Grindstone SG-250 possible defect

[kolekoll]

Hello. Does your SG-250 also has such small " nick" on top surface ? When I got it brand new, there was a light spot on grindstone, after first trueing I noticed a very small hole, I thought, that it will go away, but now my grinding stone has a diameter about 243 and the hole gets bigger. Is it normal or I have a faulty grindstone ?  I'll listen any suggestion   I'll include a link with pictures http://nagi.ee/photos/tartustuff/sets/404891/

It's definitely not normal to have a hole in the grindstone. Sounds like a defect to me.

That's not normal.  When I first got my machine areas of the wheel had abnormal pitting.  First just one spot then other larger areas developed.  Dressing the wheel did not remove them, it simply uncovered other areas.  It was nasty as these areas would grab a blade and pitch it back.  Tormek replaced the wheel and no more problems. 

My wheel was not exactly what you show.  This is what one of the smaller areas looked like:

Thank you Ken for advise. I was planning to do that, but thought, I'm asking before from this forum members.

Ken, everything is allright . I do appreciate all of your respond ! I already sent a question to Tormek support in Sweden. I'll see, what they answer .

[Ken S]

Let us know what you hear from Sweden.

Keep in mind that, unlike some of us insomniac forum fanatics, the support people have a family life on the weekends. I would consider a response by Monday excellent service.

Yeah, since I live in Estonia, I know, that in Friday evening usually people in Nordic countries trying to go to home as fast as possible and forget all work related duties

[Ken S]

Why should the Nordic people be any different than the rest of the world?

Ok, here is the suggestion from Sweden.
Hi,
Sorry for this, It should disappear after you true it sometimes but it's not supposed to be like this.
My suggestion is that you measure the stones diameter, and true it down until the hole is gone.
Measure it again and let me know how much you had to remove. I will compensate you in some way for this.

Best Regards,
Stig Reitan

Based on your pictures, that's a pretty ugly looking hole, and an obvious defect.  They should have a new wheel already in the mail to you, instead of asking you to true it out.  I see it as their problem, not yours.   It's a brand new stone.   But that's just me.  I sure hope they come through for you.    RR

REM ... That what actually I hoped too, but ok, I'll grind it down until  that hole disappears ( it is actually gets bigger, when using grinding wheel for sharpening and trueing, in near future I can't use this stone anymore, may be just for trueing only   ), but for some reason I think, the SG-250 will look after that like a donuts ring .. It shrinked already from 250  to about 243 .. with using some sharpening and then trueing and trueing and trueing

[Ken S]

Having had the chance to meet with Stig on several occasions, I trust him to do right by you.

A new replacement grinding wheel would seem the ideal solution to me. That said, it may not be the only desirable option for you. I would have faith. Grinding wheels, like brake shoes, areconsumables. They are very useful, but not precious.

Grind away the defect. Use the wheel; it should have plenty of life remaining. Compensation in some way may well be worth more than a few millimeters of grinding wheel.

Keep us posted.

If the stone is new I would definitely not accept to true it.

At first that is not a work a customer has to do and second who guarantees that the defect does not reach deeper down in the structure of the stone.

For me Tormeks answer is totally customer unfriendly and not legal in Germany. (The whole EU?)
