to handle the knives.

Another way is to buy a 250mm feltwheel. It is to use instead of the grinding wheel, but can use the configuration of jig and toolbar.
But not really. With a felt you cannot work against the blade.
A lot of videos say that the grinding angle is NOT alike the honing angle.

Hello!
Both of you have the right intension to my question. I was wrong using "microfase". Microbevel seems to be correct.

But how can I put a microfase on the edge?
I´m often reading about 18° GrindingAngel and than adding a microfase with 14° on it.
When parameters like thickness of the blade or distance between jig and edge are absolut items, I can only imagine that an indrustrial plane grinding machine and a sinus machine vise.
Is there an alternate method?

Thanks both of you for the explanaition.

Hello jvh!
The Excel sheet is superb to me.
What are the SWIFT banking data to send money to you?

Pietje

Working with the T8, I usually get an edge of 3-4mm. Now I like to get an edge with less 1mm wide. What technic do I have to use to get this result?

Thanks for info.

Hello forum!
Tormek gives the advice to use the DBS-22 with the SB-250, the black disk.
Why is no one using a diamond disc DC-250 for the DBS-22 to grind HSS-drills?
Pietje

I think 20 dps is quite an obtuse angle for a kitchen knife used for vegetables, which would explain the different results with onions vs. chives. I'd try someting between 13 and 15 dps instead and repeat the onion experiment.

The edge retention study that Nick mentioned was also very interesting - you may find the provisional results here: http://knifegrinders.com.au/CATRA-report.htm. Quite a surprise regarding the Sabatier!
Mike

Thanks for your hint. I have changed to 14 dps and used a HardRock for deburring. Now it works well with an onion. I check out, how long the sharpness is standing.
The report is awesome. The knife was expensive.
